Frequently Asked Questions
What is included in the 1977-1978 Honda CB750K muffler set?
Four 405-style stock-type muffler assemblies are included—one for each cylinder in the CB750K four-into-four exhaust. Exhaust gaskets, collars and mounting hardware are not included.
Will the 405-style muffler set fit earlier Honda CB750K models?
It is specified for the 1977-1978 CB750K exhaust arrangement. Earlier systems can differ in headpipes, brackets and muffler connections, so do not assume interchange from appearance alone.
What should be inspected before fitting the four mufflers?
Check all four headpipes, eight exhaust half-collars, four cylinder-head gaskets, rear mounting points and clamps for damage or missing parts. Assemble the system loosely for alignment, then tighten from the cylinder head rearward without forcing the mufflers into position.
