Rob said teasingly:
Boy, you will do anything to get out of a little work, won't you! 
What can I say?
I do think the 2nd crossover was supposed to boost midrange torque.
Well, then I will see just how much difference it makes to my riding. I probably won't notice a thing!
Then Justin chimed in:
I like the styling of the Mac head pipes, I like the way they curve, go straight for a bit, then finish curving to the rear. I have Mac mufflers on two bikes and love the more rumbly exhaust note. I have never had any Mac headers but aren't they a double-walled construction? If so, say good bye to Beemer-blue header pipes. Also, if double-walled I would think the internal diameter might be a bit smaller than stock and might affect top-end power a smidge, if any at all. But, I usually don't know what I'm talking about so you are better off ignoring me like everybody else does!
Yes, the pipes do have an interesting curve to them. I'll have to check out the double walled construction. They do seem a bit heftier than the originals. I'd run right out and take a look at them, but I'm not running anywhere right now! It will be interesting to hear the new mufflers. I can't wait to get back riding. :-/
I think about the only difference between 1 and 2 crossovers is that it shifts the torque curve a bit.
Well, at least that's agreed on.
I think they will do very nicely.
