SOUL Competition Exhaust Package, Black Chrome Tips. Porsche 987.2 Boxster / Cayman › POR.9872.COPKG.BC

SOUL Competition Exhaust Package, Black Chrome Tips (Chrome Dual Wall)

The SOUL Performance Competition Package is a premium aftermarket performance exhaust upgrade 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  

Exhaust Package Includes:

• Valved Exhaust System
• Competition Headers

Developed for Porsche's naturally aspirated 2.9-litre and 3.4-litre flat-six engines, this complete exhaust package combines SOUL Competition Headers with the manufacturer's Valved Exhaust System.

The package replaces the original exhaust manifold and catalytic converter assemblies, together with the factory rear exhaust, to provide a high-flow stainless steel exhaust arrangement.

Unlike the SOUL Street Package, which incorporates high-flow catalytic converters, the Competition Package uses catalyst-free exhaust headers. This reduces exhaust restriction and creates a more direct path for gases leaving the engine.

The Competition Headers feature 2-inch primary runners, port-matched mounting flanges, smooth-radius tubing and optimised exhaust collectors.

These design features are intended to improve exhaust scavenging, reduce unnecessary turbulence and enhance the engine's responsiveness.

The accompanying SOUL Valved Exhaust System uses mandrel-bent T304L stainless steel tubing, reinforced performance silencers, vacuum-operated exhaust valves and an X-pipe outlet arrangement.

The valved design provides two distinct exhaust sound characteristics.

With the valves closed, exhaust gases pass through specially developed sound-absorbing silencers, producing a deeper and more controlled exhaust tone. This arrangement is designed to minimise unwanted cabin drone during steady driving.

With the valves open, the exhaust gases follow a more direct route, producing a louder, more aggressive flat-six soundtrack.

The system is designed to suit vehicles with or without factory Porsche Sport Exhaust (PSE). The SOUL valve controller supplied with the valved exhaust allows selectable operation on compatible non-PSE vehicles and can provide manual override functionality on appropriately equipped PSE vehicles.

Manufactured from corrosion-resistant stainless steel, the package is engineered to withstand repeated thermal cycling, exhaust vibration and demanding performance driving.

SOUL Performance reports dynamometer testing on a 987.2 Cayman S equipped with PDK transmission, achieving a maximum improvement of 9 wheel horsepower and 10 lb-ft of torque at approximately 4,100 RPM.

The manufacturer has also track-tested the combination on its Project Cayman R.

The package is designed for direct bolt-on installation, with the components checked in fitting fixtures before dispatch.

Backed by the manufacturer's lifetime warranty, subject to its terms, the SOUL Competition Package is intended for Porsche owners seeking improved exhaust flow, a more engaging engine response and an aggressive, selectable exhaust soundtrack.

What This Product Does:
The Competition Package replaces major sections of the original exhaust system to improve the movement of combustion gases and allow the driver to select different exhaust sound characteristics.

The package consists of two principal components.

1. SOUL Performance Competition Headers

The Competition Headers collect exhaust gases as they leave the cylinder heads.

They replace the original exhaust manifolds and catalytic converter assemblies with stainless steel headers designed to reduce exhaust restriction.

Their main functions include:

• Collecting exhaust gases: Direct spent combustion gases away from the engine's cylinder heads.
  
• Improving exhaust flow: Use smooth-radius pipework and optimised collectors to reduce unnecessary restrictions.
  
• Supporting exhaust scavenging: Encourage efficient movement of exhaust pulses through the primary runners.
  
• Reducing exhaust backpressure: Remove the factory catalytic converters from the primary exhaust path.
  
• Supporting throttle response: Help the engine respond more efficiently to accelerator input.
  
• Increasing performance potential: Provide a freer-flowing exhaust arrangement for the naturally aspirated flat-six.
  
• Enhancing exhaust sound: Allow more of the engine's original exhaust character to pass into the rear system.
  
• Reducing weight: Replace the heavier factory manifold and catalyst assemblies with stainless steel performance headers.

The 2-inch primary runners and optimised collectors are designed for the characteristics of the 987.2 engine family.

