1978 Honda CB400A · Slip-in Muffler Buying guide

This muffler measures 23 7/8 inches long and 4 inches in diameter. An adjustable slide bracket is included. Compare the retained exhaust and surrounding clearance before selecting the quantity or planning a replacement for a modified system.

Work from the existing collector connection

The replacement is intended for a slip-in inlet, including suitable CB/CM400-style arrangements. Inspect the collector and connection already on the motorcycle. A previous owner’s replacement exhaust may require a different muffler even though the frame is still a CB400A.

Plan the mounting and quantity

The supplied adjustable slide bracket allows the mounting position to be matched to the motorcycle. Check its alignment and clearance before installation. Each order is one muffler, usable on either side; replacing both sides requires two individual mufflers.

Slip-in Muffler questions

Is this a pair of mufflers?

No. It is sold individually. The same muffler can be used on either the left or right side, so order two if replacing both sides of a suitable slip-in system.

What are the dimensions and included mounting part?

The muffler is 23 7/8 inches long with a 4-inch body diameter. An adjustable slide bracket is included. Compare these measurements and the mounting position with the existing motorcycle before ordering.

Is this a universal clamp-on replacement?

It uses a slip-in inlet. Confirm the current collector or pipe accepts that style before ordering, particularly if the original exhaust has been replaced. Do not infer compatibility with a clamp-over connection from the chrome appearance.

Not sure which part you need?

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