My LWB K1500 has the dual kit and it appears to fit quite well. The tubing is amazingly thick, I doubt it will ever rust out....the turbo muffs and hangers are another story. I can't comment on how it was to install since the PO added it to the truck. As far as fit goes, the muffs are tucked up between the frame rails and the drive shaft and all the tubing stays up nice and high until it pokes out with the side exit behind the rear wheels. I assume the turbo muffs on it are the ones that came with the kit. They sound nice, no drone, but the lack of a balance pipe(tough to have on a 4x4) makes them a little bit "blatty". I can tell a real difference in their sound from when I got the truck almost 2 years ago. I assume there is some amount of fiberglass packing in there which has degraded with time and use. The front half was hooked up with some welded in bends to make it fit with the rams horn manifolds. (casting numbers come up as Corvette, don't know if it means anything) It looks like the kit would work well with a set of headers, but I haven't bothered because I have a 4spd and it would be a pain. I was thinking about some different muffs, but I don't NEED them now.
