Hey everyone I had some questions about getting an exhaust for my car. I have a 2005 grand prix gtp. I want something that will give my car nice little deep rumble, nothing loud and annoying. I was looking at cat back exhaust kits but for something that I have no idea what it sounds like, that's alot to spend. I saw that zzp has a downpipe I can get for my car and I was wondering if anyone knew if that would change my sound any. I was thinking about getting a 3" downpipe with a cat, but only if it bolts in which I imagine it would. any suggestions or tips would be appreciated
