engines and frames are the same, as with the swingarm etc., the
pre '99 2in1 Exhaust will fit the injected bike for sure.
only problem could be the different position of exhaust-can mounting
points on both frames, nothing a homemade bracket couldn't cure.
I'm going through the same thing with my carb 750ss. The 900 pipes will bolt up, but it's not the best fit. The stroke on the 900 is longer, so the pipes hang down more than they should. I bought a 900ss header pipe and ended up having it cut up and welded and I'm still not happy with it. I found a old set of 2-1 staintune headers for my bike that are on their way to me now. I already have a "universal" carbon can--I am going to take the whole mess to an custom exhaust place to have them tie it all together. Finding a 2-1 system for a 750ss is going to take some time. If you really want that look, you might have to buy a system like the one posted above and plan on doing a little fabricating........