2. SOUL Performance Valved Exhaust System

The Valved Exhaust System receives gases from the headers and directs them towards the rear exhaust outlets.

Its main functions include:

• Providing selectable quiet and aggressive exhaust sound modes.
• Reducing unwanted resonance with the valves closed.
• Producing a louder exhaust note with the valves open.
• Supporting efficient exhaust flow through mandrel-bent pipework.
• Providing an X-pipe outlet arrangement.
• Maintaining compatibility with the relevant PSE or supplied valve-control system.
• Supporting secure exhaust mounting through reinforced components.
• Enhancing the vehicle's rear appearance with premium exhaust tips.

 
Exhaust Sound Characteristics:

Valves Closed – Controlled Exhaust Tone

With the valves closed, exhaust gases pass through the SOUL performance silencers.

These contain sound-absorbing materials designed to reduce low-frequency resonance and control exhaust volume.

Benefits include:

• A deeper, more restrained flat-six exhaust note.
• Reduced cabin drone compared with open-valve operation.
• A more controlled sound during steady driving.
• Greater flexibility than a permanently unrestricted exhaust.

Valves Open – Motorsport-Inspired Sound

With the exhaust valves open, gases follow a more direct route through the performance exhaust.

This produces a much stronger exhaust note, particularly during acceleration and high-RPM operation.

Drivers may notice:

• A louder, more aggressive flat-six soundtrack.
• Greater sound intensity during acceleration.
• A more pronounced exhaust note during downshifts.
• Stronger engine character at higher RPM.
• A distinctive motorsport-inspired tone.

The final sound depends on engine specification, valve operation and driving conditions.

Track Noise Note: The system may exceed the sound restrictions imposed by some circuits and track-day organisers. Actual noise levels should be measured on the completed vehicle.

Why Upgrading Matters:

Improved Exhaust Flow

The Competition Headers use smooth-radius runners, port-matched flanges and optimised collectors.

By removing the factory catalytic converters, the system reduces exhaust restriction and supports more efficient exhaust gas movement.

Increased Performance Potential

SOUL Performance reports Dynojet testing on its Cayman S with PDK transmission.

The manufacturer recorded maximum gains of:

9 wheel horsepower. 10 lb-ft of torque.

These improvements were recorded at approximately 4,100 RPM in the tested configuration.

Results depend on the engine, vehicle condition, exhaust configuration and testing conditions. They are not guaranteed gains for every Boxster or Cayman.

Sharper Throttle Response

The freer-flowing exhaust arrangement is designed to support quicker and more consistent engine response during acceleration.

Enhanced Flat-Six Exhaust Sound

The Competition Headers and Valved Exhaust System work together to produce a stronger and more distinctive exhaust note.

The catalyst-free construction increases the amount of engine sound passing through the exhaust.

Selectable Exhaust Characteristics

Unlike a fixed competition exhaust, the SOUL valved arrangement allows the driver to select between more controlled and more aggressive exhaust sound modes.

Weight Reduction

SOUL reports that the Competition Headers weigh approximately 19 lb, compared with 26 lb for the factory manifold and catalyst assemblies, excluding hardware.

This represents a manufacturer-reported saving of approximately 7 lb (3.2 kg) for the headers.

The separately listed Valved Exhaust System also offers weight-saving potential compared with the original rear exhaust.

These component-specific figures should not be presented as a verified total package weight saving without confirmation.

Durable Stainless Steel Construction

T304L stainless steel offers corrosion resistance and durability under repeated thermal expansion and contraction.

The exhaust also incorporates reinforced silencer casings and mounting components.

Compatibility with Factory PSE

The Valved Exhaust System is designed to operate with the appropriate factory Porsche Sport Exhaust valve controls.

Valve Control for Non-PSE Vehicles

The supplied SOUL controller allows compatible vehicles without factory PSE to gain selectable exhaust valve operation.

Premium Exhaust Tip Options

The package offers a choice of stainless steel and titanium exhaust tips in different styles and finishes.

Complete Integrated Upgrade

Combining the Competition Headers and Valved Exhaust System provides an integrated exhaust solution developed by the same manufacturer.

Manufacturer Lifetime Warranty

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