SOUL Performance Sport Cat Downpipes for 9YA Porsche Cayenne GTS / S / Turbo / Turbo S & Turbo GT
SOUL Performance’s Sport Cat Downpipes for 9YA Cayenne 4.0L TT models are large-diameter downpipes built around free-flowing catalytic converters for an industry-leading increase in turbo sound, throaty engine note, and crackles. SOUL pairs free-flowing, durable construction with precise fitment to sharpen response, increase flow, and deliver a more engaging exhaust note.
Development
- Looking to turn up the power, or turn heads? SOUL’s high-flow catalytic converters allow for great flow while minimizing the chances of a check engine light, and were engineered to support big power. The increased flow delivers better turbo response and a noticeable gain in drivability, with extra pops and turbo sound more befitting of a performance vehicle.
Construction
- Each downpipe is made from mandrel-bent .065in wall, 3in diameter T304L stainless steel tubing and CNC-cut flanges. All welds are back-purged for increased longevity under the most extreme conditions.
Bolt-On and Go
- Each set is built and tested in a fixture for guaranteed perfect fitment. Every set is rigorously quality-checked prior to shipping, then foam packed to arrive in perfect condition. New high-grade hardware is included to mate the downpipes to the exhaust.
