Rpw headers 41mm or 44mm?

Hi, i have a 2.4L 4g69 in my lancer and i’m having a hard time deciding between the two rpw header sizes

I plan to have either a stage 1 or 2 cam put into the engine and will be having the ecu reflashed with a stage 1 tune by off the clock motorsports,
So i’m not sure what header size will benefit my lancer more
