Product Description

 

 

The Fabspeed Valvetronic Supersport X-Pipe Exhaust System is the ultimate exhaust solution for the Porsche 991 Turbo and Turbo S, delivering both maximum performance and complete control over exhaust tone. By replacing the restrictive factory mufflers and catalytic converters with a high-flow X-pipe and valved design, this system unlocks significant horsepower, torque, and throttle response gains across the entire powerband. 

What sets this system apart is its dual-character functionality. With the valves closed, exhaust gases are routed through a quad-resonated X-pipe for a refined, controlled tone ideal for daily driving. Open the valves, and the system bypasses restrictions entirely—producing an aggressive, GT2 RS-inspired exhaust note with sharp crackles and a raw turbocharged flat-six sound.

Engineered with premium materials and motorsport-grade components, this system is designed to deliver both reliability and performance. Whether you're building a high-horsepower street car or looking for a more engaging driving experience, this is one of the most transformative upgrades available for the 991 Turbo platform.
