RS Barn has developed a bolt on 968 Cat-Back exhaust system to improve Power, Torque and Sound. The exhaust system poduces a mellow Euro sound. Quiet enough to cruize around the neighborhood but agressive during spirited romps. Along with stage 1 chip, the exhaust pushes the torque band down almost 1000 rpm. No more waiting till 4400 rpm for a kick in the pants. You feel a strong surge starting at 2800 to 3000 rpm that continues to build to redline. Dynojet tests have show gains of 18 Ft/Lbs torque and 12 HP gains. Beatifull 4.5" oval tip exits in stock location.
