Fabspeed Competition Conversion Kit - For Fabspeed Valved Exhaust. 

The Fabspeed Porsche 981 Cayman GT4 / Boxster Spyder Competition Conversion Kit is a lightweight performance exhaust upgrade designed to transform an existing Fabspeed Motorsport Valvetronic Exhaust System into a louder, lighter and more aggressive competition-style exhaust configuration.

Fits:

• Porsche Boxster 981 Spyder 3.8L 2016
• Porsche Cayman GT4 3.8L 2015-16  

Developed specifically for the Porsche 981 Cayman GT4 and Boxster Spyder models manufactured between 2015 and 2016, this conversion kit eliminates the valved exhaust section of the compatible Fabspeed system and replaces it with direct-flow stainless steel muffler bypass pipes.

The result is an uncompromising exhaust configuration that emphasises the distinctive sound of Porsche's naturally aspirated 3.8-litre flat-six engine.

The original Fabspeed Valvetronic Exhaust System provides adjustable exhaust sound through its electronically controlled, vacuum-actuated valve arrangement. This allows the driver to switch between quieter and more aggressive exhaust characteristics.

However, for Porsche enthusiasts who prefer maximum exhaust volume and a more focused motorsport experience, the additional valve hardware and associated sound-control features may no longer be required.

Fabspeed developed the Competition Conversion Kit to provide a straightforward alternative.

By replacing the valved section with fixed, free-flowing bypass pipes, the kit removes the need for exhaust valve operation in that section and delivers a consistently aggressive exhaust note.

Manufactured in-house by Fabspeed Motorsport from high-quality T304L stainless steel, the conversion pipes use a 2.5-inch (63.5 mm) diameter design to maintain an unrestricted exhaust path.

The kit also reduces exhaust system weight by approximately 11 lbs (5 kg) compared with the corresponding valved portion of the Fabspeed Motorsport exhaust.

This weight saving contributes to a lighter exhaust configuration, particularly desirable for track-focused vehicles where reducing unnecessary mass is an important consideration.

Installation is designed to be straightforward. The competition pipes bolt directly into the existing Fabspeed exhaust arrangement using the current Fabspeed AccuSeal clamps.

No cutting or welding is required, and the modification is reversible, allowing the original Fabspeed valved section to be reinstalled if a quieter exhaust configuration is required.

The Competition Conversion Kit is particularly suitable for dedicated track cars, motorsport-inspired builds and Porsche owners seeking the most aggressive sound available from their compatible Fabspeed exhaust system.

Important: This kit is only suitable for Porsche 981 Cayman GT4 and Boxster Spyder vehicles already equipped with the corresponding Fabspeed Motorsport Valvetronic Exhaust System. It is not compatible with the standard Porsche factory exhaust.

What This Product Does:
The Fabspeed Competition Conversion Kit replaces the valved section of the existing Fabspeed Motorsport Valvetronic Exhaust System with straight-through muffler bypass pipes.

Its primary functions include:

• Converts the Valved Exhaust into a Competition Configuration: Replaces the relevant valved section with fixed, direct-flow exhaust pipes.
• Eliminates Exhaust Valve Operation: Removes the adjustable sound-control function from the converted section.
• Creates a Louder Exhaust Note: Produces a consistently aggressive exhaust sound without the quieter valve setting.
• Enhances Flat-Six Engine Sound: Makes the distinctive 3.8-litre naturally aspirated Porsche engine more prominent.
• Reduces Exhaust Weight: Saves approximately 11 lbs compared with the original Fabspeed Valvetronic section.
• Provides Direct Exhaust Gas Flow: Uses straight-through pipework instead of the valved muffler arrangement.
• Supports Motorsport Applications: Provides a lightweight, high-volume exhaust configuration for appropriate track-focused use.
• Maintains Stainless Steel Durability: T304L stainless steel construction offers resistance to corrosion and high exhaust temperatures.
• Preserves Compatible Fabspeed Connections: Uses the existing exhaust mounting arrangement and AccuSeal clamps.
• Allows Reversible Conversion: The original Fabspeed valved section can be reinstalled without permanent exhaust modification.
• Simplifies the Converted Exhaust Section: Eliminates the valves and their moving mechanisms from the replaced portion of the system.
• Maintains the Existing Catalytic Converters: As a cat-back conversion, it does not require removing the vehicle's catalytic converters.

