1979 Honda CB400TI Hawk I · Exhaust Buying guide

Work through the exhaust one joint at a time

Identify the parts being retained before ordering seals or a muffler. This is especially useful on a Hawk I with a changed exhaust, where a model-year match cannot establish every joint now on the motorcycle.

Avoid grouping every seal into one gasket type

The port gasket is offered individually or in a ten-pack. The headpipe joint and crossover use separately identified seals. Keep the removed parts and their locations distinct while building the order, particularly if the exhaust has been changed from the original arrangement.

Plan a muffler order by side and connection

The chrome slip-in muffler is sold individually and can be used on either side. Its adjustable slide bracket is included. The linked crossover gasket is specified for its original-box connection; verify the exhaust still uses that arrangement before relying on the seal choice.

Common buying questions

Does a ten-pack contain the different seals for one exhaust rebuild?

It contains ten exhaust-port gaskets. Headpipe joint and crossover gaskets are separate products for different connections. List the joints you are opening first, then choose the quantity of each appropriate seal.

Can I order the slip-in muffler for a changed exhaust?

Check the actual inlet arrangement, mounting position and clearance against the muffler before ordering. Its stated Hawk I application assumes a suitable slip-in connection; a replacement header or collector can change what is needed.

If both mufflers need replacement, is one order quantity enough?

The muffler is sold individually, although the same product can serve either side. Replacing both requires two mufflers. Check the sealing and mounting requirements for each connection alongside the muffler order.

Not sure which part you need?

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