Basically:

USDM WRX: (05)
Twin tip exhaust
Smaller Hood Scoop
Smaller less flashy rims
Wagon model
No fog covers
No HIDs

USDM STi: (05)
Monstrous exhaust (Single Tip)
Large hoodscoop
Large rally style wing
17s Stock
HIDs
Fog lamp Covers
No Wagon Model
STi Emblem and Stickers

 

05 WRX has a single tip now. 04 and earlier had dual.


Also look inside the car, the STi has a blue/black interior while the WRX has a grey/black interior.

 

or just know your cars..... maybe not all, just subaru, study it, its life

 

Well ut actually correct im not from the us, im from the c/bean and i have a gc8 model STi from japan, but there a couple ppl here who buy the same GC8 model but they a just WRX and they put STi parts on and con buyers who are interested in purchasing, was just askin for a lil knowledge so i can tell some people what to look for if they lookin for an STi and not a WRX

 

The WRX looks has a smaller hood scoop, smaller wheels and a lower trunk spoiler. The STI looks like a blur.

 

do the carry the same size TMIC ??

 

I think the STi's is either bigger or water to water cooled as opposed to air to water cooled.

 

no. according to specs from soa--- the sti is 30 percent larger


aloha from the summit of *-^-Mauna Kea-^-*

 

so i take it only STi's come with the IC water spray system

 

That is Correct.

I'd say take a look at the huge golden brembo's!
