Just installed GMPP Exhaust
I got a good deal on GMPP "Performance" Exhaust.
Install went quick it literally took 15 minutes.
Hows it sound? Not as loud as I'd like - actually it's really quiet. You can't hear it at cruise with the windows up and there is zero drone.
I've got a video I'll upload to you tube

My daughter (she's 2.5yrs) just said "Daddy loud truck" and she pointed at the screen. She seemed to like it and I think it sounds pretty damn good as well. Very nice!

That's GM Performance Parts?? How much did that exhaust cost? Sounds Good!!! That's what I'd love to have...something that flows, but without the loud sound.

The tone isn't bad, just way too quiet. It should be like 40 series flowmaster loud IMO. I saw one installed on an 08 Sierra and it looked just like a Magnaflow would on stock piping. Not worth 600 IMO when you could do the same thing yourself for a hundred or less.
