MAC performance 2 into 2 Reverse Cone Exhaust Part # MAC -22-Y650B

That's a shame as they were a unique, reasonably priced system. As Halfmile mentioned Gunn & Jemco will perhaps make you pipes. I have a set of Gunn Design (attached); top-quality, but expect to pay in excess of $1K. I haven't dealt with Jemco - they have the capability (see website).

Another option is back to the MAC knowing you'll have to re-fabricate the left head pipe: not too difficult given tools and a "builders kit" (that includes pre-bent pipe sections to weld), just make sure the kit pipes are the same diameter.

TC Bros has a 1 1/2" builders kit with flanges for the XS650. I use Speedway Motors combo bends in 1 5/8"
