Porsche 987.1 Cayman / Cayman S - 2005 to 2008

Ideal for enthusiasts seeking a more conservative sound enhancement, this muffler is particularly suited for those running cat bypass or sport cats who want to avoid excessive noise levels. At low RPMs and during cruising, it delivers a refined, deep tone that remains discreet. Designed to comply with Germany's stringent urban decibel regulations, this is a German Edition muffler built for subtle performance.

DesignTek offers a wide selection of mufflers to suit diverse preferences, ranging from mild, street-friendly options to exotic-sounding sport mufflers and high-intensity race mufflers. The DesignTEk Edition 987.1 street muffler stands apart from conventional aftermarket designs.

Crafted from German V2A - X5CrNi18-10 - 1.4301 (T-304 L) lightweight stainless steel, it incorporates advanced features like double perforated sound absorption tubes in a trapezoidal pattern with variable perforation diameters. This design effectively isolates and dampens unwanted drone frequencies. Additional stamped ribbing on the outer shell further reduces unwanted resonance, achieving superior acoustic performance.
Unlike traditional baffle plates, this design minimizes back pressure, particularly at higher gas velocities, resulting in improved throttle response and enhanced performance across the rev range. When combined with software tuning, upgraded intakes, or additional exhaust modifications, the benefits are even more pronounced.

This muffler offers a subtle factory motorsport sound, making it an excellent choice for those who desire a conservative sport tone. Its reduced decibel output ensures it remains suitable for vehicles equipped with sport cat or cat bypass headers, maintaining an enjoyable sound without becoming overly loud.

Each system undergoes rigorous testing for exhaust gas flow, thermal durability, resistance to cracking, and long-term reliability, ensuring exceptional quality and performance.

Features:

  • Increases by 9 HP and 11 TQ
  • Weighs 43 lbs. (19.5 Kg)
  • German V2A - X5CrNi18-10 - 1.4301 (T-304 L) stainless steel for improved durability
  • Includes dual round 3.5” (90mm) tips
  • Direct bolt on replacement

SOUL Performance Exhaust System.

The SOUL Performance Exhaust System is a premium aftermarket stainless steel sports exhaust developed specifically for Porsche 987.1 Boxster and Cayman models manufactured between 2005 and 2008.

Fits:

  • Porsche Boxster 987 2.7L 2005-08/08
  • Porsche Boxster 987 S 3.2/3.4L 2005-08/08
  • Porsche Cayman 2.7L 987C 2006-08
  • Porsche Cayman S 3.4L 987C 2005-08  


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.
  • Minimising cabin drone: Uses specially designed silencers to reduce unwanted low-frequency resonance.
  • Maintaining cruising refinement: Provides a more restrained exhaust note at steady engine loads.
  • Reducing exhaust weight: Offers an approximately 15 lb manufacturer-reported weight saving.
  • Supporting durability: Uses corrosion-resistant stainless steel and strengthened mounting components.
  • Maintaining exhaust alignment: Provides reinforced brackets designed to secure the exhaust during normal and demanding driving.
  • Improving rear-end styling: Allows owners to choose different exhaust tip materials and finishes.
  • Supporting performance modifications: Can be combined with suitable aftermarket exhaust headers.
  • Simplifying operation: Provides sporting exhaust sound without electronic or vacuum-operated valves.



Exhaust Sound Characteristics:
Normal Driving – Refined Sporting Tone

During gentle acceleration and steady cruising, the system is designed to maintain a controlled exhaust sound.

Benefits include:

  • A deeper flat-six exhaust tone.
  • Reduced unwanted cabin resonance.
  • More refined motorway driving than a typical race exhaust.
  • Consistent exhaust operation without valve controls.
  • A sporting sound without continuously excessive volume.

Acceleration – Aggressive Flat-Six Sound

Under heavier throttle, the exhaust produces a more pronounced soundtrack.

Drivers can expect:

  • A stronger exhaust note during acceleration.
  • More noticeable flat-six engine character.
  • Greater sound intensity at higher engine speeds.
  • A more engaging sound during gear changes and downshifts.
  • Increased exhaust character compared with the original rear silencers.

The final sound will depend on the original or aftermarket exhaust headers fitted to the vehicle.



Why Upgrading Matters:

1. Enhanced Flat-Six Engine Sound

The SOUL Performance Exhaust produces a deeper, fuller and more aggressive sound than the original rear exhaust assembly.

It is designed to highlight the character of the Porsche flat-six engine without the excessive noise associated with some motorsport exhausts.

2. Reduced Unwanted Drone

The performance silencers are specifically developed to minimise unwanted cabin resonance.

This makes the system appealing to owners who want an engaging exhaust note without consistently high noise levels.

3. Improved Exhaust Flow Potential

The system uses smooth, mandrel-bent stainless steel tubing and replaces the factory rear exhaust configuration.

This is intended to reduce unnecessary exhaust restriction.

4. Lightweight Construction

SOUL Performance reports the following weight comparison:

Factory rear exhaust: approximately 36.6 lb (16.6 kg). SOUL Performance Exhaust: approximately 21.7 lb (9.8 kg). Weight saving: approximately 15 lb (6.8 kg).

Reducing unnecessary vehicle weight can be beneficial in performance-focused applications.

5. Stainless Steel Durability

T304L stainless steel provides corrosion resistance and durability under high-temperature operating conditions.

