Help with Turbo
 

I got an 07 3500 6.7, i am trying to figure out what can i do to the turbo so i can hear it alot louder.:hmmm:

Ditch the factory exhaust, get a turbo back kit, no muffler or cat.

Then you'll need a tuner/programmer to turn off the codes set by modding the exhaust.

That and an intake as well. The intake with an open element will make it quite loud.

Intake will make a differance. Getting a DOC/DPF delete kit will make a big differance, but then again you will be riding dirty and way out of emissions compliance.
