Porsche Cayenne Turbo S / GT / GTS – EPA-Compliant 400 Cell Catted Downpipes
Precision Engineered for the 4.0L Twin-Turbo V8 • High-Flow Performance •
Introducing Our NEW 400 Cell EPA-Compliant Downpipes for Cayenne
The Porsche Cayenne Turbo platform is a masterclass in performance engineering. However, factory catalyst restrictions limit the full efficiency and character of its 4.0L twin-turbo V8. Our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce exhaust restriction, improve turbo response, and refine the exhaust note — all while maintaining emissions compliance standards.
Designed specifically for the Cayenne Turbo S, Turbo GT, and GTS, these downpipes elevate the driving experience while preserving the precision Porsche is known for.
