I had the exhaust TSB (move pipe to rear of wheel instead of in front) done last week. They replaced the muffler and ran the pipe to exhaust behind the right rear wheel. Now there is a pretty good drip of water that comes out of the rear of the muffler,(not the pipe, but the rear housing of the muffler) It is just clear water, I assume from condensation but why is it suddenly there and why would it not come out of the tail pipe instead of the muffler?

Kenster,
I was about to post the same question.
I have water leaking from a very small hole behind the muffler in the muffler housing.
The hole looks like it is supposed to be there.
Guess this is normal. On warm up on cold days I end up with 2 water spots:
One under muffler and one at tailpipe.

I'm not sure but could this have anything to do with an exhaust pipe bend (Upwards) past the muffler? That would certainly trap water in the low spots.

Relax guys it is suppose to be there, so the muffler doesnt rust out from condensation. The muffler is lower than the pipe thats why it doesnt leak out of the pipe all the time....If we sit idle in our patrol cars along time and take off I have notced about a cup of water pour out the back but this is normal.......Good luck, Dave

 

thanks for the response. Makes sense to me!
