How interchangeable is the exhaust between the current Softail models?

I like my stock exhaust on my 13 FB Lo- except for removing and installing the rear wheel. Long story short - **** shotgun exhaust and removing both mufflers and the bracket to remove the rear wheel. I don't know if I can even do rear brake pads without taking off both mufflers and exhaust bracket.

I think a stock Heritage exhaust would work -floorboards alike. Would a Breakout system work?

I know nobody cares about stock exhaust - if I can get removing the rear wheel down to one muffler removed max -and saddle bag options expanded

If I do aftermarket it will be 2 into 1. Comments, suggestions welcome
