    best muffler for single 2.5 m20 exhaust

    I know I've read a bunch of threads on this but I just want to know a muffler that will sound really nice, no drone just some throat to it.

    If been searching summit racing and I'm having a hard time because I don't know what any of them sound like. I heard dynomax ones sound really nice could any one concern this?

    And if you want to recommend me a muffle just post a link or a part number, thanks a lot guys

    I <3 my Borla. Also have a Vibrant resonator.

    You aren't going to get straight-through, catless setup that doesn't drone, at least a little.

      I planned on running a cat, what borla do you have? Do you have a sound clip of it by chance?

        I love the sound of a Flowmaster muffler on the M20 engine.

        Two chamber (40 series) for a louder option and three chamber (50 series) for a bit quieter.

          not 2.5 but a fairly loud set up.

          Eta downpipes to aftermarket blown 2" cat no res 2" back to a 2"inlet remus muffler.
          Lots of drone but not much rasp

            Almost forgot I had this. Dyno video with some exhaust sounds for you.

            This is IE shorty headers, single 2.5" exhaust with Hushpower center resonator, no cat, and a 40 series Flowmaster.

              Thanks for the vids guys, I was thinking about a flow master while I was searching summit I found this borla muffler, any info on it?

              I really want to get a nice growl out of my m20 because all of my friends (vw kids) are always busting my balls about how a straight six sounds like shit, I don't even know where they heard that? But yea I'll check some of the flow master 40's

                Vibrant may be a good route too...

                    Sounds so awesome. He has bavauto headers, it would probably sound different if the OP doesn't.
