    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

          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.
