Hello, new Member here, not new to crx's (just bought my fifth) anyway, I am wondering which muffler is the most efficient to get when you are upgrading to 4-2-1's. The car I just bought dosn't have a muffler which is fine, but if I am going to buy one I want to make the right choice. does anyone have any experience in this area or know where I would look for an answer to this?? Thank you