Symptoms Of Wear Or Failure:
The Fabspeed Competition Conversion Kit is primarily an exhaust performance upgrade, not a routine maintenance component.

However, it may also be considered when an existing compatible Valvetronic exhaust section has become damaged or when an owner wishes to eliminate the associated valve mechanism.

Common problems affecting the existing exhaust system include:

• Exhaust sound does not change when the valves are operated.
• A valve becomes stuck open or closed.
• Inconsistent response from the valve system.
• Metallic rattling around the valve assembly.
• Irregular or incomplete valve movement.
• Ticking, hissing or blowing sounds.
• Unexpected exhaust noise.
• Soot marks around pipe connections.
• Exhaust fumes near the vehicle.
• Increased noise under acceleration.
• Heavy rust or corrosion.
• Weakened welds.
• Cracked mounting points.
• Perforated pipe sections.
• Loose or damaged hardware.

Why Replacement / Upgrading Matters:
Installing the Fabspeed Competition Conversion Kit changes the character and weight of an existing Valvetronic exhaust system.

The main advantages are reduced weight, simplified exhaust construction and a more aggressive, consistently loud exhaust note.

• Maximum Exhaust Sound: Removes the quieter valved operating mode and delivers a consistently aggressive exhaust character.
• Motorsport-Inspired Driving Experience: Emphasises the sound of the Porsche 981 GT4 and Spyder's naturally aspirated flat-six engine.
• Approximately 11 lb Weight Reduction: Eliminates weight associated with the replaced Valvetronic section.
• Simplified Exhaust Arrangement: Removes moving exhaust valve mechanisms from the converted section.
• Direct Exhaust Flow: Uses 2.5-inch stainless steel bypass pipes.
• Durable Stainless Steel Construction: Manufactured from corrosion-resistant T304L stainless steel.
• Compatible with Existing Fabspeed Systems: Designed specifically for the corresponding Fabspeed Valvetronic Exhaust.
• Reversible Modification: Allows the original valved components to be reinstalled.
• No Cutting or Welding: Uses the existing exhaust connections for bolt-on installation.
• Ideal for Track-Focused Builds: Provides a lighter, louder exhaust configuration.
• Reduced Dependence on Valve Components: Eliminates valve-related mechanical operation from the replaced section.
• Fabspeed Motorsport Engineering: Manufactured by a specialist performance exhaust producer.

Porsche 981 Boxster / 981C Cayman SOUL Performance Exhaust System

High quality mufflers offer a refined, sporty tone with minimal drone. Gain the enhanced response, character, and sound that your Porsche deserves.

•   Fits all Porsche 981 Boxster / Cayman models (2013–2016)
•   Direct bolt-on installation with included instructions
•   Choice of multiple exhaust tip styles and finishes—or customize your own

•   Covered by SOUL’s Lifetime Warranty for street and track use

DEWELOPMENT:
Following the success of our Valved Exhaust and its ability to fight drone, we wanted to offer a lighter, valveless version that offers an invigorating exhaust note (just like valves open mode on our Valved Exhaust) at all times with the least amount of undesirable elements like droning and rasp. This system is perfect for those who crave an aggressive sound to pair with aftermarket headers and not have it be overbearingly loud. The volume level is delightfully greater than that of PSE (Porsche Sport Exhaust) with valves open while retaining a refined exhaust note. This system is also beneficial for track cars looking for maximum flow in an exhaust but must mind decibel readings. The mufflers are incredibly effective at minimizing drone and encourage a fuller, more robust tone befitting of a Porsche.

CONSTRUCTION:
Each system is constructed from mandrel-bent T304L stainless steel tubing, including robust 2.5″ over-axle pipes, and paired with mufflers reinforced for maximum durability. SOUL mufflers are packed with premium sound-absorbing material engineered to withstand long-term use without breaking down or blowing out.
For a personalized look, select from a wide range of 321 stainless steel exhaust tips in various styles and finishes—or work with us to create a fully custom set. For those seeking performance advantages, titanium single-wall tips are also available, offering the same striking appearance while saving nearly a pound of weight compared to stainless steel.

BOLT ON AND GO:
Each exhaust is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure it arrives in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.

LIFETIME WARRANTY:
Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any questions or issues that you may have.

SOUL Performance Exhaust System.

