Really hoping for some help here.

Akrapovic makes a 100 Cell Sport Cat (L-PO997TFLS-100) and a 200 Cell Sport Cat (L-PO/SS/2H) for the 991 Turbo (S).

Has anyone had success with either of these Cats - with regard to not tripping a CEL??

I don’t want to ‘tune out’ the Secondary O2 Sensor - and would greatly appreciate some guidance from folks with first-hand experience - good or bad.

Thank you - be well…

 

Hi Erik, I ran Fabspeed 200 cell sport cats on my 991.2 turbo and they did not trigger any CEL on the stock ECU. I would say the Akrapovic 200 cell is a safe bet. If it does trigger the CEL, you can use O2 sensor extenders instead of tuning the car.
Side note, I am posting my fabspeed cats for sale this weekend if you're interested...

 

Herane, thank you for the feedback. I'm guessing I'll be fine with the 200 Cell Cats - just hoping to hear from anyone with first-hand experience.

O2 Extenders are definitely an option - be well...

 

Another option is to do the following:
- Buy an OBDLink LX Bluetooth Reader that plugs into your ECU (inside drivers side door)
- Download the aOBDLink app on your phone. This will allow you to see engine performance (IAT, AFR, etc,)
- Download an app "Torque (Life)" on your phone which is another ODB reader that will allow you to read and clear codes

911TurboTim, indeed. But the Code will almost certainly come back after clearing.

Thank you for your input - be well...
