Top gear for the numbers above. I was interested in midrange power. Rpm right around 4k, little below at bottom and a little above at top with the better systems.
On some of the tests I also did a 3rd gear run. I did not do that for all of the systems.
For those that I did the higher rpm test in 3rd, the skinny separate pipes and open peashooters still came out on top.
