Mufflers

Trying to figure out why the muffler on the Honda CRV sounds like it has a box of rocks in it, a noise that only began this week. After Googling the problem, and discovering that mufflers have nothing like rocks inside, duh, I started the engine, which got the sound to resume, then got out and, just for the heck of it, nudged the muffler with my shoe. Not a kick, just a nudge. The sound has stopped. Weird. It’s off to a muffler place first chance I get.
