m50 rattling when coming to a stop

[e30_kid89]

I have a similar sound. At around 3k when decelerating I get a wierd exhaust backpressure noise. Almost like a loose exhaust rattle.

I'm thinking it's the dimensions of the custom exhaust or when the pipes were being welded together it made an irregular texture on the inside which at the right flow and pressure the exhaust resonates in a wierd way.

add me to the list. my m50's been doing that too...almost sounding like its farting lol.

re:

Click on the link it will tell you the most common ratteling cause from m-5o (only for people who can read!)By the way if you want to change both tentioners, go i head no sweat off my back...By the way i would replace the one the easiest to change first,just seems easier to me... I don't know i know it fixed my noise..
