In the ongoing attempt to get the 919 Moriwaki cans to fit my Superhawk, it seems as though most aftermarket mid-pipes would more than likely work. I have tried to find a way to make the 919 parts fit but the bend is wrong and not long enough.

 

Get some pictures when you done

 

Post up some pics and measure the I.D. and O.D. of the muffler inlet. Any aftermarket superhawk midpipes could be made to work, but preferably find ones that have a matching size diameter for the muffler inlet. Also some have spring loops and some don't and use a clamp. I'm assuming yours use 2 springs each? A stainless midpipe with spring loops is probably your best bet. If they don't fit already you could easily have a shop slighty expand the end of the midpipe to fit. Jardine makes them still out of stainless or plain steel with the 2 springs loops-give them a call I know they sell them separately (at lease they did last time I checked). Two Brothers are also stainless with the loops, though I'm not certain if they can still be bought new. And the list goes on...

 

I have a spare set of midpipes like new from the two bros system I had, let me try to dig them out this week
