        M50, ebay SS rep headers> single 2.5in mandrel pipe> spun cat> flowmaster dbx> magnaflow 12638. The mid muffler hangs real low, didnt plan that one out too well, I'll need to get a slimmer muffler eventually.

          I know how hard it is to piece together the exhaust you want for your 24 Valve swap, i did Many hours of researching before I went ahead with this. General Opinions are,

          -Sounds Glorious in person
          -No Rasp
          -Alot of Drone except at 3000 RPM, which is 73 MPH (2.93, ZF Trans), which is where I cruise on my way to work, so it works out.
          -LOUD, Two mufflers doesnt mean its gonna be quiet. Mostly because their strait-Through Designs would be my guess. Ive only been pulled over once for it. But its loud. But its awesome as well.

          Dont plan on changing it anytime soon, I hung the center muffler too low so it scrapes everywhere. Dont do that. Might add something else like a cat to queit it down. maybe a bigger center muffler.


          Setup is

          Ebay long tube headers
          Connected to Flowmaster Y Pipe
          2.5 inch tubing
          Borla PROXS Mid muffler
          Vibrant streetpower Stealth at the rear

                  Updated my exhaust with a new high flow cat. Its not as loud on idle but the sound is much cleaner.

                    just posted that thread yesterday

                      Was going to use stock piping, then the guy just ran all new pipe without calling, but in same size 1-3/4"?!?!?! Why?!
                      Anyway, Borla Pro XS dual 2.5 in/out 400286 is the muffler, no cat, no resonators, just straight back... Too loud for my liking, so tomorrow when it comes back from the shop I'll post what it's like with the resonators.

                          What muffler are you running and what is your setup? I was thinking of doing a 3" single back into a single in dual out muffler. I like Magnaflow but I don't like rasp and that had no rasp. I also liked the very first post of the tri flow exhaust and I am assuming that's Billy Boat and I am not spending that much on a daily driver lol, aluminized is plenty, I will do a stainless muffler though.

                                I'm bumping this thread since it's slow and needs more posts. Now I know there's a lot of good sounding E30's out there. Post some videos whether it be an M10 or S85. I just got mine up and running again so I'll get some clips posted soon. ;D
