Exhaust odor/smell in clothes?

[upshiftoverdrive]

As I recall, (I installed them ONCE), they fit VERY snugly, certainly Not loose.

Should you decide to screw with it anymore, a muffler shop has "exhaust pipe expanders".

Bring the pipes in question(loose) down there with the mufflers and have them expand (and make round again) until they fit snug.

That should help a bunch.

New clamps and tightening them can ONLY tighten the outside pipe so much.

If the inside pipe is TOO SMALL, you will have a leak no matter what.

Good idea. I was thinking about marking with a marker how far the cans slip on to the y-pipe. That way they can extend the pipe out, only as far in as it needs to be.

I am pretty happy with the fitment though as it stands.

Thanks again. Hopefully OP was able to find his leak too.
