SOUL Performance Exhaust System. 

The SOUL Performance Exhaust System is a premium aftermarket sports exhaust upgrade designed specifically for the Porsche 987.2 Boxster and Cayman models manufactured between 2009 and 2012.

Fits:

• Porsche Boxster 987 MKII 2.9L 2009-12
• Porsche Boxster S 987 MKII 3.4L 2009-12
• 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.
• Maintaining durable exhaust construction: Uses corrosion-resistant stainless steel and reinforced silencer housings.
• Supporting secure installation: Incorporates strengthened brackets designed for extended road and track use.
• Enhancing rear-end styling: Offers a selection of exhaust tip designs and finishes.
• 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.

The reinforced silencer casings are designed for long-term use.

6. Strengthened Exhaust Mounting Brackets

Exhaust mounts experience vibration, thermal expansion and mechanical stress during driving.

SOUL incorporates reinforced brackets intended to reduce the risk of cracking or failure during road and track use.

7. Simpler Non-Valved Design

The absence of exhaust valves reduces the number of moving components within the replacement rear exhaust.

This can appeal to owners who prefer a simpler performance exhaust configuration.

8. Premium Exhaust Tip Options

The system is available with a choice of stainless steel and titanium exhaust tips.

Different styles and finishes allow the owner to personalise the vehicle's rear appearance.

9. Direct Bolt-On Installation

The exhaust is designed for installation using the original compatible vehicle mounting arrangement.

SOUL quality-checks and fixture-tests the assembly before dispatch.

10. Compatibility with Performance Headers

The system is designed to work with suitable factory and aftermarket header arrangements.

Its silencers aim to control unwanted resonance, even when a freer-flowing upstream exhaust system is fitted.

11. Manufacturer Lifetime Warranty

SOUL Performance provides a lifetime warranty for its exhaust components, subject to the applicable warranty conditions.

SOUL Race Exhaust System, Manual Transmission.

The SOUL Performance Race Exhaust System is a high-performance aftermarket rear exhaust developed specifically for Porsche 987.2 Boxster and Cayman models manufactured between 2009 and 2012.

Fits:

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

Designed for naturally aspirated 2.9-litre and 3.4-litre flat-six engines, this motorsport-focused system replaces the original rear exhaust with a lightweight, freer-flowing stainless steel arrangement.

Unlike conventional sports exhaust systems that balance sound, comfort and performance, the SOUL Race Exhaust has been developed primarily for track use, durability, weight reduction and efficient exhaust gas flow.

The system features mandrel-bent T304L stainless steel tubing with a 0.065-inch wall thickness, providing a combination of strength, corrosion resistance and reduced weight.

SOUL specifies 2.5-inch tubing for the main exhaust construction and describes the over-axle pipe profiles as 2.25 inches in diameter.

The over-axle sections are shaped to provide clearance around the rear axles and anti-roll bar drop links, including on vehicles fitted with lowered or modified suspension.

A key feature is the exhaust's bespoke mounting arrangement.

SOUL developed a transmission mounting brace and heavy-duty Mikalor band clamp system to reduce the stress associated with conventional exhaust hangers welded directly to the pipework.

Additional rubber vibration dampeners provide support to the over-axle pipes, helping manage movement and vibration during demanding driving conditions.

The mounting arrangement is also designed to be easier to repair or replace following an incident during motorsport use.

The system is manufactured in-house at SOUL Performance's Willow Grove, Pennsylvania facility.

Its stainless steel brackets are laser-cut, press-brake formed and TIG-welded, while the exhaust welds are back-purged to support durability.

SOUL Performance reports that its Race Exhaust weighs approximately 27 lb (12.2 kg), compared with approximately 46 lb (20.9 kg) for the original exhaust components.

These figures include the mounting brackets.

The resulting reduction is approximately 19 lb (8.6 kg).

The manufacturer also states that its bespoke mounting solution alone saves more than 5 lb compared with the original factory mounting arrangement.

The Race Exhaust is designed to produce an exceptionally loud and aggressive flat-six soundtrack.

