Dommie Silencers

Posted by Barry Robinson at June 14. 2017

The silencers on my 1959  99 apparently date back to the early eighties and I need to replace them. They have a protruding seam along the bottom and I have seen on the market replacement silencers like this but there are also very similar silencers available which are slightly smaller in girth and which  have no seam.

I have no idea whether the silencers on the bike are the originals or some throwback pattern part.

Could someone please advise as to which type is correct for my model and year. Thanks.

Barry

PS when I approached a well known exhaust system manufacturer and retailer I was only offered the slimmer seamless type.

Good Morning Barry,  There is a good thread on different types of Dommie silencers raised by John Sunderland on 28 Nov 2016.  Well worth a read (and images to consult) before you go much further - tho' it's best to ignore the stuff about Manxman ...... it may confuse the issue which of course, it is meant to do.  Regards, Howard

Hello Barry now as far Has Norton twins   Silencer go the  Frist sets from September 1957 to the Smooth look were Seamless on the underside of the silencer and the originals were made in house At Bracebridge Street Workshop by their skilled workforce.  I have a left-hand side Original  smooth look silencer succumb 1958  All aftermarket silencers have been copies of copies and it was Armours Silencers  that put in the seams on the unside  has they did not have the right tooling and contracted the job out to a silencer manufacturer  the end result was a seamed inside silencer  and  all Norton owners from then believed this was the original ones, which was not the case, and  No  one has ever  remade the Norton Manxman 650 silencers,  this motorcycle had its own set .   Now if you require the silencer I have you can  buy it from me at a fair price,     yours  Anna j

Thank you Howard. I did do my research before posting and had read the thread you referred to with interest. Unfortunately as a newcomer to all things Norton references to Peashooter, cigars, cheroots etc were essentially meaningless to me which  is why I used the possibly too simplistic distinguishing feature of the seam or no seam. Also the models mentioned in the thread were 1960 or later ( slimline; there I have learned something) whereas my 1959 is a wideline. But is that material? Answer is I don't know and I'm no wiser.

Thanks again and to Anna and I am sorry if I have asked a question to which there is apparently no simple answer. When I am told by some knowledgeable stranger that my newly restored Dommie is sporting incorrect silencers I shall have my suitably rude reply ready.
