    HELP!!! In cabin drone

    Guest-only advertisement. Register or Log In now!
    I just installed a magnaflow non resonated exhaust on my s3 with a bullx downpipe. I had an A3 with an Apr downpipe and dinan cat back. My issue is the horrible drone on the highway. It's not as loud my a3 outside, but too loud inside. Resonators will help but I was wondering what resonators you guys run?

    I had the same issue and installed a resonator and it cut the tone by 2/3 except mine was just loud as F! Not really droning. install one of these or just a regular glass pack..the longer it is the more it reduces the sound or drone.

    You can try insulating the trunk and underneath the rear glass. There is no insulation at all stock under the rear glass. Did it on my s3 also and itís made a significant difference.
