I have noticed that on occasion, I have water dripping from the right side (passenger side) of the muffler at the bottom where the side plate is welded to the body of the muffler. This water is coming from the inside of the muffler and a rust spot has formed where the wate is dripping from.

Has anyone else noticed this? And what is causing this?

Thanks for your input!

Most likely normal condensation from moisture that gets in the pipes. All cars do this. Unless you have a stainless steel exhaust its gonna rust over time. What we have is just aluminized steel I believe, the standard for stock automobiles.

My Saturn SL2 in 1994 came with a stainless steel exhaust standard and in the 10 years i owned that car in Wisconsin, I never repaired/ replaced the exhaust.

The actual tailpipe will rust, but the chrome finisher around it will stay shiney for a while.

I read somewhere, I forget which forum, but a guy put a 350Z exhaust on his Murano. It took a little customizing, but he got it to work. If thats the true case, then you could do it in SS as well.

Additionally, the emission system itself produces water vapor at all times. That also turns into water droplets on the way out.

If water (condensation) is dripping from the muffler it means you already have a hole in the muffler...perhaps a bad weld at the side plate....keep an eye on it to see if it gets any bigger....if water comes out, exhaust fumes can escape as well....

Report it to the dealer, It may be treated as part of the emissions control system and be repaired under warranty.
