01. -The beauty of this kit is its simplicity. The new tailpipe, muffler, and tip clamp right behind the existing stock turbo's down and front pipes. The primary responsibility of the new hardware is to reduce the amount of exhaust backpressure and cool the exhaust turbine outlet temperature, as well as increase the flow of the exiting air. Backpressure restricts the output of exhaust, causing more power to be absorbed rather than utilized. A larger pipe allows more air to exit, as well as enter, the engine.
