I have an 04 Galant and I'm a huge car guy so obviously I'm going to want to make my car unique. The problem is, is that I'm not sure what kind of exhaust to get. It's hard to find any websites that sells exhuasts that I know will work for my car. I've checked Borla, Injen, HKS, and so on. All say universal, but how exactly will that work for my car? I know I want the exhuast which can produce the nicest sound and would be nice if I could get a horsepower boost from it too. But I have no idea which ones could work for my car. And I want to make sure I can get a good sound, because I have no idea what any of these exhausts' would sound like on my car. So what I'm here for is if anyone could give me some helpful advice or any recommendations on which to get, or if universal's are ok. That would be greatly appreciated, thanks.
