2004-2006 Yamaha YZFR1 Slip-On Exhaust System by Graves Motorsports
Graves Motorsports
2004-2006 Yamaha R1 Slip-On Exhaust System features the same quality
as their full exhaust systems but allows you to use the stock headers and EXUP Valve.
Unlike most of the competition, Graves Motorsports slip-on exhaust systems
for the 2004-2006 Yamaha R1 include a Y-pipe to eliminate the catalytic
converter thus maximizing weight reduction and reducing heat build-up. These
exhaust systems features a stainless steel Y-pipe and either carbon fiber or
titanium silencers with conical end caps. Gains of 8 hp can be achieved with
the the use of a Dynojet Power Commander. Installation of this system will
shed 2.7 lbs from the motorcycle.
