That's the same flowmaster I've got on my '99 5.3 and I really like it. I'm curious how you think it compares to your original stock 6.2 muffler - the one 2011 6.2 Silverado I test drove a few weeks ago sounded pretty damn good stock.

Magnaflow 14909, no cats, no resonator, 4" tip dumped over rear axle.

No drone at any speed, quiet cruising, quiet idling, decently loud at WOT.

I won't ever have long tubes so I can't be sure how much louder this set up would be with those.

NKPPhil... I like it alot has a deeper rumble and bout 20-25% louder was gonna remove the resonator to get a little more sound but im waiting on my longtubes to be here in 2weeks so that will give me the extra sound i want. The other reason i went with this muffler is cause its 22" and so is the stock one didnt want to hack up or weld extra crap to my "nice to have' 3.5" piping!
