i just recently traded in my 05 ram 2500 with the 5.9 for a 08 with the 6.7 i was wondering if there is a way to make it louder without having to run a programmer. I dont want to run a programmer till it is out of warranty b/c i had issues with the dealer and my 05 with a programmer.

 

Louder? Pull the silencer out of the intake, remove the muffler and straight pipe the DPF-back.