The SOUL Performance Exhaust System is a high-quality aftermarket sports exhaust upgrade designed specifically for the Porsche 981 Cayman GT4, Boxster Spyder and GT4 Clubsport models manufactured between 2015 and 2016.

Fits:

• Porsche Boxster 981 Spyder 3.8L 2016
• Porsche Cayman GT4 3.8L 2015-16  

Developed for the naturally aspirated 3.8-litre flat-six engine, this performance exhaust system replaces the original rear exhaust assembly with a lightweight, non-valved stainless steel design incorporating performance silencers and a choice of premium exhaust tips.

The Porsche 981 GT4 and Boxster Spyder are renowned for their responsive engines, distinctive high-revving exhaust character and engaging driving experience.

SOUL Performance has engineered this exhaust system to enhance those characteristics by providing a more direct exhaust flow arrangement and a stronger, more pronounced engine sound.

Unlike a conventional valved sports exhaust, the SOUL Performance Exhaust System does not incorporate electronically operated exhaust valves.

Instead, it provides a consistent sporting exhaust note whenever the engine is running.

SOUL describes the system's sound as similar in character to its Valved Exhaust System with the valves open, but with carefully developed mufflers to minimise undesirable drone and rasp.

The exhaust is designed to produce a deeper and fuller tone than the factory Porsche Sport Exhaust (PSE), with the manufacturer describing its volume as greater than PSE in the open-valve setting.

However, the system is not intended to produce an unnecessarily harsh or excessively resonant sound during normal driving.

Its performance silencers contain high-quality sound-absorbing material designed to withstand repeated heating and cooling cycles without prematurely deteriorating.

The reinforced muffler casings are engineered for durability under demanding operating conditions.

Manufactured from mandrel-bent T304L stainless steel, the system incorporates 2.5-inch outside-diameter over-axle pipes to provide a smooth exhaust gas path.

Mandrel bending helps maintain a consistent internal pipe profile through bends, reducing unnecessary restrictions compared with poorly formed exhaust tubing.

The system is also designed to be lighter than the equivalent SOUL valved exhaust arrangement by eliminating the exhaust valve mechanisms.

A range of exhaust tip styles and finishes allows owners to personalise the rear appearance of their Porsche.

Available options include single-wall and double-wall stainless steel tips, alongside lightweight titanium single-wall exhaust tips.

SOUL states that its titanium single-wall tips can save nearly one pound compared with the corresponding stainless steel tips.

Each exhaust assembly is quality-checked and tested in a dedicated fitting fixture before dispatch.

The system is designed for direct bolt-on installation on compatible vehicles, with manufacturer-supplied fitting instructions.

Backed by SOUL Performance's lifetime warranty, subject to the published conditions, this performance exhaust is suitable for owners seeking a more distinctive flat-six soundtrack, durable stainless steel construction and a simpler non-valved rear exhaust arrangement.

It is particularly attractive for Porsche enthusiasts who prefer a consistently sporting exhaust tone without relying on selectable valve operation.

What This Product Does:
The SOUL Performance Exhaust System carries exhaust gases from the engine's upstream exhaust components through the rear exhaust assembly and releases them through the exhaust outlets.

During engine operation, combustion gases leave the cylinder heads and travel through the exhaust manifolds and catalytic converter assemblies.

These gases then enter the rear exhaust system.

The SOUL exhaust uses mandrel-bent stainless steel tubing and specially developed silencers to direct the exhaust gases towards the rear outlets while controlling the resulting sound.

Its main functions include:

• Directing exhaust gases: Carries spent combustion gases through the rear exhaust and safely towards the outlets.
• Supporting efficient exhaust flow: Uses 2.5-inch over-axle tubing with smooth mandrel-formed bends.
• Enhancing exhaust sound: Produces a fuller, deeper and more aggressive naturally aspirated flat-six soundtrack.
• Reducing unwanted drone: Incorporates performance silencers designed to minimise low-frequency cabin resonance.
• Controlling exhaust rasp: Uses sound-absorbing mufflers to help maintain a refined exhaust character.
• Providing consistent sound: Delivers its sporting exhaust note without selectable exhaust valves.
• Supporting responsive engine behaviour: Provides a performance-oriented rear exhaust arrangement intended to complement the 3.8L engine.
• Maintaining upstream components: Retains compatible existing exhaust manifolds and catalytic converters.
• Improving rear appearance: Offers different exhaust tip designs and finishes.
• Providing durability: Uses corrosion-resistant stainless steel tubing and reinforced muffler casings.
• Reducing mechanical complexity: Eliminates the valve mechanisms found in a valved rear exhaust.
• Supporting performance modifications: Can complement compatible aftermarket exhaust headers and other appropriate upgrades.

