Product Description

EXHAUST EVO TI/CF RSV4 21

• The combination of race-proven, lightweight materials, exceptional production quality, perfect design, amazing sound, and top performance makes this exhaust a must-have for discerning riders that demand the best
• It is constructed with a carbon-fiber muffler outer sleeve and end cap, with a fully titanium link pipe and inner muffler structure, matched to high-grade titanium alloy for the headers and collectors, resulting in a full system that is 44% lighter than stock
