Thank you guys for the replys.
Yeah I have a high flow cat on my car right now. Car never passes etest anyway with the HFC so I was going to run a test pipe and whenever I need the test I swap in a stock cat...
I currently have a 4-1 DC headers and two resonators and a Greddy Evo2 muffler. So and my car has zero rasp, super deep note, I don't think my car is going to sound raspy if I get rid of the cat, correct me if I'm wrong.
I didn't know I needed back pressure that's good to know... one of the other reasons I wanted to swap a test pipe in was because, don't judge me for this, but I've herd it makes your exhaust pop and shoot flames which I'm not going to lie is kinda kick ass and I lover it
My car already pops quietly when I let off the gas so this might let the roar out some more.... but I don't know
