Well this week alone I've ordered a set of repro pipes, a NOS tacho for a CB550F2 as I have those clocks fitted to my 500 and just bought a NOS seat on E-Bay. Been an expensive week.

I think I know whose seat that was Ken ... seemed a good deal for NOS

Just looked on the CMs site and it seems they are sold out already, this also includes the individual pipes they had on sale for €600.00 each! >:(

Silvers have sold out of the CB750 no-number HM300 pipes from Yamiya as well... https://www.davidsilverspares.co.uk/CB750K0-FOUR-1969-1970-USA/part_217721/

The exhaust system arrived this morning, all in one box unlike the genuine Honda system which were in 4 separate boxes. Quick service especially with the virus around etc

Will open it shortly to see what they look like, will report when I have.


Well just opened the box and checked one of the exhausts. The large box contains 4 separate boxes, exactly like the Honda box. There is a note inside the box saying that the entire system has been test fitted on a jig to ensure it fits. Inside the separate box is the exhaust inside a large bubble wrap bag. Word of warning here, the box is sealed with very large brass looking staples, I've removed them all as when I was putting the exhaust back after checking it I caught the end of my finger on the 2 I had left fitted and almost ripped my fingernail off. If it can do that there is also a chance they can scratch the chrome of the exhaust so remove them all and reseal with tape is my advice.

So how's the exhaust look, in a word, brilliant. Chrome is very deep and TBH better than the Honda chrome, no marks at all on the one I've checked and unless I come back and say so that would include the other 3 as well. Clearly double skinned headers. Unlike the Honda exhausts the chrome covers the reverse side of the exhaust section. Honda left this a sort of partial chrome, very dull and I ended up spraying my originals with zinc paint in order to protect them better. The chrome on the reverse side is as good as on the outside section. The exhausts have the warning imprinted onto the reverse like the CB550 US version. This exhaust has the main stand rubber mount and even that is brightly chromed.

In short this is an exceptional copy, IMO better than the original and I know that's saying something. I really can't fault it, how it fits will be the test though and that won't be for a GOOD while yet. Maybe someone else who has bought this new system can give more feedback on that. I know the old CMS repros had a few problems with fitting so maybe they have corrected them for this production run. Hence why I'd like someone who has bought one after me to say how they fit.

This is great news!
Last thing I'd like to know how they sound compare to OEM originals?

I sold my NOS copy of the 500K seat for £450 so this was a bit of a bargain. I may end up selling it again as I want a perfect copy of a K1 seat made but in genuine leather not vinyl. If I get that made I’ll end up selling this one.

The seller did say he comes on the site but doesn’t post often

Received my exhausts this morning, only just had time to open the box. Really pleased with them have put some pictures below so everyone can see them, although the pictures aren't great.

Hope these help people form an opinion, I did not get any instructions with mine although the cover letter says there should be some.

These look far superior to the last batch of repro pipes. If you got in there quick - assuming they fit well - congratulations!

I'd advise both yourself and Erny to go to the place where they are listed and do what I did, ask CMS to contact you when they come in again. At least that way you'll know before most people.

I found a very small fault in one of mine and by small I do mean small. As I was inspecting one in the sunlight I heard it start to rattle, clearly something was inside the exhaust, the more I shook the exhaust the more the noise started to go toward the back. Eventually a very small blob of weld fell out of the link pipe hole, looked like a very small ball bearing. It would have probably blown out when the engine started it was so small and that's the only thing I found on all four of my pipes, the chrome is REALLY excellent, best I've seen in a long while. Don't know who did it but kudos to them.
