After seeing what seems to be a higher percentage of AP2 owners (myself included) that received cel's with the Berk pipe, I have decided to go ahead and order the Megan pipe from the group buy and give it a try. I am asking AP2 owners to respond and let me know if you got a CEL after using the 42002 anti-foulers with the Megan TP. Thanks for your help. Posting any experiences would be great as well.
