My buddy has a 2001 GT and a stock hpipe that someone gave him. He was wanting to gut the cats on the stock pipe and use it on his car. I thought maybe we could cut the back 2 off and replace them with the same size diameter pipe and just gut the front 2. Or maybe just gutting the front 2 and leaving the back 2 on. Would this work and give about the same performance as an o/r hpipe? We have a little time on our hands and just like messing around trying different things. Plus he doesn't have alot of money to spend on his mods so he's trying to do it as cheap as possible by doing things himself. I also thought about measuring the box on my prochamber and maybe making one up and welding it in place of the pipe on the hpipe.
Just looking for some opinions. Thanks.
