I have an 03 cavalier with a silverline muffler....I like it fine but it just rattles the crap out of my car. My doors and dash rattle really bad right around 2500 rpms. I was wondering if there was a way to quite it down, I dont want to put my stock back on, i was thinkin maybe a resonator?? I was also thinkin about buying some 2.25" stainless piping off ebay, and getting an exhaust shop to make me a custom cat-back. I know some of you guys have made custom systems, about how much do you think an exhaust shop would charge me?? Thanks

what is with people and buying stuff off ebay most of the parts that are on there are crap just go to a good stainless exhaust shop and get the pipe there
