81 cb750k exhaust

[WonWonrides84]

Will the motogp werks exhaust system work on a cb750k dohc? Or do they only make them for SOHC cb750's? Also, if they do work on a 81 cb750k, where is the best place to order it from?
TIA

Not sure about the MotoGP system, but I put a Delvic on mine and it sounds incredible. Very pleased with it.
