Perhaps, but how much of a measurable difference does it make? That may be a hard question to answer, since the measurement is on a Dyna, which isn't going anywhere and therefore not subject to airflow as if you were on the road.
I suppose we could nitpick back and forth as to how much difference the Heavy Breather really makes over a high flow air cleaner. In the end, I'm not sure that it's really enough to be a concern to most riders (not racers). I think it honestly boils down to a matter of taste, and there's nothing wrong with that.
I do like the look of it, though.

sure would, nice improved throttle response, couple extra hp and ft-lbs torque. I run a RSD venturi intake.

Every bike is different and some will see improvements while others wont. Same thing with big city thunder baffles making more hp/tq. Me and a bro had the same set-up including pipes & heavy breather, both of us have '07 fxdc's except I use the bct baffles and I pulled 2 more hp than he did. With the x-wing claims of increased hp/tq why not try it to find out, it comes with a 100% money back refund if your not satisfied and all you would be out is your time installing it if you do return it. After all 1 or 2 hp isn't really noticeable anyway but every bit helps. my.02
