Thanks Oddjob for the information just ordered a set, after checking with Silvers who said they do not currently have a delivery date. I wished I had bought a set last year and didn't want to miss this opportunity of getting one this time.

Gents, can you confirm these pipes fits well onto original brackets?
I'm thinking also to order them..

Bit hard to answer that as I suspect none have probably taken delivery yet. :o

In my experience the ‘repro’ pipes (not from this latest batch of production) you do sometimes have some fitting / alignment issues - even with original Honda mounting brackets.

But, given the lack alternatives (or lack of OE pipes) it’s a small compromise - and you will just need to ‘massage’ them into place.

If I needed HM323 pipes I wouldn’t hesitate and suggest you get them before they sell out as they inevitably will...

I seem to remember a couple of guys had some issues with fitting, BUT it turned out the bikes concerned had been involved in incidents/offs where the footrest mounting loop (which is also where the silencer mounting bracket fits) had become slightly bent inwards. Chances are if you have difficulty with them it's probably worth checking, as a lot can happen in 40+ years and several owners.

My experience was based on removing genuine (near NOS) Honda HM323’s and fitting the repo parts to the same bike (transferring the brackets across). The fitment was definitely subtly different and tolerances on the repro set were nowhere near Honda standards. But, they were excellent quality imho (felt much heavier than the genuine parts as well, so I assume used a slightly thicker grade of material in their construction).

I wouldn’t hesitate in getting them personally if I needed them and let's face it they look superb....

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

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?

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!

The new exhaust system has arrived so I set about dismantling the current one in the hope of recovering some cost by flogging it only to discover that my totally original four pipes are mainly composed of non original filler and silver paint. Even I haven't got the nerve to put a price on this collection. However the four down pipes look like they would be in a useable condition and if anyone with a hacksaw would like to collect or arrange to collect them then they are yours free and gratis, otherwise they go to the tip when it finally reopens. 8)

Not being in engineering or the scrap metal market they're of absolutely no use to me, and I really can't be arsed with the aggravation of selling crap on ebay so my offer still stands. :o

Thought about the suggestion of posting my collection of grotty scrap on eBay and did, and so if anyone wants some reasonable down pipes that's the place to find them.

One thing about the pipes CMS sent; one sounded a bit off and it was promptly replaced, no argument. Happy days!

When they arrive and you've got them fitted etc can you let us know your impressions please Erny. Not fitted mine yet and won't for at least a year.
I do not plan to fit them either, just buy to keep them for later use...

My experience with fitting was that they fitted fine even with the aftermarket brackets I sourced from Italy (can’t remember supplier but way cheaper than DSS or CMS.

My one gripe was that the position of the main stand rubber was out and I had to make up a small extension piece

Been on the bike for 3 years and no degradation of chrome etc

When you see what you want, put it in your basket. That will normally “reserve “ it until you pay.

Some shops put a timeout on the basket to stop this.

I had it in backet last night but this morning it was out. I understand that... especially for such hot product.
My mistake I should be ready to complete order. Maybe if I keep session (log-in) active it won't happen

Not surprised Erny. I would imagine their timeout is about 15 minutes. Time for you to select a few other parts.

My shop is set to 5 mins as we sell advanced motorcycling training courses and they are in high demand (at least they were…)
People would reserve 4 or 5 different dates in their basket, thus removing them
From inventory for anyone else to buy.

Erny, I got a set last night - just gone on the CSML 500 page and its showing available? Get on it quick!
