I'm on the market for some mufflers for my K10. I HATE glasspack raspy sound, and I think these new trucks w/ bolt on exhausts sound like crap. They all sound throaty but in an ugly raspy way, like a 1991 chevy lumina with the exhaust fallen off. I want something loud, but I want a true, performance, deep rumble! No snap crackle and pop, just something that sounds absolutely awesome.
