How does it sound? I assume you're replacing the muffler only and leaving the rest of the system (flapper and resonator) in place? These trucks are way too quiet, I'd like mine to be as loud as my dad's bone stock '11 6.2l.

The sound that it makes on a cold start or at WOT approaching 4k rpm is just sweet!

No I replaced from the muffler back so no flapper or resonator,sounds amazing I have a Diablo i2 and running Diablo tune with no DOD (v-4) love the sound

Right on. I might try it but leave everything else in place as I won't be tuning or disabling the DOD. My only other mod would be an airaid MIT if I have my buddy in Washington ship it to me.
