1975 Honda CB550F · Exhaust Seals & Mounts Buying guide

Build a headpipe service order by component

A port seal, finned clamp and stud kit are separate purchases. Inspect the joint being opened, count the pieces required and compare the mounting dimensions before choosing hardware for an original or replacement exhaust.

Buy seals for the ports being opened

The featured gasket pack contains ten port seals for repeated service or keeping spares. The linked individual gasket lets you order a smaller quantity for the repair. Match the listed references with the cylinder-head sealing joint; these port gaskets are not generic seals for every muffler or collector connection.

Check mounting condition before assembly

Inspect the studs, nuts and clamp mounting for damaged threads, corrosion and distortion before ordering. The replacement stud set and finned clamp are separate products with different contents. Follow the Honda manual for repair and tightening procedures rather than using new hardware to compensate for a damaged mounting point.

Common buying questions

Do these gaskets seal the headpipe or muffler joint?

These are exhaust-port gaskets for the headpipe connection at the cylinder head. A muffler or collector joint is a different location; compare that joint’s own seal and mounting specification instead of substituting a port gasket.

Does the stud set include the finned clamps?

The hardware set contains eight studs, eight washers and eight nuts. Finned clamps and exhaust-port gaskets are separate choices. Compare the condition and dimensions of the fitted pieces before ordering for the complete joint.

Can I buy fewer than ten port gaskets?

Yes. The individual exhaust-port gasket is linked here and is sold one at a time. Order the quantity required for the repair; the featured ten-pack is an alternative package for service stock or multiple jobs.
