Minor encounter with the road resulted in the right end can on my small cans being damaged.
Need to replace the damaged can with an errr... more capable muffler end can.
As it's broken a wee bit less noise could help make the effort worthwhile
Just diy it ? as would seem obvious
or are there tricks/secrets to this from others who have done this previously?

My LC pipes are custom made with hand made cans.
All you really need is some ally tube, and some steel tube with punched holes, or flat with punched holes that you can roll.
They came up okay, but could be done better if you want more bling (Using ally end caps etc).

You might also be able to salvage the end caps etc off the old cans, so all you need is the ally sleeve and steel centre.

Can't you take the ally tube off and then hide the bad side where nobody see it?
Btw, it sucks to scratch the bike. My bike fell in the barn and the radiator got squashed and a mounting flange for the plastic radiator protection bent.
I think the whole radiator got bent/twisted a bit. 
One time i crashed when i went too fast up to the house. But it didn't happen anything at all with the bike, (and i missed a big rock sticking up through the grass by half a meter  phew!) there was just a massive ammount of dirt stuck around the bike. You couldn't even see the gear lever because of the big chunk of lawn. Well i lol'd and quickly f**ked off and hid myself for a couple of days, i think my neighbour saw it.

Hybrid; those look 'fine' by any yardstick.
Thanx gents ..
even though having located replacement Microns, I'm thinking that a wee bit less noise could be worthwhile.. not a lot of profit in advertising ones' location to the local constable at all times
Surprisingly, to me, my mounted pair of Microns uses a stinger inside the rear cone design.. which in itself significantly reduces noise.. meaning then that the 'small can' bit is essentially ineffective... as these seem to get noisier as one gets used to owning them.. (reducing noise tolerance?) they work Fine as chambers though
Any pointers on How much of a
step up in diameter the perf tube should be from the stinger diameter ?

I would have thought you would want the internal diameter the same as the stinger.

Dunno? I've never built End Cans before.
But I recall reading Mr A Graham Bell suggesting a size increase for the perf tube bit. Restrictions increase the retained heat.. good to a point for power but there's aleged risk of keeping piston crown temps too high.
That's all I know about it... and why I asked. Guess I'm going to re reading tonight.

Actually yeah that sounds about right.
The perfs would also create some turbulence which would create a restriction.
The TZMike cans I have on the 500 project are a fair bit bigger internally than the Nikkon stinger size, but I thought that was a fair contributing factor to them being so damn loud.
