If you really want to let your 2009-2011 Yamaha R1 bark, the Voodoo Moto slip-on will definitely give you the sound you’re after. The shorty pipe is CNC mandrel bent for a perfect fit and finish, then master welded to host a custom designed, removable and rebuildable Voodoo baffle. It’s finished with a laser-etched Voodoo logo.
The muffler utilizes the stock headers, making installation quick and easy. Just remove both stock undertail mufflers and the heavy crossover pipe. The Voodoo retains the stock O2 sensor for trouble free performance (though some type of fuel management is suggested for optimal performance).
When ordering online you must select a surface finish, and you can also add the Voodoo Speakeasy Variable Exhaust Insert to lower sound output up to eight decibels to keep the neighbors off your back.
