So 'James and Julie'  (sounds like the reading books I had at school)  ..oh sh*t that was Janet and John.... forgive me  ;D

What are the welds like?.. are they double skinned? ..whats the chrome like? ..where are the markings stamped ?... photos? How do they generally compare with the originals or late production oem.

Can't understand why CMS have them but DS don't if they are from the same manufacturer?

If they are OK I think I will hang on and get some from DS because I know that they will definitely let you return stuff if not happy. I know people who bought off CMS and had hassle returning stuff.

Cheers ... Ash

HM323 Update
« Reply #46 on: November 25, 2015, 09:12:23 AM »
First inspection is they're ok. Not Honda standard, but pretty good for the price.

Single skinned.

Welds at header / silencer interface seem good.

Drain hole in correct position and is larger than the oem hole by a few mm and isn't 'flared' just  a straight hole so probably less prone to blockage?

Marking convention is: CB500 'xx' 323 (where xx is IL, IR etc..).

The welded seams could have been finished better and do show some signs of 'serration' similar to the 350f pipes that Roy sent back. Not ideal but just about acceptable imho.

Pictures to follow in a few days...

Same old rubbish then. Serrated welds and single skinned?
DSS did say earlier that there were production issues, they are more picky than CMS about quality. I'd send them back, as they wouldn't do for me at that price. Although some may have no option but use them.

Must admit I am kinda agreeing with Roy.. something doesn't stack up as the HM341 factory DEFINITELY makes the  headers double skinned (look at pic previously in this post). How about this for a theory ... both CMS and DS have had production probs .. so CMS have, as an interim measure, got some from elsewhere.

interesting about double skinned pipes,

 I bought my set about 1992,all in Honda packaging,all with HM323 on them,
I have not had them off for a couple of years,but I am sure they are NOT double skinned,

if you check any photo ,all the pipes are blued,

maybe in the late 80's onwards they were into cost cutting ?

I think the way of checking is to see if there are spot weld marks near to the flange part of the pipe.

Wonder if this is any good ...probably not.

How about ceramic coating the inside of headers .. anyone tried that.

If find this all so bleedin' confusing ... I reckon those CMS pipes are 'stopgaps' till the DS/CMS ones are sorted out see below. The ones 'Coastpath' is selling must be prototypes of what's in the 'pipeline' from DS /CMS. SO both DS and 'Coastpath are saying double skinned but James's are single skinned from CMS?



Hi Ashley

Dear honda_four_rider,

Hi Ashley
They are double skinned - facsimiles of the originals as described.

Dear coastpath500,
Hi ... Could you post or add a link to a close up of the flanged outlet of the header pipe please so that I can ascertain if these are double skinned or not. The Honda OEM ones were definitely double skinned originally with 4 spot welds near to the header outlet.
Kind regards ,... Ashley

Hi Ash (again)
I can promise you that CMS’s headers are double skinned – I know this for a fact, I was working for them at the time of development and I asked an old colleague who still works there and he confirmed they are double skinned.
   
Cheers
James

You could always phone and ask? I am right though. Yes no spot welds, just superior welding. Speak to Gert Welvaar.
