quiet exhaust
I agree with Adam. The regular super turbos have a main case that is about 14" long. The Hemi super turbos have a main case that is 18" long. Don't be confused by the overall length that includes the 2-3" inlet/outlet on each end.
Flowmaster also has a 70 series that should take the bark out. I run 50 series delta flows with an x-pipe and it is not load enough to make people look up when I go by but certainly is loud at WOT.
