I just recently got new exhaust on my 6 i got dual flow master 40 series with a custom x pipe and turn downs ,
it sounds really good at low RPMs but after about 2.5 rpms it just sounds stock will it brake in and get louder or will it stay low

The tone will change a little as the mufflers break in, but generally what you hear is what you get.

These are even firing engines, which up top makes the exhaust smooth out enough as it is ... X pipe makes it even worse. all 4 stock cats keep it very quiet as well.

Flow 40s sound good, dont get me wrong, but Id say there are other options you should really look into.

Thats the same setup I first ran ... wasted money IMO.

sorry but the 3.8s werent made to be loud, I had a high flow cated H pipe on mine and it sounded real nice but wasnt that loud

This makes no sense at all. Any car can be loud with the right exhaust on it. My V6 is loud as hell with a dual CAT-back exhaust plus X pipe.

When I first got my exhaust done, they removed 2 of the 4 cats and ran pipe straight back from that, I got about 6 miles down the road and turned around and went back to have some resonators added cause it was WAY to loud. Current setup is removed the second set of cats, h-pipe, and two high flow resonators, it's loud enough to get noticed but if I don't drive with my foot on the floor I can pass a cop without so much as getting a second glance from them.
