Only a little concerned. Today I drove my JK to work, about 30 miles each way. I figured if there was water in the muffler it would have been driven out during that ride. About 3 hrs later I drove to friends house and noticed a wet spot under my Jeep a noticed water leaking from the actual muffler. I thought strange but it was just water. I should mention I live in Az just outside of Phx. And it’s pretty dry place so you would think a 60 mile drive and the desert dry this would not be possible? Any ideas?
