I don't see where you'd run into problems doing exhaust work with a 4-post vs. a 2-post. Unless you're trying to change out a full-length system on an extended bed F250 or something that sticks out over both ends. (But if that was the case, you could just lie on the ground and swap that bad boy out without a lift)