Exhaust Sound Characteristics:

The SOUL Performance Exhaust System is designed to provide a stronger exhaust sound while retaining a level of refinement suitable for enthusiast use.

The manufacturer describes the system as producing a sound similar to the open-valve setting of its Valved Exhaust System.

The sound is intended to be greater in volume than the factory Porsche Sport Exhaust with its valves open.

Depending on the complete exhaust configuration, drivers may notice:

• A deeper exhaust tone at idle.
• A fuller and more robust flat-six soundtrack.
• A more pronounced exhaust note during acceleration.
• Greater sound intensity at higher engine speeds.
• Enhanced exhaust character during downshifts.
• A distinctive sporting tone during normal driving.
• Reduced unwanted drone compared with a completely unrestricted rear exhaust.
• A more refined character than a dedicated straight-through race exhaust.

Why Upgrading Matters:
The SOUL Performance Exhaust System is designed for Porsche owners who want a more pronounced engine sound and a simpler, performance-focused rear exhaust configuration.

1. Enhanced Flat-Six Exhaust Sound

The naturally aspirated 3.8L engine fitted to the Porsche 981 GT4 and Boxster Spyder produces a distinctive high-revving soundtrack.

SOUL's performance exhaust is designed to emphasise this character, creating a deeper and more aggressive exhaust tone.

2. Consistent Sporting Sound

Unlike a valved exhaust, this system does not switch between quiet and loud modes.

It provides a consistent performance exhaust character during everyday driving and more enthusiastic use.

This appeals to drivers who prefer a fixed exhaust sound.

3. Reduced Mechanical Complexity

The non-valved design eliminates moving exhaust valves and their associated mechanisms from the replacement rear exhaust.

This can simplify the exhaust arrangement compared with a system that requires valve actuation.

However, vehicle-side valve-control components may remain and should be managed according to the manufacturer's installation guidance.

4. Improved Exhaust Flow Potential

The system uses mandrel-bent 2.5-inch over-axle piping.

This design is intended to support efficient exhaust gas movement through the rear exhaust.

Specific horsepower or torque gains for this exhaust alone have not been independently confirmed.

5. Reduced Unwanted Drone

The SOUL mufflers use durable sound-absorbing materials to help control low-frequency resonance.

This makes the system an alternative to completely unrestricted rear exhaust designs.

6. Durable Stainless Steel Construction

T304L stainless steel provides corrosion resistance and suitability for repeated exposure to exhaust heat and vibration.

The reinforced muffler casings are designed for long-term durability.

7. Lighter Non-Valved Design

SOUL developed this exhaust as a lighter alternative to its valved system.

Eliminating exhaust valve hardware reduces the number of components within the rear assembly.

The exact complete-system weight saving should be verified before quoting a numerical figure.

8. Premium Exhaust Tip Options

Owners can choose from a range of single-wall and double-wall exhaust tips.

Lightweight titanium tips are available as an alternative to stainless steel.

This allows the rear appearance of the vehicle to be personalised.

9. Direct Bolt-On Installation

The exhaust is designed for direct installation on compatible vehicles.

SOUL Performance checks each system in an installation fixture and supplies fitting instructions.

10. Compatibility with Performance Headers

The manufacturer developed this exhaust to provide a sporting sound when combined with appropriate aftermarket exhaust headers.

Its mufflers help control unwanted resonance that may otherwise become more pronounced with freer-flowing upstream exhaust components.

11. Suitable for Enthusiast and Track Applications

The system provides an aggressive soundtrack while incorporating effective sound attenuation.

This may appeal to track users who require improved exhaust flow but also need to consider circuit noise limits.

Actual decibel readings must be measured for the complete vehicle configuration.

12. Manufacturer Lifetime Warranty

SOUL Performance backs its exhaust components with a lifetime warranty for street and track use, subject to the published terms and conditions.

Designed for Porsche's naturally aspirated flat-six engines, this system replaces the original rear exhaust assembly with a lighter, freer-flowing configuration that provides a more pronounced exhaust note without sacrificing everyday driving refinement.

