SOUL Performance Sport Catalyst Over Axle Pipes for 982 Porsche 718 GT4 RS / Spyder RS

The SOUL Performance Sport Cat Over Axle Pipe uses high-flow catalytic converters to deliver measurable sound and performance gains by replacing the empty particulate-filter section in the factory components. When combined with SOUL Performance Competition Headers, it provides a substantial increase in output and exhaust character while retaining a monitored catalytic converter to address emissions-related concerns. To manage the additional heat produced by the catalytic core, every SOUL Performance Sport Cat Over Axle Pipe is supplied with a heat management solution as standard.

Development

Construction

• Each set is assembled in-house in the USA by SOUL Performance using mandrel-bent, thick-wall 0.065-inch T304L stainless steel. Back-purged TIG welding with ARCAL Prime argon gas promotes proper weld penetration and long-term durability. Water-jet cut flanges are produced to ISO 9001:2015 standards with +/- 0.003-inch tolerances for exceptional precision. SOUL Performance fabricates these over axle pipes using thick-gauge aluminum fixtures that act as heat sinks during welding to prevent warping and help ensure consistent, accurate fitment.

Bolt on and Go

• Every set is rigorously quality-checked by SOUL Performance, test-fit in a dedicated fixture to confirm proper fitment, then foam packed to help ensure it arrives in perfect condition. New high-grade installation hardware is included.
