Yup catless up pipe...

Only your STI gets a differnt motor... Drivetrain is the same...

We get the subaru four pots standard, as well as the nice bucket seats... Alloy Hood... 182 Kw (250hp)... 17" alloys... alloy front arms (sedan only)... HID lights...

I thought yours had been raised also???

Down here the NZDM and ADM are both 9.0:1 just like JDM and both our domestic market WRXs are only rated at 160kw... (220hpish) compared to 182kw (250hp) JDM

They detune the ecus cause of our petrol... Less aggressive fuel map, compared with the JDM

Thats not a bad thing... The latest REXs are a lttle tough to tune for the reason that the compression causes early det, unless you spend dollars on fuelpump, injectors, UTEK etc... whereas my oldschool 8.0:1 just loves a tickle everynow and again...

It has seen 1.51 bar on original STI standard motor... Thats on Race gas mind you, but still didnt miss a beat!

Cant say the same for CRAPPY JEs!!!!! couldnt even handle 1 bar for 1500miles! Yup im bitter!:D Dont buy them EVAR!!!!!!!!!!!!!
