Default Stage 2 Setup, impressions? CEL?

Hello,

I have an 07 WRX TR and I'm ready to go to Stage II!

Cobb AP v2
ERZ Bellmouth Catless DP
STI TMIC, with y Pipe and 90* Hose.
Blitz Nur Spec R CBE (already on)
Injen Intake <-(not by choice, came on the car... ugh)

I got a couple Q's. I know I should NOT to Run the OTS Maps with an Intake, so I'm going to get and E-Tune for it before doing anything.

Q: Since by CBE tapers to 2.5in at the DP and the ERZ DP is 3in all the way do I need to get a special Gasket? Or how will they fit?

Q: Is there anything else I need to do or look into? I have read things about boost issues and such. Or just bolt up my DP and IC, Apply the correct map and go?

Q: I live in NJ, and will be able to run the 93 oct Map. But since I am going catless will I have CEL issues? Any way around this?

Thanks, I did search but wasn't able to fine much conclusive information.

I can only help with two of your questions.

1. You should'nt need a special gasket for the catback. I had a Greddy Evo 2 that tapered and I was able to use the standard 3" gasket.

2. The Accessport will turn off the CEL's for the catless downpipe. So no worries there.

Hope that helps.

Hey, thanks for the incite!

Is it bad that the AP will turn off the lights? lol

Also, for anyone Catless, what do you do with the 02 sensor? Just unplug it? or will it still plug into the DP?

Your downpipe should have a bung for that o2 sensor.
