I'm pretty sure this fell off my 2008 Honda Fit Sport, unless I somehow managed to pick it up off the road for it to grind under my car for 20~ ft before falling off. As you can see, it got flattened by traffic before I got to it. I think it's a heat shield for the exhaust somewhere, but exactly where did it go? I don't really want something important to melt because it's missing now lol
