I'm trying to get an idea of how to build a nice exhaust. Main thing I'm worried about is screwing it up like my st184. They cut the resonator out and put a hot dog in and the car vibrates from the noise it causes rattles. I don't wanna end up with a loud car. So what's the best quiet system that still has a little bit of a note up in the rev range? Should I remove the cats and resonator and just run a muffler? Also should I run 2.5 inch or 3? I do have plans of a 450 hp set up but that's nt for awhile. It's gonna be stainless and my dad who is a welder is helping me. Cheers just trying to get an idea of what to do
