Fabspeed Valvetronic Supersport X-Pipe Exhaust System for Porsche 991

Description

Fabspeed's 991 Turbo Valvetronic Supersport X-Pipe Exhaust System replaces the restrictive OEM rear mufflers and catalytic converters for a deeper, throatier exhaust note along with improved power and throttle response. With valves open, unleash a bold roar from your 991 Turbo.

From the factory, Porsche equipped the 991 Twin Turbo models with an extremely powerful 3.8 L flat-6 engine setting a performance benchmark yet again for sports-cars and super-cars around the world. Despite the impressive performance, the soundtrack is decidedly lackluster without any indication as to the sheer power of the engine that fuels the fire. The exhaust note is far too sedate to be representative of a proper sports car. It was our mission to develop an exhaust system that was capable of retaining a valved system for the ultimate balance between street, and track exhaust tones.

Our engineers have spent countless hours of hands on development with the Fabspeed Valvetronic Supersport X-Pipe Exhaust System to extract the absolute best of both mild and wild exhaust notes from the 991 Turbo. The results speak for themselves.

Valves Closed: Enjoy our signature Supersport exhaust sound. Exhaust flow is channeled through Fabspeed's signature 63.5mm Quad-Resonated X-pipe. We engineered it specifically to smooth out exhaust pulses for a sophisticated and exotic exhaust note while being as free flowing as possible. The tone is perfect for cruising around town or long highway drives.

Valves Open: At the push of a button, the valves are opened and the exhaust is free to rocket straight out from the Sport Cats with an aggressive scream. The full story of Porsche's turbocharged 3.8 L flat-6 is unleashed, along with an intoxicating barrage of crackles and pops upon deceleration and downshifting. This system truly needs to be heard and felt in person to be appreciated.
