Also please feel free to share any knowledge you have on how the n20, AWE exhaust and JB4 all interact together if you have this combo.

Thank you.
Swapping to the AWE midpipe is not a suitable substitute for a downpipe on an N20. The reason you get a catless downpipe is to remove the catalytic converter, which is very restrictive. The only way to do that is by swapping to a catless or high flow catted downpipe. The mid pipe is not restrictive at all on the N20.
