Description
This exhaust system was designed with one thing in mind, winning races! The RS-4 is a unique design with predicated power, a side benefit of a quiet, earthy exhaust note that speaks volumes for performance, and offers increased horsepower and torque. It features a Poly-resonant duplex chamber, a two-staged stepped baffle and an innovative carbon cone end-cap.
This Slip-On comes with a stainless steel tail-pipe, installation hardware, and detailed instructions to get you moving!
An AMA-approved sound insert comes installed in the muffler, and an additional 2 meter-max insert in the box.
