The RS-4 muffler was developed with one purpose in mind... to give you the power to dominate on the race track! 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, two-staged stepped baffle, and an innovative carbon fiber cone end-cap.
Full System includes RS-4 Muffler, Titanium header and tail-pipe, installation hardware, and detailed
instructions to get you moving! Titanium Systems also come with an AMA Pro Racing sound insert installed in the
