I decided a year ago to gut my stock wr pipe and in return push up the db reading. After I done that the bike ran much better, sounded good too... "note the sounded" Now its just too damn loud. Cops pop in every now and then if i just warm up the bike with the choke. I run an online store and can get the 03-05 YZ450 slipon very cheap. Is it worthit or should i just look at another stock slipon for my WR? Also im assuming the steel frame bikes have interchangable slip-ons?
