WRX EJ255 VF52 CAN (09 – 13)

Option 2: Exhaust with Ezy-FLASH Pro

Adds approx 35kW / 120Nm (21%) peak power at the wheels.
We recommend the Invidia Q300 Turbo Back System. They are well made, fit nicely and have a weighty note without being too loud.

WRX EJ255 TD04 Drive By Wire / CAN (06 – 09)

Option 1: Ezy-FLASH Pro

Adds approx 19kW / 70Nm (14%) peak power at the wheels. Peak torque is made 500rpm earlier.

Option 2: Exhaust with Ezy-FLASH Pro

Adds approx 31kW / 100Nm (23%) peak power at the wheels.
We recommend the Invidia Q300 Turbo Back System. They are well made, fit nicely and have a weighty note without being too loud.

Option 3: Turbo, Exhaust and Ezy-FLASH Pro

Adds approx 65kW / 180Nm (50%) peak power at the wheels. Torque and Power is stronger higher in the rev range.
We generally recommend the VF34. It’s a proven turbo choice that has a good street power band. With this level of modification (and age of the car), it’s a good idea to upgrade the fuel pump at the same time. A CAI and Intercooler adds to the boost consistency at this point.
