I run the full tti 3" exhaust with their headers on my challenger. It's quite loud when I'm on it, but when I'm trying to be respectful it isn't bad at all. Mine runs all the way out the back to tips.

I think getting rid of the dump before the axle and installing tailpipes will probably make a big enough difference to keep you out of trouble. twocents
