Default Need suggestions


Hi, I own a MY02 BE5 Legacy. I plan to do power mods in the future and would like some more definitive suggestions.

I have read countless forum topics about getting power from the NA EJ25 so by no means am I naive when asking all this.

I am going to be putting in a RalliTEK transmission mount bush and in the process my FSM says I remove my headers, center pipe and muffler. I figured while doing this I should put UEL headers on. After some good research on the comparison of EL vs UEL headers on NA, I have concluded that it's best to stick with my stock EL ones, as I never wanted to go for UEL for the boxer rumble.

Enough debriefing, now it's time to list the intended mods:
LW crank and alternator pulleys
WRX intake manifold (for larger bore, if it bolts on)
larger throttle body (70mm perhaps)
High flow cats (no cat delete, I want it all legal for DD)
2.5" CBE into Magnaflow muffler
Delta cam 1500 cam grind
Piggyback/ECU tune
Crane Cams XR3000 ignition module
high flowed injectors or WRX injectors
fuel pump

My main question is should I go 2.5" or 2.25" exhaust piping?

I'm in Australia so I don't have access to Stromung, TWE, Bruellen or COBB exhausts.

Thanks for reading.
