wondering if they were any good and if they had that good low deep rumbling sound or if they were the ricer sounding exhausts and if they were easy to install myself  

Ginson, ha, they're full of it, have you ever read their ads? They say they have a 30% increase in power. Really Mr Gibson? 30%? That means my Tahoe will pick up over 60HP with your exhaust? ####.

There is one name for exhausts, Flowmaster.
