SOUL Race Exhaust System, PDK Transmission. Porsche 987.2 Boxster / Cayman › POR.9872P.RER.

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  

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.
• Reducing vehicle weight: Saves approximately 19 lb compared with the manufacturer's stated original exhaust and bracket weight.
• Supporting track durability: Uses reinforced mounting components and high-quality fabrication.
• Reducing mounting stress: Employs a bespoke transmission brace, heavy-duty clamps and vibration dampeners.
• Accommodating modified suspension: Uses over-axle pipe profiles designed to maintain clearance around nearby suspension components.
• Supporting repairability: Incorporates mounting components intended to be serviceable following damage.
• Maintaining exhaust alignment: Provides a secure mounting arrangement for demanding driving conditions.
• Supporting performance modifications: Connects to compatible factory or SOUL Performance exhaust headers.
• Providing corrosion resistance: Uses T304L stainless steel construction.
  
  

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.

1. Significant Weight Reduction

SOUL reports a saving of approximately 19 lb (8.6 kg) compared with the factory exhaust components, including mounting brackets.

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

2. Motorsport-Focused Durability

The reinforced mounting arrangement and high-quality fabrication are designed to withstand repeated circuit use.

This makes the system relevant to Porsche owners preparing their vehicles for demanding track applications.

3. Improved Exhaust Flow Potential

The Race Exhaust uses mandrel-bent stainless steel tubing and a more direct gas path.

This is intended to reduce unnecessary restriction in the rear exhaust.

4. Aggressive Flat-Six Sound

The system provides a substantially louder exhaust note than the original Porsche rear exhaust.

It emphasises the naturally aspirated engine's sound during acceleration and high-RPM operation.

5. Reduced Mounting Stress

The bespoke transmission mounting brace, Mikalor clamps and rubber dampeners help manage vibration and mechanical movement.

6. Improved Serviceability

SOUL designed the mounting components to be easier to repair or replace in the event of track damage.

7. Suspension Clearance

The over-axle pipe profiles are designed to provide clearance around the rear axles and anti-roll bar drop links.

This can be beneficial on lowered or modified vehicles, although actual clearance must always be checked.

8. Stainless Steel Construction

T304L stainless steel provides corrosion resistance and durability under repeated high-temperature operation.

9. Precision Fabrication

The exhaust incorporates TIG-welded brackets and back-purged weld construction.

These manufacturing processes are intended to support consistent quality and durability.

10. Direct Bolt-On Installation

The system is designed to fit the compatible original exhaust connection points.

SOUL fixture-tests each exhaust before dispatch and includes fitting instructions.

11. Manufacturer Lifetime Warranty

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