Exhaust rattle: transmission to exhaust bracket smashed

JayReplay · 01-15-2010, 03:27 PM

I recently heard a rattle toward the middle/front of the car whenever I put my car into park or whenever I slowly accelerate from a complete stop. I took the car the dealer for a check up. My SA told me the transmission to exhaust bracket was smashed. He believes I hit something seeing that my car is lowered (possibly went too fast on a speedbump). The charge is $225. Is anyone familiar with this bracket? I would like to possibly buy this exhaust bracket and have a local muffler shop install it. Thoughts?

If it's just a bracket I'd recommend getting the part from Tischer and installing it yourself. You'll probably save more than 1/2 what your SA quoted you.

i had something like this happen to me in my 328i. i stripped the screw that held the exhaust bracket, so it was impossible to tighten. at certain rpm's it would rattle horribly making my car sound like a and old beater.

it was around $300 to fix at the dealership, sounds about right.

Do you know where this is located? I looked under the car and only noticed a holder that was around the two pipes. It was a bit mangled and the exhaust shop simply put a spot weld on it to reduce the movement. This was under the rear passenger side seat though. I couldn't find anything by the transmission.

Here is the exhaust diagram I pulled up from REALOEM. While inspecting the car, it appeared that part 13 was bent. My exhaust shop spot welded this piece to the pipes, but I still hear a slight rattle. It looks like either part 10 or 12 needs to be replaced. Does anyone know if this is a straight bolt on I can just remove/replace?

I don't know if this is helpful but...

Mr. 5 just took his off and left it off to fix an exhaust rattle.

thanks for the info. My part 13 is bent like yours and it rattles alot during low rpms like idling at a light, or driving in a parking garage lol. makes your car sound like its breaking down! also, some vibration when revs are up. Again much appreciated Jayreplay!

I was working on my car recently and took part 10 and 13 off and didnt put it back on when I went for a test drive, I dont get any rattle during most my drive. I plan on putting it back though just for extra exhaust support. I think it rattled once when I went over some rough road due to no support.
