I've had an 8.1 before. It was an '02 2500HD. I had Magnaflow on it and custom tune on it with HPTuners.
However, despite my insatiable urge to modify everything I own, and of course letting a Big Block breathe, one of the things I actually enjoy about driving either Suburban is the peace and solitude compared to the GTO, G8 or Cadillac. All of which have lots of exhaust work in one way or another.
