CB750 EXHAUST HEADERS

[ADEEL MIRZA]

Any suggestions on the header size of CB-750 exhaust system? Currently I have 1-1/2" pipe headers. Can I go upto 2"?

There are no 2 inch pipes made. You could make your own i suppose but the mating point at the engine is still going to be 1.5 inches. Also a larger exhaust will mean slower moving exhaust gases and that map potentially have detrimental effects to your powerband. Of course, if the goal is to only look cool...
