Moto gp style muffler.Titanium steel 51mm Comes with only 1 aluminum decal that is designed to go on muffler. Choose one color and send me a message, decal will not be applied on the muffler, you will do that on your own :D .look in my store for more exhaust variations! No returns! make sure it fits your bike, as all bikes are different you might need to modify.
