N/A opinions needed
i plan on upgrading my car in the form of a header, and new exaust. after i install the header, will i need to install a set of bigger injectors/fuel pump, and something like an AVC-R or super AVC-R?

Bigger injectors + fuel pump wont help an N/A car. The S-AFC (IE fuel ratio control) is what you mean, and it could help to lean out the car more if its running rich rith the new exhaust, but its rather expensive and wont do anything much for power. Plus, alot of folks complain that their newer model OBD-II scoobs tend to have ECU's that learn around the S-AFC making it useless... It does work on older models well, especially for turbo kits.
