I own a 2001 SE 4X4. As for the sound, I think it just perfect, not too loud, nice and deep. If anything, when stomping on the gas, the sound coming from my drop-in K&N air filter is louder than the exhaust! At idle, it's as quiet as the stock system. If it weren't for the extra "kick in the pants" I now get, I can't really tell much difference in sound between the Gibson or stock. I'll try to get some pic's tonight.
