Will you post a video of the sound of your Gen2 with catted DP into stock exhaust? Did you experience any codes? If yes did a tune resolve?

Kooks down pipe

With the kooks Catted down pipe I've ran two codes and am looking for a option to remove these engine light codes other then 5 star tune removing them. I've seen people talk about extenders but haven't seen any part name or part numbers for people to use. Any info would be great.
Ps I have kooks DP and 5 star tune but if I had no tune I would have a code showing. Thinking of running other tunes and would like another option to remove codes.

Have you talked to Kooks? I thought they guaranteed no CEL?

I have the same issue tried o2 extenders and still codes any ideas before i rip the down pipes off like i did with Corsa that would make me almost 4K in a hole .

That's crazy I pulled my S type off absolutely hated it and went with just the down pipe. 5 star tune has cleared mine but with them it would be on 24/7. Someone somewhere must have a fix for this

This was same thing the first generation ecoboost group found. Funny nobody researched this stuff.

Can down pipes cause engine miss fire message ?

No. You will find ecoboost misfires as a very common occurrence. Not sure if that is something to be afraid of or not yet.
