Key Features
- 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
- Developed for use on closed-course competition circuits, this racing track–oriented system requires mandatory remapping and removal of the passenger footrest
- It delivers increases of power and torque of 4.0 kW (5.4 hp) at 13,000 rpm and 3.8 Nm at 7,700 rpm when measured in back-to-back comparisons against an Aprilia RSV4 with a standard stock system on the in-house dyno
