It all depends on what catts the manufacture is using. For example: cP-e went through like multiple catts suppliers till they got it right.
Also, it has been suggested that certain tunes ride the knock sensor which is bad for high flow catts causing them to go bad quickly.
We will know soon enough, I will be doing a voluntary test this coming September
