What’s up, all! I’m a newcomer to the forum and have been on here often for research, knowledge soak, and general love for the wrx since high school (2009). I wasn’t raised turning a wrench or around cars, but when I first saw the 2008 wrx, I was in love! Then started my appreciation for the...

So I have this 2004 Subaru wrx 4EAT I just got a custom catback installed and I’m going to put the Cobb intake tomorrow. Do I go to stage 1+ when I put that Cobb intake? I also have the Cobb access port v3

I had a j pipe installed Friday and was told the Cobb 2+ plus v400 would work. However it does not as Cobb updated the tune to work only with the new gesi catted j pipes coming out. So right now I’m stuck with a cel (P0420). And I have no way to get the v361 version as Cobb discontinued it and...
