Does the TBE fry any O2 sensors? or does the map actually recalibrate the sensor to read correctly?? Ive seen some people getting this codes thats why im wondering...

I wanna make my WRx Stage 2 but not if im going to be dealing with stupid codes and fried O2 sensors, and other miscellaneous bull...

thanks for the input...

You need to run some sort of engine management (Cobb AP, or an open source equivalent) to eliminate the CEL's that go with going to a catless DP.

As to "frying the sensor"; I dunno. I've had two WRX's with Stage 2 and beyond, and have never had a problem.

I just put on a Cobb TBE and went to stage 2 on Tuesday and everything has worked fine including the 02 sensor.

Sorry I forgot to mention I was getting the AP with a stage 2 map and the downpipe... I already have a SPT Intake and Exhaust... I guess as long as the stage2 map takes care of reprogramming the O2 sensors I should be okay... Do you know how much boost a stock 07WRX pushes?? and Running cobb Stage2??

Once you get the AP installed it will remove any codes that the o2 sensors may throw, you'll have nothing to worry about. Enjoy.

Even if your TB exhaust is catless the AP will make you pass emissions. :thumbup:
If it's only an OBDII port check - you will fail a visual/sniffer test ;)

I have a catless tbe, If cobb will eliminate o2 cel's why did the prevs owner of my car place a i believe its a resistor on the EGT sensor thing under the hood, or am i talking about 2 different things here?

Any thoughts?

you may want to check compatibility w/ your SPT intake. I'm not sure that your SPT intake is compatible with the OTS stage 2 map. I think it may not be

SPT/Cobb are both compatible, and I believe K&N is as well