Its reduced sound attenuation allows more of the engine's natural exhaust character to be heard, especially during hard acceleration and high-RPM operation.

However, this comes with a significant reduction in everyday driving refinement.

SOUL explicitly warns that exhaust drone will be present, even when resonators are fitted.

The manufacturer also advises against combining this exhaust with aftermarket headers for normal street driving because of the resulting sound characteristics.

Owners seeking a quieter or more refined exhaust should consider SOUL's separate Valved Exhaust System.

The Race Exhaust is designed for direct bolt-on installation on compatible vehicles and includes high-grade header-to-exhaust flange hardware and installation instructions.

Backed by SOUL Performance's lifetime warranty, subject to the manufacturer's conditions, this system is an upgrade for Porsche owners seeking a lighter, more durable and more aggressive exhaust arrangement for track-focused applications.

What This Product Does:
The SOUL Race Exhaust System carries spent combustion gases from the upstream exhaust components through the rear exhaust arrangement and directs them towards the exhaust outlets.

When the engine operates, exhaust gases leave the cylinder heads and travel through the exhaust manifolds and catalytic converters, where fitted.

The gases then pass into the rear exhaust system.

The SOUL Race Exhaust uses a freer-flowing pipe arrangement with substantially less emphasis on sound attenuation than the original Porsche exhaust.

Its primary functions include:

• Directing exhaust gases: Carries combustion gases towards the rear outlets.
• Supporting efficient exhaust flow: Uses mandrel-bent stainless steel pipework.
• Reducing rear exhaust restriction: Provides a more direct exhaust route than the heavily silenced original rear assembly.
• Enhancing engine sound: Produces an aggressive motorsport-style flat-six soundtrack.

It creates an extremely aggressive exhaust note, particularly during high-load driving.

Depending on engine specification, installed headers and operating conditions, drivers may notice:

• A considerably louder exhaust tone at idle.
• A strong, aggressive flat-six sound during acceleration.
• Increased exhaust volume at higher engine speeds.
• More pronounced engine sound during downshifts.
• Significant cabin resonance.
• Noticeable low-frequency exhaust drone.
• A more direct motorsport-style exhaust character.

SOUL Valved Exhaust System.

The SOUL Performance Valved Exhaust System is a high-quality aftermarket sports exhaust upgrade specifically designed for Porsche 987.2 Boxster and Cayman models manufactured between 2009 and 2012.

Fits:

• Porsche Boxster 987 MKII 2.9L 2009-12
• Porsche Boxster S 987 MKII 3.4L 2009-12
• 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 exhaust system replaces the original rear exhaust assembly with a lighter, freer-flowing stainless steel system incorporating performance silencers, vacuum-operated exhaust valves, an X-pipe outlet and premium exhaust tips.

The Porsche 987.2 Boxster and Cayman are known for their responsive engines, balanced chassis and distinctive flat-six engine sound.

SOUL Performance developed this valved exhaust to enhance the driving experience by providing a deeper, fuller exhaust note while retaining the flexibility to switch between refined and aggressive sound characteristics.

Unlike a conventional non-valved sports exhaust, the SOUL system features two distinct operating modes.

With the exhaust valves closed, exhaust gases are directed through specially developed silencers containing high-quality sound-absorbing material. This produces a more controlled exhaust tone and is designed to minimise unwanted cabin drone, particularly during steady motorway driving.

With the valves open, exhaust gases follow a more direct route through the 2.5-inch pipework, producing a noticeably louder and more aggressive flat-six soundtrack.

The system incorporates perforated passages that allow exhaust pulses to interact with the silencers, helping create a fuller and more rounded sound even when the valves are open.

Manufactured from mandrel-bent T304L stainless steel, the exhaust is designed for durability, corrosion resistance and efficient exhaust gas flow.

The reinforced silencer casings and strengthened mounting brackets are engineered to withstand repeated thermal cycles, exhaust vibration and demanding driving conditions.

SOUL Performance states that its exhaust weighs approximately 30 lb, compared with 35 lb for the equivalent factory exhaust components, providing a weight saving of approximately 5 lb (2.2 kg).

