Decent exhaust in all categories but in my opinion has a major design flaw when put on a CRF250X.
When trying to lift the bike onto the stand or move the bike around in the back of the truck, there just isn't enough room between the fender and the exhaust to use the traditional grab spot under the rear fender without burning your hand from the much too close exhaust.
It could also be a major problem if you're a woods rider, like me, and ever have to try to lift the rear end out of a mud hole after getting stuck.
I've never encountered this problem on any other bike / exhaust combo I've ever had. The stock Honda muffler doesn't have this problem.
Needless to say, I'm pretty disappointed in my purchase and wish I could return in.