6. Reinforced Exhaust Mounting

The strengthened brackets and fortified silencer casings are designed to resist fatigue damage caused by vibration and repeated thermal cycling.

7. No Exhaust Valve Maintenance

Because this system is non-valved, there are no exhaust valve actuators, vacuum-control hoses or electronic switching mechanisms associated with the replacement exhaust itself.

8. More Engaging Driving Experience

The stronger exhaust sound makes the engine's response more noticeable during acceleration and gear changes.

9. Compatibility with Aftermarket Headers

SOUL designed the exhaust to work with compatible aftermarket exhaust headers.

The manufacturer specifically highlights the system's controlled sound characteristics when used with its performance header configurations.

10. Premium Exhaust Tip Options

Owners can choose from different stainless steel exhaust tip finishes or select lightweight titanium tips.

11. Direct Bolt-On Installation

The exhaust is designed to fit the compatible original mounting arrangement.

SOUL fixture-tests each system and supplies fitting instructions and relevant hardware.

12. Manufacturer Lifetime Warranty

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

Ninemeister 9m 987.1 Sports Exhaust Valved Rear Silencer – Titanium

Give your Porsche 987.1 Boxster or Cayman a more distinctive exhaust note while significantly reducing weight with the Ninemeister 9m Titanium Valved Sports Exhaust.

Fits:

  • Porsche Boxster 987 2.7L 2005-08/08
  • Porsche Boxster 987 S 3.2/3.4L 2005-08/08
  • Porsche Cayman 2.7L 987C 2006-08
  • Porsche Cayman S 3.4L 987C 2005-08  


Precision-welded from high-grade TC4 titanium, this performance rear silencer is approximately 50% lighter than the original Porsche exhaust. Its X-pipe configuration produces a more engaging flat-six engine sound, while the switchable valves provide the flexibility to select between quieter everyday driving and a louder sports exhaust note.

Designed as a direct replacement for the factory rear silencer, it offers an effective upgrade without cutting or welding.

What Does It Do?

The Ninemeister titanium rear silencer replaces the original exhaust muffler, changing how exhaust gases flow and how the engine sounds.

Its X-pipe arrangement allows exhaust pulses from both cylinder banks to interact, creating a more pronounced flat-six exhaust character.

The integrated valves provide control over the exhaust volume, allowing the driver to switch between a more subdued sound and an enhanced sports exhaust tone.

Why Upgrade to a Ninemeister Sports Exhaust?

The standard Porsche exhaust is designed to provide quiet, comfortable operation while meeting factory noise requirements.

The Ninemeister system is aimed at owners who want a more exciting driving experience, greater exhaust character and less weight.

Advantages include:

  • A deeper, more engaging flat-six exhaust note
  • Adjustable sound through the valved exhaust system
  • Approximately 50% reduction in rear silencer weight
  • Improved throttle response claimed by Ninemeister
  • Lightweight titanium construction
  • Enhanced sports exhaust character during acceleration
  • Direct-fit installation using the original mounting arrangement

What Are the Advantages of a Titanium Exhaust?

Titanium is widely used in high-performance exhaust systems because it combines strength with exceptionally low weight.

Reduced Weight – The Ninemeister titanium silencer weighs approximately half as much as the original exhaust, reducing unnecessary weight at the rear of the vehicle.

Handling Benefits – Lower vehicle weight can contribute to improved responsiveness, particularly during changes of direction.

Corrosion Resistance – Titanium naturally resists corrosion, offering excellent durability against moisture and environmental exposure.

Distinctive Exhaust Sound – Titanium construction can produce a sharper, more metallic exhaust character, complementing the naturally aspirated Porsche flat-six engine.

Strength and Durability – TC4 titanium provides a strong, lightweight material suitable for demanding exhaust applications.

Why Choose a Valved Exhaust System?

A valved exhaust offers the benefits of a sports silencer without requiring the driver to accept a permanently louder exhaust.

With the valves in their quieter setting, the system provides a more restrained sound for everyday driving.

Opening the valves creates a stronger exhaust note, allowing the engine's character to become more noticeable during acceleration.

This makes the Ninemeister system particularly appealing for Porsche owners who use their cars for both regular road driving and enthusiastic weekend motoring.

Installation Notes

The Ninemeister 9m titanium sports silencer is designed to bolt directly into the original rear exhaust mounting position.

No cutting or welding is required.

Inspect the exhaust clamps, mounting brackets and connecting hardware before fitting. Ensure the valve control arrangement is correctly installed and functioning after assembly.

Ninemeister states that the system maintains emissions compatibility and does not trigger an engine management warning light. Compliance with local vehicle noise regulations should be confirmed.

Ninemeister 9m Porsche 987.1 Boxster & Cayman Titanium Sports Exhaust Upgrades

The Porsche 987.1 Boxster and Cayman are known for their naturally aspirated flat-six engines and engaging driving characteristics. Upgrading the factory rear silencer provides an opportunity to enhance the exhaust sound while reducing weight.

The Ninemeister 9m titanium valved sports exhaust combines lightweight TC4 titanium construction, an X-pipe design and adjustable exhaust valves. With approximately 50% less weight than the original rear silencer, it offers a performance-focused alternative for Porsche 987.1 owners seeking improved exhaust character and a more involving driving experience.
