    Yet another exhaust question...

    I have 91 318i m42...I just installed Dynomax Super Turbo muffler. It sounds great, nice deep rumble sound, NO tin can effect.
    The only problem is - you guessed it - it is a little loud...at times.

    -Idle sound is great, a little louder over stock.
    -Low throttle acceleration is nice, a little louder than stock
    -Mid to full throttle - a little annoyingly loud from 2k-4k RPM.
    -Above 4k RPM - the note is nice and not too loud.
    -Cruise is nice deep sound, a little loud for my tase

    What I want to get:

    -Quiter sound overall, idealy I want to keep the sound tone, but with a quiter note below 4k rpm and louder above 4k. I may get soundclip later (it is up, see the 3rd post with the linky to utube.

    What is needed for this? Should I iget bigger resonator?

    BTW: Header, cat and small glass pack looking thingy were on the the car from when I go it, mufflet had 2 butned holes in it, sounded very stock and quiet.

    Yeah either add a resonator or replace current one with bigger.

        Here is the link to the clip. I actually like it how it sounds from the outside, about 5 ft from the tail end.... Sorry for the blank picture. hehe, my phone screen shutdown while recording....sound is the key anyways! lol

        Dynomax super turbo muffler sound with bmw m42 engine. No external work done to the engine or exhaust except the muffler.

          I'm running a super turbo and a 12" Vibrant Resonator. It's still overly loud/droney at cruise RPM.

            My E30 is M20 powered but the guy that did my exhaust for me ran a glass pack up front and magnaflow muffler. Sounds great.
