Have you put the non-foulers on there? If not get two and do that...

But that still might not fix your issues. I have a MY06 and throw a CEL with my Test pipe and non-foulers...

Its just because MY06+ have a more sensitive ECU / 02 sensor.

get non foulers...use them both with a screen/mesh in between the foulers and you shouldnt have a problem. sometimes foulers will still give you a cel. but with the mesh it wont.

I've been lagging on this since cel doesn't bother me much but I'm just going to add a resistor into the signal wire of the 02 lets see if that tricks the ecu. I'll try it and report back.
