On DPF back kits, they really do nothing for sound or performance. The sound is smothered by the CAT and DPF. Really, the only benefit you'd see from it is reduced tailpipe temps during a regeneration.

I placed one on my 09' mega and noticed a good tune when all the windows are down, not much on the inside though. Overall i looks bad-ass from the rear, besides after 100k im planning to rip all tha dpf crap out!
