Valved Catback Exhaust for Porsche Cayenne Turbo / Turbo S (958) (2011–2018)

This valved catback exhaust system allows you to switch anytime between quiet OEM-style refinement and a loud, deep, performance-focused V8 tone. Constructed from high-grade 304 stainless steel with precision TIG welding, it offers excellent durability, corrosion resistance, and a clean premium finish suitable for a high-performance luxury SUV. The system is fully bolt-on with no cutting or welding required, making installation straightforward at most professional exhaust shops. Designed specifically for the 4.8L V8 twin-turbo engine in the 958-generation Cayenne Turbo and Turbo S, it improves exhaust flow and throttle response while delivering a fuller, stronger, and more aggressive sound when the valve is open, yet maintaining refined comfort when closed.

Fitment: Compatible with Porsche Cayenne Turbo and Turbo S (958 / 958.1 / 958.2, 2011–2018) equipped with the 4.8L V8 twin-turbo engine. Fitment can be confirmed using VIN or a rear exhaust photo.
