Cycle X DOHC 4 into 2 Exhaust System

Cool exhaust systems for DOHC models are few and far in between. Our 4 into 2 System provides style, performance and great sound in one package. Features a slight upsweep at the rear of the mid pipe and has a mounting bracket on the backside of the muffler to attach to the rear foot peg mounts. Use your stock finned clamps to mount these awesome head pipes or get rid of those rusty old things and use our billet mounting flanges found at the bottom of the page! Chrome and different style options to come!
Fits 79-83' CB750 and CB900
