Easiest way is to mount muffer first (note custom brackets in photo above). Once muffler is fixed in 3D-space, you can them make middle section that connects to header pipes.
I'm not fan of that conical adapter because it doesn't have positive seal with lots of surface-area. It'll leak unless it's welded to mid-pipe section as final step. Check out how stock and various aftermarket exhausts are desgined on pre-gen/new-gen bikes. I have comparison here:
https://www.ninjette.org/forums/showthread.php?t=338180 . Best solution is conical mid-pipe that continuously expands to muffler-inlet diameter as that'll maximize performance. Tyga exhaust is best for new-gens, makes most power-gains of +22% more than stock!
Some photos (ones that survived Photobucket purge) and videos of using that cone-adapter to fit universal mufflers to various exhausts. Stock and Tyga exhaust. Had to trim off tip of 38mm cone to fit Tyga 42.5mm exhaust pipe.
