I just installed a Plog on a friend's 04 Imp SS which already had the DP. Sounded... the same. Kinda hard to tell any difference when he already had the resonator removed and runs dual Magnaflow mufflers.

When I put a 2.5" DP on my L36, I noticed it brought out more details of the exhaust note, but it wasn't louder. Just sounded like a speaker that had better frequency response.
