No a dpf back exhaust is a complete waste of money

yea, im just looking for something to hear the turbo a bit more, no mileage or performance gains... Is there any good suggestions? What about getting rid of the ugly stock tips and putting a nicer tip on?

nope, i have a MBRP five inch dpf back exhaust with a RBP six inch black tip. It looks really nice but doesnt make any more sound. Its just a matter of preference if you like the look of the stock tips or you want a large exhaust tip.

You have to delete to get more sound.

DPF back straight pipe will get rid of the factory resonator but you really wont notice any sound difference like mentioned above. The dpf is a great muffler LOL, but a 5" dpf back does look pretty sweet, it just wont do much for the money. Maybe try an intake with a dry filter(I have AFE stage 2 pro dry s) on my 6.4 and the dry filters are supposed to be "louder" meaning more turbo noise makes it through. that may get you a little bit, i know my intake sounds pretty sweet and is easily put back to stock if needed. FWIW, I left my intake on for warranty and returned everything else to stock and they said nothing about the intake.

The dpf is about 4 feet with of filters, baffles and sound deadening materials. Without a delete I think you're sol.

the OEM tips are also designed to handle the heat of regens. I would mess with it without a full delete.

the dpf back kits are also finned in some way like the factory to bring in cool air and mix with exhaust to lower the temp of the exhaust exiting. Some designs are better than others but I ran my magnaflow 5" dpf back for 17k miles with no issues on my 6.4.