The original Porsche 987.1 exhaust incorporates secondary catalytic converters, restrictive pipework and relatively heavy silencers. Although these components help control emissions and noise, they also influence exhaust flow, sound characteristics and overall vehicle weight.

SOUL Performance developed its exhaust system to enhance the driving experience by allowing more of the flat-six engine's distinctive sound to be heard during acceleration while maintaining a controlled exhaust tone during normal driving.

The system incorporates free-flowing, mandrel-bent T304L stainless steel tubing and specially designed performance silencers with reinforced outer casings.

These silencers are engineered to produce a deeper and more engaging exhaust sound under throttle while greatly reducing unwanted low-frequency cabin resonance.

Unlike a conventional straight-through race exhaust, the SOUL Performance Exhaust System is designed to remain refined during cruising.

The manufacturer specifically states that its silencer arrangement minimises drone, including when paired with compatible aftermarket exhaust headers.

This is a non-valved exhaust system, meaning that it does not require vacuum-operated exhaust valves, electronic controllers or additional valve-control equipment.

Instead, the sound characteristics change naturally according to engine speed and load.

During gentle driving, the exhaust produces a restrained sporting tone. Under harder acceleration, the engine delivers a stronger and more aggressive flat-six soundtrack.

SOUL Performance manufactures the system using corrosion-resistant T304L stainless steel tubing and reinforced performance silencers.

The mounting brackets are strengthened to help prevent fatigue cracking and other damage caused by vibration and repeated thermal cycling.

According to SOUL Performance, the replacement exhaust weighs approximately 21.7 lb (9.8 kg) compared with approximately 36.6 lb (16.6 kg) for the factory components.

This represents a manufacturer-reported saving of approximately 15 lb (6.8 kg).

Each exhaust system is quality-checked and tested in a fitting fixture to verify installation accuracy.

The kit is designed for direct bolt-on installation and includes new high-grade hardware for the header-to-exhaust flange connections, along with installation instructions.

Backed by SOUL Performance's lifetime warranty, subject to the manufacturer's terms, this exhaust is an attractive upgrade for Porsche owners seeking enhanced engine sound, improved exhaust flow potential, reduced weight and durable stainless steel construction.

What This Product Does:
The SOUL Performance Exhaust System directs combustion gases from the engine's upstream exhaust components through the rear exhaust assembly and out of the vehicle.

During engine operation, exhaust gases leave the cylinder heads and pass through the exhaust manifolds and primary catalytic converters, where fitted.

The gases then enter the rear exhaust system.

The SOUL Performance Exhaust replaces the factory rear arrangement with mandrel-bent stainless steel tubing and performance silencers.

Its primary functions include:

• Directing exhaust gases: Carries combustion gases safely towards the rear exhaust outlets.
• Supporting efficient exhaust flow: Uses smooth-radius, mandrel-bent stainless steel pipework.
• Reducing exhaust restriction: Replaces the factory rear assembly, including its secondary catalytic converters.
• Enhancing engine sound: Produces a fuller and more aggressive flat-six exhaust note during acceleration.

• Porsche Cayman 2.9L 987C MKII 2009-12
• Porsche Cayman S / R 3.4L 987C MKII 2009-12  

Developed for Porsche's naturally aspirated flat-six engines, this system replaces the original rear exhaust assembly with a high-quality stainless steel exhaust featuring free-flowing pipework, performance silencers and a choice of premium exhaust tips.

The factory Porsche Boxster and Cayman exhaust is designed to balance engine performance, exhaust emissions, noise restrictions and everyday comfort. However, its relatively small pipework and substantial silencer assembly can limit the volume and character of the engine's natural exhaust note.

SOUL Performance developed this system to deliver a fuller, deeper and more engaging flat-six soundtrack without the excessive cabin resonance often associated with less refined aftermarket exhausts.

The system uses mandrel-bent T304L stainless steel tubing, designed to maintain a smooth exhaust gas path through bends and reduce unnecessary flow restriction.

Its specially developed silencers incorporate sound-absorbing materials intended to minimise undesirable drone and rasp, particularly during steady-speed cruising.

Unlike the manufacturer's separate Valved Exhaust System, this version does not incorporate electronically controlled exhaust valves.

