HI first post here hope it was OK to post this here. I bought a CB750F with a RC 4 into 1 exhaust. It look exactly like the one in the race bike gallery in this section that is signed, is this a good exhaust. Also the exhaust has two pieces by the flange that bolts to the motor, and had some kind of tape holding them onto the exhaust could you please tell what kind of tape this is so I could remount the exhaust. Thanks for any help or information Andy.
