Have a 2005 V6 convert with 5 sp MT. Have had a rattle underneath for years but never found it. Thought it was my exhaust brackets but not sure. Mostly at low RPMs and when I punch it. New to this forum so hopefully some of you smart folks can help!
I myself had duals put on it and when I make a hard right the pipe swings over a hair in the rear and rattles against the suspension. Sounds like crap but I did isolate it to the driver side exhaust. When I walk around my car in the mornings I usually kinda kick that side to the right a tad. One of these days I will get the pipe in the right spot and weld that punk down...

Oh yes. There is the front most hanger bracket behind the cats. The 6 has the GT exhaust hanger up there (at least on my 07 pony package) that started loosening up and required a BFH adjustment directly from the bottom side of it.
Big effing hammer. The bracket just needed to be popped on the bottom a couple of times to spread the sides out into place again. Kinda hard to describe. When you get under it you'll see it. Pop the pipe with your hand about halfway and you'll make it rattle. Hopefully that will help. Also make sure that the whole thing can't shift to car to one side or the other and rattle off anything.
