I've heard the Apex'i N1 in person and it sounded pretty good. I didn't ask if the owner changed the frontpipe or downpipe though. It's high on my list.
However...I think the resonator delete seems the way to go as well as the frontpipe change with the valve open.

Updated the chart and use the standard PRL intake kit instead of the CF version.
