I am looking for something that will allow my engine to flow better but I don't want anything loud as hell that will rattle my car apart or be annoying on the highway. Does anyone know of a specific muffler that would be a good fit for what I want? I saw some flowmasters on ebay for like 80-100 bucks but I think they are a loud model. I just need some input and advice. I am stock right now besides intake on a b16a2 del sol.
