I have to ask before spending any money:

I'm getting ready to get this Catback for my ride, and wondering if this one would fit the 2003 WRX, since it says "STI" but there is no STI in 2003. Anyone know?

Looks like Vivid Racing has both one for STI's (also '03-'05) and one for WRX's ('02-'05). If you have a WRX, you probably should try and get the one designed for the WRX.

However, I have not seen a catback comparison of a Stock STI vs. Stock WRX from underneath the car, so I really couldn't tell you for sure if there is much of any difference in the path of the exhaust underneath the car which could cause you problems with fitment. Maybe someone can chime in on that as if there is no difference underneath in the path, then you would probably be fine getting either exhaust.

You could ask Greddy as well to see if there is a specific difference.

 

Thanks so much for the info...I'll check it out! :-)
