What style are you looking for? Steve Maney still has some left, his are still the best out there.

Nigel at NRP Exhausts also makes similar but in stainless steel (or titanium) but needs the bike to custom build the pipe.

Will make you whatever you want. Custom fitted to the bike. As will NRP, who made the separate pipe stainless exhaust on my Rickman.

Though I see little benefit in fitting any exhaust to a road bike that will require the removal of the centre stand and need at least partial removal to do an oil change, and not use peashooters!

But, I think the Commando separate peashooter is system is the most beautiful exhaust around, so I may be biased.

FWIW, I looked into the Viking system some years ago and decided it wasn't practical for me due to the required removal of the center stand and the reduced ground clearance. But if these items weren't a consideration - and they may not be for other folks - the Viking looked like a nice piece of kit.

Lurgy, why do you want one ?

Trevor Hallam · Friday at 7:29 AM

I don't have this bike anymore, but I still have this 2-1 pipe set. No muffler, just the pipes. Its a system made by Armour in the UK. It worked great, but I prefer the stock setup so I'm not sure I'll put them on another bike. PM me if you're interested.

Hey Trevor, interesting bike….lots to look at

. Did you make or buy the central oil tank ? Where’s the battery live ?

Trevor Hallam · 2026-03-09T06:54:20-0600

I have to admit none of it was my work. The oil tank was made, and a very small battery lived under the seat hump. It was a lovely bike and lots of fun.

I will try to make a two into one pipe for a project. As i look at various siamese exhaust pipes such as these BSA ones.

It looks as if the cross over pipe is twice as long as the other pipe at the connection point. Am I seeing this correctly? Any other advice?

Hi Trevor, thanks. The more I look the more I like…

For a 360 degree twin, both primary pipes need to be equal length
