1982 Honda CB450TC Exhaust Gaskets

Choose exhaust gaskets for your 1982 Honda CB450TC by the joint being serviced. Port gaskets, headpipe-joint seals and crossover gaskets are distinct products; identifying the location first avoids buying a familiar-looking seal for the wrong part of the exhaust.

1982 Honda CB450TC · Exhaust Gaskets Buying guide

Three sealing locations, three different choices

Use the existing exhaust and its service information to identify each seal. Individual port gaskets and a ten-pack address quantity needs, while the joint and crossover products have separate replacement references.

Separate the port from the pipe joints

The port gasket carries references including 18212-634-000. The headpipe-joint gasket references 18391-413-000 and 18391-413-010, while the crossover gasket references 18392-413-000 and 18392-MG7-750. Keep those locations distinct when planning a repair that opens more than one exhaust joint.

Order quantity for the work planned

The featured port gasket contains one piece and is sold individually. The linked pack contains ten exhaust-port gaskets with the same listed references. Select the sensible package for the work; a ten-pack is a supply quantity, not a statement that the motorcycle needs ten.

Common buying questions

What is the difference between the single gasket and ten-pack?

The individual product supplies one exhaust-port gasket, while the linked pack supplies ten. They carry the same listed port-gasket references; choose the quantity needed for your repair or workshop supply.

Is the headpipe-joint gasket the crossover gasket?

No. The headpipe-joint product and crossover product have different listed functions and references. Identify the actual joint being opened before choosing between them, even if their shapes appear similar.

Can I select seals by model year after fitting another exhaust?

Check the changed exhaust first. These model applications do not establish the dimensions or sealing arrangement of every aftermarket system, so match the joint and required seal to the parts fitted.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
