Nice job! So, what is the equation for finding the rpm to tune the collector location for? I have read that collecting further away tunes for higher rpm, which is the opposite for tuning a restriction point (ie. tuned pipes on two stroke engines). I have also heard that the RB collected header is tuned for street use (midrange).

with the collector pipe. It is oval into the 3" inlet for the SPINTECH muffler. Yep... I hear ya'll scraming:"ITS TOO BIG!!!!!". I know I'm experimenting. IF it sux, the components will work on the turboII.
