Im guessing im the Explorer in question lol I get several compliments on my muffler, even a few of the mechanics at the ford dealership were impressed with it. My opinion... not to loud, not to quiet... just right. Of course i do have duals, so that could very well change the sound, and it be louder than a single out. I personally don't like the sound of flowmaster, to loud and it gets annoying (i speak from expierence, i had it on my last truck, and it got old fast). But exhaust/mufflers are a to each there own thing.
