I have just found a suppertrapp pipe for my 1985 Honda Nighthawek S, I'm chomping at the bit to hear what it sounds like! Would it hurt the bike to put it on without rejetting right away?

Normally not, as long as it is has the, standard equipment, 1.5" baffle (if it's a Kerker).

If it is a SuperTrapp with the disc assembly it can be "tuned" to the stock machine (controlling the exhaust flow) by adding or removing discs.
