The insert fits a pipe with a 1 3/8-inch inside diameter; the glass-pack body measures approximately 1 1/4 inches. It is listed for the M.A.C. drag pipes used on 1977-1978 Honda CB750K models.
One insert is included for one individual drag pipe. A complete four-pipe CB750K M.A.C. drag system requires four inserts when fitting every pipe.
Secure it with the intended retaining method, verify that it cannot move into the exhaust or contact moving parts and recheck the fastener after the first heat cycles.
