I went with the JBA titanium ceramic coated shorty's, a custom mandrel bent y-pipe, and then a Magnaflow cat-back with new 5" black powder coated dual tips installed on my 19'.
For me personally, I don't prefer super loud and raspy, screaming exhaust systems. I've had Corsa, Borla, FlowMaster, and the one I keep going back to is Magnaflow because to me, it sounds best with the HEMI's. It has a nice deep growl at WOT, near zero drone at highway speeds (I always drive with MDS off), and gives a nice little bump in go-go.
The Magnoflow cat-back system, now combined with the JBA shorty's and the custom y-pipe have even better sound, and the flow is super with some increased fuel economy too (until I smash the pedal to the floor...lol)
Everyone has their own preferred sound from their exhaust and how they go about getting there. Enjoy the experience and the benefits
