Description
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.
Slip-On includes RS-4 Muffler, stainless steel tail-pipe, installation hardware, and detailed
instructions to get you moving! AMA Pro Racing sound insert comes installed in the
muffler.
