Description
Pro Circuit's 304 Factory Sound Silencer delivers impressive performance gains, making it an excellent replacement for your OEM silencer. The longer midsection, compared to the R-304, optimizes exhaust flow for stronger mid to high RPM power delivery. Constructed with a 6061 T-6 brushed aluminum housing, stainless steel tubing, and a FIM-approved 304 stainless steel end cap, this silencer is built to withstand the rigors of off-road riding. The double-walled mounting brackets ensure secure and stable fitment, while the steel Allen-head screws allow for easy rebuilding and repacking. Featuring exclusive E-glass pillow packing, the 304 silencer ensures optimal sound damping and longevity, providing a performance edge and a quality exhaust note.
