Yo, I just got my car yesterday and I was just wondering if I could put an exhaust made for the 02 WRX on my 04' 2.5 RS. If someone could help me out on this I would appreciate it. Thanks

You can but you have to cut one of the flanges off and rotate it and weld it back on. I've never tried it myself but everyone says that works.

Sorry i meant I have an 02' 2.5 RS

The same still applies though.

Yo, the '02 and the '04 are close enough to the exact same engine that most of the same instructions apply, and if they don't they can be modified slightly to apply.
