hey guys so I have a meisterschaft Super Gt on my 2013 335i and am starting to get annoyed with the rattles and vibrations inside the car. I have the chassis plate under the car removed after install because it was unbearable. that definitely helped, however the vibrations are still there. I wanted to know if anyone has some tips as to what else I could do to help reduce the vibrations. I can handle the drone cause I listen to music loud. I've read that dynamat in the door pa els helped and I will do that when I get around to upgrading the speakers in the car. however aside from that any other suggestions?

It's much better in sport mode however in comfort and eco it's really bad cause the romantic is usually below 2000

Have you contacted GThaus for support on this issue?

I'm dealing with vibrations as well after my DP install, I'm assuming something may not be lined up 100%, I plan on getting it back on a lift and try to make slight adjustments and hopefully solve the issue

Let us know how it goes

Look up "Mechanical Resonance"

I will contact GTHaus since you've suggested. I just didn't think they would be able to do much, but I guess they could tell me where to start in finding a solution to the problem. I looked up mechanical resonance and it makes sense, I just don't see a great number of people with aftermarket exhausts complaining about it. At first I though it was just the fact that the quality of the parts inside the car were bad but knowing other's don't have the issue makes me know it's an isolated issue and there must be something I can do to tone it down if not completely get rid of the vibrations. I will also have someone take a look under the car while we have it on a lift to see if we can find a specific area on the pipes from the cat to the tailpipe that would need a new band clamp or something.

Thanks for input guys.
