Requires exhaust work, is cross-under box necessary?

Hi Folks, recently bought a ยด78 CB400 Twin. Good condition but needs work. Both exhaust pipes and cross-under box/chamber are shot. Is it necessary to run the bike with the c-u box joining the pipes beneath the engine? Will the bike run normal without it? Thanks, Rob
