There is also the option of this MAC Tri 'Y' 4-2-1 from Niche Cycle at $335 but it doesn't include a silencer.
Kawasaki KZ900/1000 Tri-Y Black 2.5 4-Into-2-to-1 Exhaust Header Head Pipes

 

That MAC is just there 4 into 2 head pipes stuffed into a straight pipe, probably no goilet so velocity would suffer. MAC are cheaply built and don't use proper collectors or splitters. I have a few of those head pipes so I know how they are built.

I guess that is why the Hindle is so much more money, your paying for proper design, engineering, and materials.