Instead, it delivers a consistently sporty exhaust tone, similar in character to the open-valve mode of SOUL's valved system.

SOUL states that the exhaust produces a greater volume than the original Porsche Sport Exhaust (PSE) with its valves open, while retaining a refined exhaust character.

The construction incorporates reinforced silencer casings and strengthened exhaust mounting brackets, designed to provide durability during repeated heating and cooling cycles, everyday driving and demanding track use.

A choice of premium exhaust tips allows owners to personalise the rear appearance of their Porsche.

Available options include different styles and finishes of 321 stainless steel exhaust tips, alongside lightweight single-wall titanium tips.

The titanium tip option offers a weight saving of nearly one pound compared with the equivalent stainless steel tips, according to SOUL Performance.

Each exhaust assembly is quality-checked and tested in a dedicated fitting fixture before dispatch to ensure consistent installation fitment.

The system is designed for direct bolt-on installation and includes new high-grade hardware for the exhaust header flange connections, together with comprehensive installation instructions.

Backed by SOUL Performance's lifetime warranty, subject to the manufacturer's published terms, this exhaust is ideal for Porsche owners seeking a more distinctive flat-six sound, durable stainless steel construction and a simple, non-valved performance exhaust arrangement.

What This Product Does:
The SOUL Performance Exhaust System carries exhaust gases from the engine's upstream exhaust components through the rear exhaust assembly and directs them towards the exhaust outlets.

During engine operation, combustion gases leave the cylinder heads and pass through the exhaust manifolds and catalytic converters.

The gases then enter the rear exhaust, where the tubing and silencers influence exhaust flow and sound.

The SOUL system uses free-flowing stainless steel pipework and specially developed mufflers to balance strong exhaust sound with controlled resonance.

Its main functions include:

• Directing exhaust gases: Carries spent combustion gases towards the rear outlets.
• Supporting exhaust flow: Uses mandrel-bent tubing to provide a smooth gas path through the rear exhaust.
• Enhancing engine sound: Produces a deeper, fuller and more sporting flat-six exhaust note.
• Reducing unwanted drone: Incorporates silencers designed to minimise low-frequency cabin resonance.
• Controlling exhaust rasp: Helps reduce harsh or undesirable high-frequency exhaust sounds.
• Providing consistent exhaust character: Delivers a fixed sporting tone without selectable exhaust valves.

• Complementing performance upgrades: Designed to work with compatible aftermarket exhaust headers.
• Retaining compatible upstream components: Allows the original exhaust manifolds and catalytic converters to remain fitted.

Exhaust Sound Characteristics:

SOUL Performance developed this system to provide a more aggressive exhaust note without the harshness or constant resonance of a completely unrestricted rear exhaust.

The manufacturer describes the sound as similar to its Valved Exhaust System with the valves open.

Owners may notice:

• A deeper exhaust tone at idle.
• A fuller flat-six soundtrack during acceleration.
• Increased sound intensity at higher engine speeds.
• More pronounced engine character during downshifts.
• A stronger exhaust note under heavy throttle.
• A more sporting sound than the standard Porsche rear exhaust.
• Reduced unwanted drone compared with less effectively silenced performance exhausts.
• A more refined tone than an unsilenced race exhaust.

Why Upgrading Matters:
1. Enhanced Flat-Six Engine Sound

The naturally aspirated engines fitted to Porsche 987.2 Boxster and Cayman models produce a distinctive flat-six soundtrack.

The SOUL exhaust is designed to emphasise this character, delivering a deeper and more engaging note during acceleration and high-RPM driving.

2. Consistently Sporting Exhaust Tone

Unlike a valved system, this exhaust does not require the driver to select a louder sound mode.

It provides its performance exhaust character whenever the engine is running.

3. Reduced Unwanted Drone and Rasp

SOUL's specially developed silencers aim to minimise unwanted resonance and harsh exhaust tones.

This provides a more refined alternative to unsilenced or poorly matched aftermarket systems.

4. Improved Exhaust Flow Potential

The system uses mandrel-bent stainless steel pipework designed to reduce unnecessary restrictions.

This may complement other appropriate performance modifications.

However, specific horsepower and torque gains have not been verified for this exhaust alone.

5. Durable Stainless Steel Construction

T304L stainless steel offers corrosion resistance and durability under repeated exhaust heating and cooling cycles.
