Over axle GPF delete pipes.

Ditch the factory gas particulate filters to increase power, save weight and add a throatier more aggressive tone. Our design process started with 3D scanning the entire exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing we settled on using a one piece mandrel bent over axle pipe that goes straight into the free flowing part of the OEM PSE exhaust and a secondary pipe TIG welded to the main section to make a Y configuration to utilize the quiet side of the PSE exhaust when the valves are closed.

SOUND: 
These Over Axle GPF Delete Pipes will bring out a stronger throatier tone from your 4.0l flat six. This is a mild but noticeable increase in overall volume over stock.

FEATURES:
•  Fits all 718 Cayman/Boxster GT4 / GTS / Spyder Cars 2020+
•    Over Axle pipes remove and delete the Gasoline Particulate Filters, GPF, found on all 4.0L cars worldwide

SOUL Competition Over Axle Pipes.

The SOUL Performance Competition Over-Axle Pipes are premium aftermarket performance exhaust components specifically designed for the Porsche 718 Cayman GT4 RS and 718 Spyder RS.

Fits:

• Porsche Boxster Spyder RS 718 4.0L 01/2019>>
• Porsche Cayman GT4 RS 718 4.0L  

Developed for Porsche's naturally aspirated 4.0-litre GT3-derived flat-six engine, these precision-engineered pipes replace the factory over-axle exhaust sections with a lighter, freer-flowing stainless steel configuration.

The original Porsche over-axle pipes incorporate secondary catalytic converters and particulate-filter housings. These components form part of the original exhaust configuration, which is designed around emissions requirements, packaging constraints and noise control.

SOUL Performance developed its Competition Over-Axle Pipes to eliminate these restrictions and improve the movement of exhaust gases through the system.

Unlike traditional round-tube exhaust replacements, the SOUL design uses specially shaped oval tubing to maintain a full 3-inch flow diameter throughout the pipework while providing sufficient clearance around the vehicle's suspension and body components.

This design allows a larger exhaust flow path to be accommodated within the limited space available above the rear axles.

The Competition Over-Axle Pipes are manufactured from mandrel-bent T304L stainless steel with a 0.065-inch wall thickness, providing strength, corrosion resistance and durability under repeated high-temperature operation.

What This Product Does:
The over-axle pipes form part of the exhaust system between the exhaust headers and the rear exhaust assembly.

Their primary function is to carry hot combustion gases from the engine's upstream exhaust components towards the rear silencers and tailpipes.

The SOUL Competition Over-Axle Pipes perform this function while providing a larger and less restrictive exhaust gas passage.

1. Direct Exhaust Gases

The pipes transport exhaust gases from the header outlets towards the rear exhaust system.

They form an essential connection between the engine's exhaust manifolds and the rear silencers.

2. Improve Exhaust Gas Flow

The full 3-inch flow path is designed to minimise unnecessary restrictions.

This allows exhaust gases to travel more freely through the over-axle sections.

3. Eliminate Secondary Catalytic Converter Restrictions

The Competition Over-Axle Pipes remove the factory secondary catalytic converters from this part of the system.

This reduces exhaust flow restriction but also removes part of the original emissions-control equipment.

4. Replace Particulate-Filter Housings

The original over-axle assemblies incorporate particulate-filter housings.

Their contents and monitoring arrangements vary according to vehicle market.

SOUL removes these housings entirely with its replacement pipes.

5. Enhance Exhaust Sound

Removing the original internal exhaust restrictions allows more of the engine's exhaust pulses and sound to travel into the rear exhaust.

The result is a noticeably louder and more aggressive flat-six soundtrack.

6. Support Engine Responsiveness

More efficient exhaust flow may help the engine respond more readily to accelerator input, particularly during high-load and high-RPM operation.

Actual performance changes depend on the vehicle's complete exhaust configuration and operating conditions.

7. Reduce Exhaust Weight

The replacement pipes provide a manufacturer-reported reduction of approximately 13.3 lb compared with the original assemblies.

8. Maintain Suspension Clearance

The specially developed oval tubing allows a large flow area to pass through the restricted space above the rear axles.

This design helps maintain clearance around the suspension and body components.

9. Reduce Heat-Retaining Exhaust Mass

Eliminating the original catalyst and filter housings reduces the amount of bulky exhaust material within the over-axle area.

Appropriate thermal management remains necessary.

10. Connect Factory or Performance Exhaust Components

The pipes allow compatible factory and aftermarket headers and rear exhaust systems to be joined through a performance-focused over-axle arrangement.

Why Upgrading Matters:

1. Improved Exhaust Gas Flow

The full 3-inch exhaust flow path provides a less restrictive route for gases travelling between the headers and rear exhaust.

This supports improved exhaust efficiency.

2. Significant Exhaust Sound Enhancement

The Competition Over-Axle Pipes are designed to produce one of the most substantial exhaust sound changes available from a single component.

They allow more of the Porsche 4.0-litre flat-six engine's character to be heard.

3. Reduced Exhaust Restriction

Removing the factory secondary catalytic converters and filter housings reduces internal restrictions.

This allows exhaust gases to travel more directly towards the rear exhaust.

4. Reduced Exhaust Weight

SOUL reports a saving of approximately 13.3 lb (6 kg) compared with the original over-axle pipe assemblies.

Reducing unnecessary weight is beneficial in performance-focused vehicle preparation.

5. Motorsport-Focused Construction

The mandrel-bent stainless steel tubing, precise flanges and high-quality welding are designed for demanding operating conditions.

6. Enhanced Engine Responsiveness

Improved exhaust flow may support sharper engine response and more effective high-RPM operation.

No universal numerical horsepower or torque improvement is guaranteed for these pipes alone.

7. Optimised Pipe Geometry

The specially developed oval sections allow SOUL to maintain a large exhaust flow area while accommodating the restricted packaging space above the rear axles.

8. Durable Stainless Steel

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

9. Reduced Factory Exhaust Heat Retention

The simpler pipework eliminates bulky factory catalyst and filter housings.

However, SOUL strongly recommends thermal wrapping or another suitable heat management solution.

10. Compatible with Other Exhaust Upgrades

The pipes are designed to work with compatible factory or upgraded headers and rear exhaust systems.

This makes them suitable for a range of performance exhaust configurations.

11. Precision-Manufactured Fitment

Waterjet-cut flanges and dedicated fabrication fixtures support accurate installation and consistent component alignment.

12. Direct Bolt-On Installation

The pipes are designed to replace the corresponding original over-axle assemblies without fabrication when fitted to a compatible vehicle.

13. Manufacturer Lifetime Warranty

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