Sound bites?

Right now my truck sounds great I think. It's a 6.7 fully deleted with 5" TBE, and no muffler. But I'm thinking for deer season coming up I might want to put a muffler on. So I was wondering if anyone with a similar setup had video/sound of their truck with a muffler. Also, will there be a mileage decrease, and where would the best place be to put it along the exhaust?

Thanks!
