What problems did you run into with the Barkers boost? I have the Barkers on my sled and XX. I give that exhaust an absolute beating and I haven't had a single problem. I think its a great exhaust and puts down some awesome power!The Barkers uses a exhaust header gasket, unlike the Sparks. The flange is half as thick Sparks, that uses the longer 450r exhaust bolts. I like both exhaust, but the Sparks is built alot stronger/ better:tup:
I won't even get into the repacking of the Barkers muffler lol.
