Jake, I'm pretty sure that, not only does he not running a muffler, it doesn't even have the catalytic converter. I put a straight pipe exhaust on my dad's '04 LLY Duramax, which eliminated the cat and muffler, and it sounds EXACTLY like this truck.

Do you have the muffler on? Cause it would sound awsome off.
