The Graves Motorsports Works Full Exhaust System for the Yamaha R6 is the exhaust system to have! This high performance exhaust features titanium head pipes and billet aluminum flanges. An O2 sensor bung is provided for use with the Yamaha O2 Sensor. The R6 Works Full Exhaust System includes an added cross-over head pipe feature, along with a more aggressive head pipe taper. These features allow for an increased throttle response and low to mid-range power delivery without affecting the peak power output.
