I agree. While it is excellent for Che to provide product for testing, and I commend him on that, I'm not sure what good 4 02 bungs are going to do when you're running without cats. I would think, either the high flow cats (like FabSpeed uses) with a Lamda before and after, or if running catless, a Lamda before and an "02 simulator" after to make the ECU think things are happy. Simply plugging in an 02 in a non catted header is sure to piss off the ECU me thinks....
