Product details

The Fabspeed Center Muffler Bypass replaces the central silencer on the 2010–2011 Porsche 997.2 GT3 and GT3 RS. Its connecting talk-pipe joins exhaust pulses from the two banks, while the simplified two-bolt mounting arrangement supports a center-section-only conversion. From Fort Washington, Pennsylvania, Fabspeed Motorsport develops Porsche and other sports-car exhausts, intakes and ECU software through dyno testing, road use and racetrack evaluation.
