Cycle X BRAND NEW Stainless Steel CR Replica 4 into 4 Exhaust (Head Pipes Only)

NOTE: The last two pictures shown above with the pipes and mufflers are for reference. (Head pipes only)

Check out the stainless 4 into 4 CR replica exhaust builder head pipes (add any mufflers you like).
This exhaust system is our Cycle X version of a CR 4 into 4 and is not intended to be an exact copy of the original CR systems or OEM systems.
We mentioned that these exhaust systems were builder pipes because the mounting of the mufflers will be decided by the person building the bike. Rear sets, cafes, bobbers, customs and the removal of OEM exhaust mounting frame areas is why we try not to use the phrase "bolt on".
These exhaust systems and head pipes are also popular in the custom, chopper, bobber, brat and rat world.
On the other hand, the system comes with brackets and hardware to make mounting the pipes easy for semi skilled people.

Our bends are second to none and the exhaust flanges are 1/4 inch thick stainless to reduce bending when tightening.

Stainless head pipes.
Stainless 1/4 thick flanges.
Misc mounting hardware.
4 copper gaskets.
Bolts.

Fits 69-78 Honda CB750 SOHC and 79-81 Honda CB750 DOHC.
