I was thinking something like this, but with 2 round silencers spliced together, one above the other, to create a figure of 8 shape, so a bit curvier than this, fitted further forward with long tail pipes.
Half a dozen XSs at the show, most with straight through pipes. No idea how they sounded of course, but I'd like to try my new ones first before I start cutting into them.

 Smiley I'd really hoped to be riding it to this show. Worth taking the time to get it properly sorted though.

Tom dropped off my order of XS parts today, (we put in a joint order to the German suppliers).
New clutch wormdrive, (connects the cable to the pushrod), new pushrod & new springs. Now I need to drain the oil, remove both side cases & fit it all. If that lot doesn't fix the dragging clutch, nothing will -no, it's not just cable adjustment.  Smiley
Also bought new wheel spindles cos both of mine are pretty battered, & new exhaust gaskets.
No room to work in the lock-up garage any more, (Mr Loon & I share it & he's just bought a car engine & gearbox), so I need a dry day so I can do it outside.

Also nipped over to Torque Technique in Salisbury, Wiltshire after work this afternoon & collected the new stainless exhaust pipes. Haven't tried them on the bike yet cos I was still in my Post Office uniform & didn't want to get too grubby, but they look like a pretty good match for the old ones. 220 quid cash.

The old ones were 1 1/2" O/D, but they couldn't match the bends in that size cos I'd made them from 2 different pieces welded together so that the radius changed half way round the curve. So the new ones are 1 5/8". Fortunately the finned exhaust clamps still fit. I need to find some stainless washers the same size as the ports now to make flanges.

I mentioned baffles & they said they make cone shaped ones from perforated stainless tube. About 6" long, with the small end about 3/8" & the large end the diameter of the pipe. They don't quieten pipes fully but do change the pitch. Might be worth experimenting with. They gave me an offcut of perforated tube to try.

Their 65,000 quid mandrel bender. Each size of former costs 500 quid. They can form up to 3" diameter pipe.
Not cheap, but a good product & very fast turn around.

Precisely.
Nipped over to Berkshire after work this afternoon & collected the fuel tanks from the welder. I took mine over to have a new breather pipe welded to the underside. So while I was going, Tom gave me his to take as well cos it was leaking.
Turned out his was leaking in 3 places, not the 1 he thought. Fixed with a mix of welding & silver soldering.

I supplied a length of 6mm bore steel tube, which I'd rolled a 90 degree bend in, to replace the original breather pipe, which I'd stupidly cut off flush with the underside of the tank. It pointed straight down & would've looked 'orrible with a breather pipe on it cos the tank sits quite high. Unfortunately, as soon as we put fuel in the tank, the fumes lifted the edge of the paint around the hole.
So BKI Welding in Newbury, Berkshire silver soldered the new pipe over the old hole -they couldn't weld it cos the original joint is brazed. It now points back down the tank, so the breather pipe will run along under the tank & drop down the back of the engine. Should've done this to start with, but didn't think it through, obviously. Now the tank will need cleaning up & repainting.
Both tanks sorted for 25 quid cash, so £17.50 each.
