Combining our free-flowing Over Axle Pipes with our Valved Exhaust System eliminates the major bottlenecks in the GT4 RS exhaust flow and extracts the most sound and performance potential for the platform, but still allows for comfortable cruising with the valves closed. Owing to the unique oval design of our Over Axle Pipes and the Valved Exhaust’s x-pipes, this system runs a full 3 inches all the way through, ensuring that the 4.0-liter flat-six realizes its motorsports pedigree in every way.

Exhaust Tip Selection:

For those looking to maintain the factory appearance, this system can be used with OEM exhaust tips. However, please note that the OEM tips feature a much smaller diameter inlet, requiring the system to be necked down, which introduces a restriction and reduces overall performance. To extract the most from your GT4 RS, we strongly recommend selecting our high-performance exhaust tips, designed to complement the full 3-inch system without any compromises.

DETAILS:

  • Fits Porsche 718 GT4 RS / Spyder RS with factory or upgraded headers
  • No check engine light on North American cars, ECU tuning required for European cars
  • All SOUL Performance Products exhaust components are backed by the industry’s first and finest Lifetime Warranty for both street and track use
  • Designed and built in-house at our Willow Grove, PA facility

NOTE:

Because of the increased output of the GT3-derived engine in 718 RS models, and the additional heat generated as a result, we strongly recommend applying a thermal management solution to Over Axle Pipe products to protect nearby components and body parts. We offer an efficient and effective wrapping solution in-house.

ECU tuning is the process of adjusting the engine control unit's software to enhance vehicle performance, efficiency, or fuel economy.

It can, depending on the manufacturer. Many warranties do not cover modifications like ECU tuning.

Use the highest octane fuel recommended for your specific tune to ensure optimal performance and safety.

Yes, a properly tuned car can be used daily, as long as the tune is tailored for reliable, everyday driving.

CPC (Central Powertrain Controller) and TCU (Transmission Control Unit) manage your vehicle's powertrain and transmission systems, respectively.

Map switching allows you to change between different tuning settings (maps) for varying driving conditions without having to retune the ECU.

Yes, if done by a professional using proper tools, ECU tuning is generally safe for your vehicle.

ECU tuning works by modifying the software that controls engine parameters like fuel mixture, ignition timing, and boost pressure to optimize performance.

The process of installing a tune depends on the vehicle’s make and model. Some tunes are installed by connecting a tuning device to your car’s OBD-II port and uploading the tuned software, others may require ECU unlock.

Stage 1 is for vehicles with no modifications, stage 2 is for vehicles with bolt-on upgrades or downpipes installed.

We offer post-installation support, troubleshooting, and guidance on using your tuning software and hardware.

Choose tuning software that is compatible with your vehicle, has good reviews, and suits your performance goals (e.g., reliability vs. max power).
