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
 
what do you mean by efficiency? Are you wanting the best flow or are you wanting something that is quiet? A muffler that tends to flow well and is quiet would be a twin loop.
