Product Description

 

 

Unlock the sound and performance potential of the Porsche 718 GT4 RS and Spyder RS with the SOUL Performance Sport Cat Over Axle Pipes. Designed to replace the restrictive factory over axle pipe assemblies, these high-flow pipes eliminate the unnecessary particulate filter restriction found on North American vehicles while retaining a monitored high-flow catalytic converter. The result is improved exhaust flow, increased sound intensity, sharper throttle response, and a more motorsport-inspired character from the GT3-derived 4.0L naturally aspirated flat-six engine. Unlike a full catless setup, the SOUL Sport Cat Over Axle Pipes provide a performance-focused solution while maintaining catalytic converter functionality for a more street-friendly upgrade. Manufactured in-house in the USA from premium T304L stainless steel and engineered for perfect OEM fitment, this upgrade is the ideal next step for GT4 RS and Spyder RS owners looking to enhance their exhaust system without compromising drivability.
