Default What are the differences between these? +exhaust

Apexi V-AFC2 and EMS? Arent they pretty similar? Also, when I had my exhaust made, I noticed our stock exhaust had like 3 big resonators, one behind the cat, and 2 before each dual exhaust. Now were those important to have for a "backpressure" issue? Or am I still fine having one straight shot pipe with no resonators at all?

VAFC is like EMS in that it can tune fuel and set your VTEC engagement.

EMS is nothing like the VAFC, however. It completely controls every aspect of your car; it is a replacement ECU and is 100% tuneable.
