Yesterday I mounted up my new Tyga exhaust. Once I got the stock exhaust (2 1/2 hr. battle) off it was pretty easy to install this exhaust. I think KTM built the bike around the stock exhaust! Anyway, new exhaust looks awesome and sounds good. I started it just for a minute or two as don't have PCV or air box mod installed yet, both on the way to me. Can't wait to get all done and ride it.
