Graves Motorsports Titanium Slip-On Exhaust System features the same quality as our full exhaust systems but allows you to use the stock headers and EXUP Valve. Unlike most of our competion our slip-ons include a Y-pipe to eliminate the catalytic converter thus maximizing weight reduction and producing big power gains of up to 7.6 hp with the use of a Power Commander. This exhaust system features; titanium y-pipe & s-bends as well as titanium silencers (w/ snout style endcaps).
