1975 Honda CB400F Exhaust System and Port Hardware

The exhaust parts that seal or replace the pipe are a black 4-into-1, a stud set with eight studs, a single port gasket, a ten-pack of that gasket, and a chrome clamp. A kick-stand stopper in this category is not a port seal.

1975 Honda CB400F · Exhaust Buying guide

System, studs, and the same gasket two ways

Buy the MAC system when you want a full black 4-into-1 that names this Supersport. Buy gaskets by the port you are opening. The stud set is hardware, not a muffler.

Quantity is the gasket choice

No bike total is printed for 18291-028-000. The single is one piece and the text says to order the quantity you need. The pack is ten of that same gasket, useful as spares, not a second shape. The chrome clamp is separate: 14-fin, 55mm center-to-center, and it does not say whether you get one clamp or more.

Leave the stand bumper out of a pipe order

95011-61000 is the kick-stand stopper. It sits beside the exhaust parts and it will not seal a headpipe. If the stand clanks, that stopper belongs with the stand. If the pipe leaks at the port, you want 18291-028-000.

Exhaust questions

Does the system name this year?

Yes. The MAC 4-into-1 names the 1975-77 CB400F. It is black, with a removable baffle, and it says the centerstand still works.

How many gaskets come in the single?

One. It is sold each. The ten-pack is ten of the same gasket, replacing 18291-028-000. No per-bike count is printed.

What is in the stud set?

Eight studs, eight washers, and eight flange nuts, titled for the 1975-77 CB400F. It does not include the port gasket or the pipe.
