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.Â
VALVES OPEN: Exhaust gases are free to flow straight from the engine unmuffled through 70mm dump tubes with a snarling aggressive scream. The full fury of the 4.2L engine is unleashed, a thunderous and distinct V8 roar along with an intoxicating and menacing burble upon deceleration and bark when downshifting. In-cabin tone is fantastic with no drone, freely have a conversation as all heads on the block turn in your direction.   Â
 HELICAL VALVES:
We use Helical Valves for their unprecedented quality - which have been proven by many OEM manufacturers such as Porsche themselves, McLaren, Ferrari, Lamborghini, and many more.
Increased reliability - proven in racing and high volume OEM useÂ
High-temperature bearings at both ends of the butterfly spindle