A key advantage is its compatibility with vehicles both with and without factory Porsche Sport Exhaust (PSE).

On PSE-equipped vehicles, the SOUL exhaust can use the existing factory exhaust valve control arrangement.

For vehicles without PSE, SOUL includes a valve controller kit that allows the driver to operate the exhaust valves using a remote control.

The controller kit can also be installed on PSE-equipped vehicles to provide manual valve override.

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

Available options include 321 stainless steel exhaust tips and lightweight single-wall titanium tips.

Each system is quality-checked and fixture-tested before dispatch to ensure consistent installation fitment.

Designed as a direct bolt-on replacement for the compatible original rear exhaust, the kit includes installation instructions and specified mounting hardware.

Backed by SOUL Performance's lifetime warranty, subject to the manufacturer's terms, this Valved Exhaust System is an ideal upgrade for Porsche owners seeking improved exhaust sound, selectable driving characteristics, reduced weight and durable stainless steel construction.

What This Product Does:
The SOUL Performance Valved Exhaust System directs combustion gases through the rear exhaust while allowing the driver to change the exhaust gas flow path and resulting sound.

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

The SOUL exhaust then routes these gases through its stainless steel pipework and silencers before they exit through the rear exhaust tips.

The position of the exhaust valves determines the path taken by the gases.

Its main functions include:

• Directing exhaust gases: Carries combustion gases from the upstream exhaust components to the rear outlets.
• Providing selectable exhaust sound: Allows quieter and louder exhaust characteristics.
• Reducing unwanted drone: Uses sound-absorbing silencers to minimise low-frequency cabin resonance.
• Enhancing engine sound: Produces a deeper and more aggressive flat-six exhaust note.
• Supporting efficient exhaust flow: Uses mandrel-bent stainless steel tubing and a more direct open-valve flow path.
• Maintaining driver control: Allows the exhaust sound to be selected using the appropriate factory or supplied controller.
• Improving cruising refinement: Provides a quieter exhaust configuration for steady driving.
• Enhancing spirited driving: Delivers a stronger exhaust note during acceleration and high-RPM operation.
• Reducing exhaust weight: Offers a manufacturer-reported 5 lb saving over the original components.
• Maintaining durable construction: Uses corrosion-resistant stainless steel and reinforced mounting components.
• Enhancing rear-end styling: Offers different exhaust tip materials, styles and finishes.
• Supporting performance upgrades: Can complement compatible aftermarket exhaust headers.

Why Upgrading Matters:

1. Enhanced Flat-Six Exhaust Sound

The SOUL exhaust is designed to bring out more of the naturally aspirated Porsche engine's characteristic sound.

Drivers can enjoy a fuller and more aggressive exhaust note without permanently operating at maximum volume.

2. Selectable Exhaust Characteristics

The valved arrangement provides two different sound modes.

This makes the system more versatile than a permanently loud, non-valved exhaust.

3. Reduced Motorway Drone

The specially designed silencers help minimise unwanted low-frequency resonance.

SOUL specifically reports drone-free closed-valve motorway operation when combined with the original factory headers.

4. Improved Exhaust Flow Potential

The system uses mandrel-bent 2.5-inch over-axle pipework and a more direct exhaust path when the valves are open.

This is intended to support efficient exhaust gas movement.

5. Manufacturer-Reported Performance Improvements

SOUL Performance reports Dynojet testing on a Porsche 987.2 Cayman S fitted with its Valved Exhaust System and Long Tube Street Headers.

The manufacturer recorded maximum improvements of approximately:

8 wheel horsepower. 11 lb-ft of torque.

These gains were recorded around 4,100 RPM in the tested combined configuration.

Important: These figures should not be presented as guaranteed gains from the Valved Exhaust System alone.

6. Reduced Exhaust Weight

SOUL states that its Valved Exhaust System weighs approximately 30 lb compared with 35 lb for the factory components.

This represents a saving of approximately 5 lb (2.2 kg).

7. Compatibility with Factory PSE

Vehicles already equipped with Porsche Sport Exhaust can retain compatible factory-style valve operation.

The supplied SOUL controller can also offer manual override.

