Here's a 3rd design using even more of Jay's money: it uses two $750 2-stage Burns Stainless mufflers. The mufflers could even be offset left and right to improve tubing position.

pluses and minuses of that design;
Pluses: sides are kept separate, there is only one step at the exit, and it's a big one which sends the strongest possible return signal that can be used by cams w/ a decent amount of TDC compression overlap. There is a minimum of bends.
Minuses the longer the muffler the better for noise suppression, there is a lot of wasted territory where the external tubes bend around
