universal muffler

  1. What measurements for universal mufflers will fit on a 2013 EX sedan?

    Basically I was looking into Magnaflow universal mufflers but there are so many different factors line inlet size and shit, and I'm not a gear head, so I don't know how I can determine which muffler will fit on my car properly. I was looking into something like this ... Magnaflow Muffler, 14325...
