So I'll get a CEL with the catless do even if its got the bung for the rear o2 sensor? And if so, would the accessport be able to keep it off?

Um ok. Doesn't answer the question though

You can use Accesstuner to turn off the CEL for no cat.

Also if you do not have one they make universal O2 extenders. I think 2JR and other brands sell one. It makes the o2 sensor sit further away from the stream therefore not triggering an out of range reading and triggering a CEL. I have one on my car but I havent driven over 400 miles to prove i dont get a CEL.(400 miles is usually when i have seen people report getting a CEL for no cat)

Also the Cobb OTS stage 3 tune will turn it off

Do people run the carless downpipe without the stage 3 tune?

I run a catless DP without the stage 3 tune. Instead I have a custom mountune tune as I havent upgraded my intercooler yet.

A tune will be required to run a catless dp.

Buy a catless DP and then get retuned. Simple as that, and will make the most of your new purchase.

I dont have a tune at all but I have all the parts (minus the intercooler since i havent mounted it yet) for a stage 3 tune LOL I am sure its not at top performance obviously but i havent purchased an accessport yet.

Why catless? Unless you're racing, why would you want a ton more pollution for a tiny increase in performance?

Less expensive (by almost half), a little more power, and the sound. People have many reasons.
