My 05 WRX was a stage 2 before I bought it. It has the catted d-p goin to a catless exhaust.
Now a buddy of mine told me that the CEL fix only works for 04 models. Is this true? If not, where and what CEL fix would you recommend?

depends on which cel you are getting

if its the one for the missing EGT bung in the aftermarket up-pipe, putting a 2.2kohm resistor in will take care of that cel.

if its the downpipe cel because there are no cats now, catless dp and mid pipe, there is a fix where you go buy some spark plug anti foulers from an auto part store. search for this mod for specific instructions

both of these mods will take care of either cels and no engine management(cobb, opensource) is needed
