Fabspeed Audi R8 V8 Valvetronic Supersport X-Pipe Exhaust System (2007-2012)

Enjoy all the benefits of Fabspeed's world-renowned Supersport X-Pipe Exhaust System, now available with more power and sound at the push of a button!  Maximum gains of over 9whp and 12 ft/lbs of torque at 4,000 RPM with full V8 exhaust sound!                                               We wanted to craft a sensational exhaust for a brilliant car. Our engineers set out to unleash the full unmuffled roar of the 4.2L V8 while being able to retain civility around town when desired. VALVES CLOSED: Exhaust gases are channeled through Fabspeed's signature 63.5mm Quad-Resonated X-pipe. We engineered it specifically to smooth out exhaust pulses for a sophisticated, exotic, and distinctly European exhaust note while being as free flowing as possible. The tone is perfect for cruising around town or on long highway drives, with no droning at any RPM.  VALVES OPEN: Exhaust gases are free to flow straight from the engine unmuffled through 70mm dump tubes with a snarling aggressive scream.
