Graves Motorsports EXUP Eliminator is a direct fitment for the Yamaha R1 (2004-2006) and the all new Yamaha R6 (2017). Simple plug-and-play application allows the removal of the EXUP valve and motor without the "Check Engine light" being activated when using a full racing or slip-on exhaust. Furthers the weight savings after EXUP removal and allows for a cleaner appearance.
