i got a dyno max cat back. took it to the shop so they could put it on... the got all the old off.. and this pipe is 3 inches off the cat. and the cat is made for 2 1/4 inch pipe. so they said they couldnt bolt it up. it would sound like crap (worst exhaust leak ever) so now im stuck with this... either a new cat for over 80 bucks or somehow rig it on there.... i just have to tell them what i want done. in the mean time i running around town with the exhaust coming right off the cat. it sounds like one of those big jacked up trucks. so what do you guys think i should do with out spending another 80 bucks for a new cat.
