Exhaust fitment?

Need to ask if a KZ1100 Mac exhaust system will fit on a 79' KZ1000LTD Not sure what year the 1100 exhaust is from.

Kind of looked around for a thread that explained posible pipe swaps but found nothing. Would be kind of cool to have that info out there.

Thanks

for the record, I just proved to myself that a kz650 has the same exhaust pitch as a zephyr 750. My new pipe is from a zephyr 750 and fits perfectly!
