    Question Big Turbo exhaust advice? Looking for minimum drone with GTX2554 (MRX)

    Guest-only advertisement. Register or Log In now!
    Hey guys, I just installed the Mountune MRX turbo kit, and its great so far (working through the tune revision process). My car has a stock downpipe and a Tsudo 2.75" exhaust. The Tsudo, with stock turbo, is...droney. Pretty gnarly drone from 3k rpm to about 4500 rpm, where it entirely disappears. I installed some sound dampening in the trunk/spare tire area, but it didn't help much.

    I was hoping that maybe the change in turbo might take the savage drone beast, but the opposite occurs. The car is even dronier with the MRX . I daily this car, drive my 5-year old son in it and drive it on the freeway a lot. Drone in that rev range isnt something I can live with. I have some sensitive ears apparently, which makes sense...I wasnt kind to my ears as a kid, going to lots of concerts and race events without ear protection. At age 37 I just cant handle drone. My kid doesn't like it either :)

    Any suggestions on what to do, as far as an exhaust? I don't want to go any smaller than 2.5". I considered swapping mufflers or having a helmholtz resonator or "drone pipe" installed by a shop, but locally I cant seem to find anyone confident that they can figure out the math and cancel the drone properly. Also swapping mufflers is a pain because of the unusual 2.75" exhaust size.

    Maybe the Mountune turboback to match with the MRX? I have their turbo back on the stock turbo and it's pretty good about being growly under acceleration and pretty quiet otherwise.

    I would recommend the mountune exhaust. It's really tame and has no drone. X37 and catless downpipe here.

    Cobb is another good 2.5" exhaust option. Basically, whichever you can get cheaper since they are very similar.

    OT: Shouldn't you have an aftermarket downpipe?

    What you need

    Upgraded intercooler such as mountune PN 2364 IC BA1
    Cobb Accessport - Mountune supplies a base tune for your Accessport
    mountune Intake or suitable option PN 2364-CAIS-AA
    Upgraded High Flow Down Pipe
    Replacement Blow Off Valve such as our PN 2364-BOV-KIT
    You could try extending the tips a bit further out from the bumper - that helps with the in cabin noise

    I have a resonated mishimoto catback with cat less dp. It's really quiet till over about 20psi. This is on a gtx2860. No drone.

    Really? Stock is big enough to flow?

    Kinda surprised it's droning with the stock cat still in. There should be a lot of catback-only options work little to no drone.
