Hi, this is going to sound lame but I'm completely new to cars...I recently purchase a Fiat Punto 1.2 16valve ELX. I really want to put a cherrybomb back box on it but have no idea how I can do it, I looked at the exhaust diagram and it doesn't look like I can simply slide the old back box off and replace it with a cherrybomb due to the bent pipe on the rear of the old back box..I'm puzzled as to how I can get around this! Any help would be appreciated, cheers!
