I went wheelin a few days ago, get stuck in the deep mud, but nothing really bottom-scraping. Today I notice that there's a nice dent in my muffler and that my exhaust is hanging down a good 6". Enough so that I can see the top of the muffler underneath the jeep. I took a look, and don't really notice anything peculiar about where it's mounted, but I'm still left wondering what could break to let just the middle sag down. Any ideas on fixing it?
