  1. I wanted the same thing, the truck sounds great stock but my imagination ran wild with how awesome it would sound if it were uncorked a little. I just deleted the muffler (which was the size of a small bath tub) left the resonator after the axle and I'm pretty happy with it. I could probably go back and re-weld the pipe that the muffler shop put in to seal up any small leaks that may be present. But over all I can set off near by car alarms with cold starts in the morning haha
  2. I've got a 2013 Sierra Denali, pretty much all stock, muffler delete, and a CAI but no tune yet... I'll have to post the pic later when I get back to the shop, but I ran a 15.5 at Tulsa Raceway Park. I'm hoping with a tune I'll drop into the high 14's but we'll see. Does anybody on here have a preference on a tuner? I'm leaning more towards a custom tune from XP Racing in OKC, but they don't have an AWD Dyno...
