    I had an interesting conversation with Pete Manley one of our new members, we were discussing exhausts and I happened to mention that I had been told that all of the genuine downpipes were twin skinned. He said that he believed that his were original and that they were only single skinned. Could anyone shed some light on this for us?

    • I just checked mine, that I know are original U.S. spec, and they are single wall.

    • My 1961 CB72 has double skinned exhaust downpipes....from memory.

    • Both

    • I would be interested in a comment from Chris Bancroft

    • I believe all were double skinned in GB although according to my wife, I am sometimes wrong !!!!!, my CB77 has double skinned down pipes as does my CB450 Black Bomber

    • Thanks for that Chris Bancroft. Is it obvious if they are?
