Difference bw WRX and STi exhaust?
Is there a difference between the stock '04-'05 STi and '02-'05 WRX exhausts, turboback (other than the muffler)? TIA.

I have an 05 and I believe the tip on the STi exhaust is larger. I'm not sure about the pipes though.

Piping is the same. The flange sits at slightly different angle but it will still fit fine.

The diameter of the piping is a bit larger, of course.
