Unlike with all my other exhausts, I didn't start this one from scratch, but used the downpipes of a Triumph Trophy 900. They are spaced correctly, but hang a bit low on a normal XS 750 and the left downpipe would go straight through the sidestand mount. Oh and they're coated in black, even though they're actually stainless. What you don't see in those pictures are the two hours of polishing to remove (most) of said coating.
Next step was to alter the frame a bit. There's a through-hole on the right side for mounting the exhaust, but a stud on the left. The stud had to go and in order to do that concentrically I quickly knocked up a little guide with a 6mm drilled through and a 12mm opening on the other side.
Drilling the hole took quite a bit of time, but other than that was pretty straight forward. (Sorry for the bad picture quality!)
Luckily I had some left-over exhaust hanger plates originally made for the TR1, which only had to be drilled out to 12mm.
As the silencers originally are made for 45mm exhaust pipe, I had to get some step-downs and then it was "pretty much" just a case of connecting the dots (ends).
Now what does it sound like? Rather fruity, if I may say so...
Next step will be some finishing touches to both the subframe and the sidecar frame as I am a bit unhappy with the top rear mount. Once that is done, I will shift my attention towards making those Mikuni VM36 work!