8. Valve Control for Non-PSE Vehicles

Vehicles without factory PSE can gain selectable exhaust sound using the supplied SOUL valve controller kit.

This is particularly useful for owners who want the versatility of a valved exhaust without an original factory PSE system.

9. Durable Stainless Steel Construction

The T304L stainless steel tubing offers corrosion resistance and durability under demanding exhaust operating temperatures.

10. Reinforced Exhaust Mounting

SOUL incorporates strengthened brackets and reinforced silencer casings.

These are designed to withstand repeated vibration and thermal cycling during road and track driving.

11. Premium Exhaust Tip Options

Owners can select different stainless steel and titanium exhaust tip styles.

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

12. Direct Bolt-On Installation

The system is designed for the original compatible mounting arrangement.

SOUL fixture-tests each exhaust and supplies the relevant installation instructions and hardware.

13. Manufacturer Lifetime Warranty

Ninemeister 9m 987.2 Sports Exhaust Valved Rear Silencer – Titanium

Transform the sound and driving experience of your Porsche 987.2 Boxster or Cayman with the Ninemeister 9m Titanium Valved Sports Exhaust.

Fits:

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

Manufactured from precision-welded aerospace-grade TC4 titanium, this lightweight rear silencer delivers a more distinctive sports car exhaust note while reducing weight by approximately 50% compared with the original Porsche silencer.

Its switchable valve system allows the driver to choose between a quieter exhaust setting for everyday driving and a louder, more engaging sound when desired.

What Does It Do?

The Ninemeister titanium sports silencer manages exhaust gas flow and sound as gases exit the engine.

Its X-pipe design allows exhaust gases from both cylinder banks to merge, producing a more distinctive exhaust character.

The integrated valves allow the driver to alter the exhaust sound at the push of a button, offering a quieter setting for relaxed driving and a louder, sportier tone when desired.

Why Upgrade to a Ninemeister Titanium Sports Exhaust?

The factory Porsche exhaust provides a balance of performance, comfort and noise control. The Ninemeister system offers a more sporting alternative without sacrificing everyday usability.

Advantages include:

• More pronounced flat-six engine sound
• Switchable exhaust valves for adjustable noise levels
• Approximately 50% reduction in rear silencer weight
• Improved throttle response claimed by Ninemeister
• Lightweight titanium construction
• Direct replacement without cutting or welding
• Choice of black or silver exhaust tips

The result is a more engaging driving experience with the flexibility to adjust the exhaust character to suit the journey.

What Are the Advantages of a Titanium Exhaust?

Titanium offers several benefits over conventional exhaust materials, particularly for performance-focused Porsche applications.

Reduced Weight – Titanium's low density allows a significant reduction in exhaust weight. The Ninemeister system weighs approximately half as much as the original silencer.

Improved Weight Distribution – Removing weight from the rear of the vehicle reduces overall mass and can provide a small benefit to handling responsiveness.

Corrosion Resistance – Titanium offers excellent resistance to corrosion, making it well suited to exhaust system applications.

Distinctive Sound – Titanium exhaust construction can produce a sharper, more metallic exhaust character compared with conventional systems.

High-Temperature Durability – TC4 titanium combines low weight with strength and durability suitable for demanding exhaust applications.

Why Choose a Valved Exhaust?

A valved sports exhaust provides greater control over exhaust sound than a conventional fixed-volume sports silencer.

With the valves in their quieter setting, the exhaust is better suited to normal driving. Switching to the louder setting produces a more pronounced sports exhaust note, allowing the driver to enjoy the character of Porsche's naturally aspirated flat-six engine.

This flexibility makes the Ninemeister system suitable for owners who want additional sound without a permanently loud exhaust.

Installation Notes

The Ninemeister 9m titanium silencer is designed as a direct bolt-on replacement for the factory rear exhaust assembly.

No cutting or welding is required.

Inspect the existing exhaust clamps, mounting brackets and associated hardware before installation. Ensure the exhaust valves and their control system operate correctly after fitting.

Ninemeister states that the system complies with emissions regulations and does not trigger an engine management warning light. Local road-noise requirements should still be checked.
