Interesting "new" device FOR 04-NEWER GMC'S
I came across this following an online article in Trailer Life. Looks like an alternative to chopping up the factory exhaust system. Since there is no modification to the original vehicle, it probably doesn't upset the warranty apple cart, either. Once you get to the Banks website, look up SpeedBrake on the right side of the screen.
