Refurbishing Jota replica silencers

I am finally getting around to rebuilding my long neglected '79 1200.  It hasn't moved from my shed since my last ride (great rip to California) in Oct 2012.

There are a ton of things that need attention on it - and one of them is my exhaust silencers.  They are the Campbell replicas of the Jota units, but the chrome has started to flake off on the them.  One thing that has always bugged me about these silencers is the ugly seams where the welds are - unlike the seamless ones of the original Jota silencers:


Since they need to be re-plated anyway, I was wondering if the weld seams could be ground down to appear more like the originals... anyone ever tried that?  Would that likely result in a weak spot at the seam?

I also have an inquiry into Malcom Cox to see about just getting a new set of his silencers.

Thanks,
Andy
 
Hi Andy,
I can't say I have relevant experience here, but if it were me, I would not grind the seams.  It seems impossible to have an accurate idea of the weakening of the seam or lack of weakening.  That being the case, how would you feel if you went forward and ground, polished and rechromed the silencers, only to have the seam split shortly thereafter? 
Save your money and go with quality new ones!
 
Lawrence - I think you may be right.  I just got word back from Malcolm Cox that he has the "seamless" silencers in stock.  I will probably go that route and then try to sell the Campbell units to offset the cost. 

Any snow yet down in Idaho?

Cheers,
Andy
 
Andy,
Check with Wolfgang as well, he has seamless stainless Jota cans in stock, have bought dozens from him and they are very nicely made.
Plus he is just up top in Canada

 
Andy, hard to get anyone to rechrome used silencers, they don't want the contaminates from the mufflers in their tanks. You might get them to do it if they are about to change the chemiclas in the tanks out. 
 
Hi Andy,
Snow?  Are you serious?  We're in the midst of the best of seasons for riding!  Not too hot, not too cold.  Just like Baby Bear's porrage!  Last weekend I had a glorious ride through the mountains, canyons and plains for SW Idaho and Eastern Oregon.  There is no finer way to spend a weekend!
Now, up in the higher elevations you could feel a chill, but down here in the valley - just perfect!
