Rattling exhaust tailpipe

[al123]

I saw a number of posts about exhaust pipe rattling. i now got it. Anybody has a assembly diagram so that i can figure out what is broken/loose there? tks

Either the clamp is loose or the weld on the tip is likely broken.

another alternative - the shape of the internal pipe to the tailpipe doesn't exactly match - mine were not perfect & would rattle, despite the clamp being tight. I slighty re-shaped the inner to be a snug fit with the tail pipe - no more rattle.

Dont have a diagram for you, but it may be easy to figure out.

I had two previous sources for a rattle in the past, easily diagnosed and fixed. If you crawl under and look just beyond the tips, there is a clamp that holds the two pipes together and secures them. The weld on the right clamp broke on mine. Replaced under warranty. The second source of rattle at another time was the cat converter. Tech simply hit the offending cat with a rubber mallet, reproducing the rattle. Again, replaced under warranty.

Sometimes if the exhaust tip bottoms out, it deforms inside where the sleeve goes over the pipe (inside the tip)

If you cut the back of the tip, to slide it off the bolt and remove it, and then add another washer on the inside of the bolt, you might be able to tighten things up so the "ringing" or rattling stops. You could also put a screw there through the pipe.

Tapping with a mallet is a good way to find out where the noise is coming from.

There is a TSB about exhaust rattles (for contributing members)
