    Friend of mine got rid of his GMMG because of the rasp with longtubes.

    Went with Magnaflow.

    GMMG sound pretty good! They still get a little raspy at times though...

    I have the same exhaust setup as you for now lol, this setup is raspy but especially around 2500-3500. I feel sorry for anyone with a A4 with the same setup, not being able to skip the terrible rasp RPMs.

    I have a 396ci with FAST92/92 Kooks 1 7/8 LTs Hooker ORY and GMMG catback. if you want more details let me know

    It is deeper than most catbacks. and I think it looks great.

    I've had Hooker CB, Magnaflow CB, TD's with 1 chambers, 2 Chambers and bullets, and Borla CB. The GMMG has the most unique sound and tone. TD did help me with topend power but I lost some low end and didnt gain any torque with them. so I thought 10rwhp isnt worth the ground clearence issues, and drone inside the car.

    now on the driving one there is some I guess you would call rasp believe it or not the Kooks y-pipe didnt fit right and the I-pipe of the CB came off and I didnt know it till later that day because it started banging the bottom of the car. so I got my Hooker y pipe on there (it fit better than the kooks) and it sounds perfect.

    so here you go

    i love my gmmg! i have never had anyone tell me they didnt like it either. but yeah it is pretty deep and sometimes it gets a little raspy when its not warmed up, but after that i get nothing but sweet music. it sounds different from a lot of the other catbacks out there, and way better than the loudmouth in my opinion, which is horribly raspy. but people love that....?
