So I've deduced Im probably not hitting emission requirements in Australia
(numbers/discussions have always been vague) Im guessing my tune has disabled the sensor error.
-What are the cell ratings on the stock headers cat?
-Would there be a 400 cell catted front pipe to meet requirements? Or is it necessary to have the cat in the header with the sensor?
Im in need of suggestions to go forward. I don't want to buy another header, but I am open to the idea if necessary.
