I have a '86 1100 in a '86 braced Yosh frame. It currently has a Duplex system off of a ?91? (I think. It has been a long time...) 750 that sorta works but the exhaust sticks out at a funny angle and I had to modify the can for clearance. Are there years of pipes that will fit this combination without mods. I am having issues finding anything in good shape other than the V&H drag pipes.
