Tracen and Lance at Gretna Cycle did a fantastic job, only got to ride for about an hour today but I am impressed, honestly the first time I have ridden a bike that was set up correctly for me.
Many years ago a very wise NESC expert rider schooled me on an aftermarket exhaust.
"Many times you end up slower with a faster pipe" He meant more hp in many cases actually fatigues a rider and allows other riders to take advantage of a rider who is racing tired. Granted this was years ago racing 125cc 2 strokes, when you added a pipe the power became ballistic, but ONLY ballistic at above 11K rpm's. No doubt pipes today offer a far more broad power increase, but you understand my point...
There was a performance company back in the early 80's called PSI. They were famous for KILLER hp ported cylinders and pipe combos. The dumba$$ I was I bought a PSI setup for my already too fast , peaky 1984 KX125. After the mods my bike was so hard to keep on the pipe, after a few months I put the bike back to stock, added a 2 teeth larger rear sprocket instead (also upon the advice of the wise old expert), and sold the PSI stuff to another racer who claimed he was "so fast" after the PSI setup, I personally never saw any of his "additional" speed. I did however see him on his a$$ lowsided in many soft loomy corners ! LOL
