Does it not fit at all? I've been curious.

The HDs have the dual in single out muff. So the pacesetter y making it into a single exhaust doesnt work.

What he could do is buy the pacesetters and y and buy a catback for a 5.3 truck.

Yeah that I know (physically), I mean if you junked all that factory 70mm piping and went to a single 3"... would it then fit up in there?

Yes, the single on the HD makes a huge difference apparently from the few that have been smart enough to do it.

My friends 2500hd has pacesetters, ory and a GM performance catback for a 5.3 truck.
