    Just how bad is my exhaust drone?

    This is on a 540i, with the rear muffler removed but the center "lung" resonator still in place.




    I'm thinking i really need to pick up a mangaflow muffler...

    ALSO looking for 540i 6speed manual transmission sets (2001+ pedals with switches, driveshaft, gearbox), for the 6speed swap! Probably not for a while....

    You need to tighten up the suspension, or whatever else that racket was.

    You shouldn't have a drone with your scubas removed. I'm guessing you might experience some drone if you gut the interior from the car though.

    There is some. As I've said time and again... guys say "no drone" at first, but once you live with it, you notice it and it can be irritating, depending on your driving environment/conditions/etc. As I've also said many times, its not an all the time drone, its a low/mid-load low-mid-RPM blaaaattt/drone... once you WOT it, or, get some RPMs, it goes right away.

    Joe if you stick any kind of nominal Magnaflow or clone on there, you'll be fine and pleased I think.

    already purchased, actually, to be installed next week. magnaflow 14816
    not sure i'm married to the y resonator though, the vibrant performance res apparently is an excellent no-drone good-sound replacement
