I have seen a set on a 85-86 3/4 ton, I think it was a hd 3/4 ton though. It had factory dual exhaust 2 or 2.5 in don't think it had any catalytic convertors. The exhaust tubing also had like a heat shield around the exhaust pipes. Kind of like the heat shields on a universal catalytic convertor. I'm thinking the engine was a 350, th400, 14 bolt ff rear. I was looking at buying it but that was a really long time ago. That is the only truck I have seen them on out of all the engine bays Ive seen.
