Thank's.
So I actually ordered 1 621 T and 1 621 P.
The T is going in my 8T 2.0 and the P in my Uncles 8T 2.0.
He is going to use a JP 2 pipe and i'm going to use the Radical pipe and header. I'm not sure how many spacers to use on the pipe. We are both going to run Dave's plugs.
It will be interesting testing to see how each motor runs and with each pipe combo.
