I looked at the spacer issue some time ago. Got someone to post consecutive dyno runs w/o and with. As suspected gained a few hp way up top but lost more down low. Same sort of things one expects by opening up the exhaust. I spend most of my time in less than WOT scenarios so probably won't go with the spacers. I suspect Rob's datapoint will reveal the same.

Huge amount of work! Well done.
