Piper mild steel performance rear boxes are designed to fit to the standard factory OE exhaust system. All Piper mild steel rear boxes come with a 12 month warranty. The Piper performance back boxes are designed to be less restrictive and therefore release a moderate power gain of approx 5%. You will also benefit from a slightly deeper exhaust tone and there are numerous tailpipe designs to choose from. Awesome power, awesome noise, awesome looks!
