Turns out it’s a Motad system. Aftermarket stainless, but on the cheaper side of things. Had a go at making one that’s a little less shit.
Two little sections of pipe the same width as the primaries, cut at an angle so they just meet each other. Bit fiddly, but overall not a great deal of work.
All welded up :) not particularly pretty, but hell i’m not selling the thing. Here’s the inside. So much better it’s not even a contest, and this is just my amateur efforts!
I’ll debur it and perhaps clean up the inside somewhat with a dremel if i can find a bit that isn’t made of butter.
My brake light also came in the post so i chopped up the rear frame a little to integrate it nicely :) bugger to weld and a lot of grinding with aforementioned butter-dremel. Worked quite nicely though :)
Oh, and i’ve got the swing arm dismantled too. Working on bikes is easy!
Work time: lost count now. Maybe 2 days? 3?

Certainly looks like it’ll flow better than before.

Great work! Your exhaust looks way better than that aftermarket one.
Also I’m guessing the Dremel bits made out of butter is part of their business plan. When building a car at university we had Dremel as a sponsor, and even then they would limit the amount of bits we got, while they knew damn well they are worn down or broken within a few minutes.

Thanks man :) I’d have had to try really hard to get something that would flow worse than the aftermarket one ;)
You know I hadn’t considered that butter-dremels might be their business case ;) make them last just long enough to do one job, but give up mid-way through the second so you have to buy another one. Genius!

Yeah, you need a real die grinder if you’re working on steel. Fortunately they pretty darn cheap at harbor freight.
