Enhance the performance and sound of your Porsche 718 GT4 RS or Spyder RS with the SOUL Resonated Over Axle Pipes, engineered to deliver a more refined, aggressive tone while reducing weight and improving exhaust flow. By eliminating the factory secondary catalytic converters and unused particulate filter chambers, these pipes optimize the flow path and reduce heat retention, unlocking the true potential of the GT3-derived engine.
Unlike traditional designs, SOUL’s solution utilizes full 3-inch diameter tubing from flange to flange and transitions into oval-shaped piping to accommodate the tight clearances within the car’s suspension and body. This thoughtful engineering ensures consistent flow without compromise, while the integrated resonators help smooth out and moderate the sound profile compared to SOUL’s Competition option.
Constructed from high-grade T304L stainless steel with precision TIG welding and ISO-certified flanges, each unit is handcrafted and quality-checked in-house in the USA. These pipes not only improve acoustic character but also offer substantial weight reduction over the OEM components, enhancing both performance and handling response.
SOUL also offers in-house thermal wrapping solutions to protect nearby components from additional heat produced by the RS powertrain. For optimal results and durability, thermal management is strongly recommended for RS applications.
