Check out spintech they are pretty cool I had one on a 2000 classic body 3/4 ton with 5.7l. I have a big magnaflow dual 3in and single 3.5 out on an 05 6.0l It sounds killer and doesnt drone at any speed or rpm. A buddy has aero and it sounds good. Tail pipe has lots to do with sound, I changed the length and exit a few times to get what I wanted.
