1972 Honda CB350F0 · Exhaust Gaskets & Clamps Buying guide

Build the hardware order from the front joint to the mufflers

Port gaskets provide the seal at the engine, finned clamps locate the headpipe mounting, and the tube set serves the stock muffler connection. Keep these separate roles clear when comparing packages.

Order sealing pieces independently of clamps

The finned clamp is a mounting component; the exhaust-port gasket is a separate product. A new clamp does not establish that the old gasket can remain in service. Inspect the joint and use Honda’s repair procedure to determine which sealing and fastening pieces should be renewed together.

Compare package scope at the muffler end

The connecting-tube package already includes its band clamp and screw, unlike a separately purchased headpipe clamp. Two tube sets are specified for the original system. Record which joints are being repaired before buying so the order does not duplicate included bands or omit separate port seals.

Exhaust Gaskets & Clamps questions

Does the chrome finned clamp come with an exhaust gasket?

The clamp and port gaskets are separate products. Choose the appropriate gasket quantity alongside any clamp replacement required by the inspected joint, rather than treating the clamp listing as a complete sealing kit.

Should I buy single gaskets or the ten-pack?

Both carry the same replacement references. Singles suit a limited repair; the ten-pack is useful when you want spare port gaskets as well. Buy according to the positions being serviced and the spares you actually need.

Which clamp is included in the connecting-tube set?

It includes the band clamp and screw for the original muffler connecting tube. The finned headpipe clamp is a different component at another joint, so compare the repair location before choosing between them.
