I just picked up this Test pipe for my ap1 from a local shop, When in there I was told that id require a CEL fix kit to stop the CEL when removing the cat pipe.
My question is what size orifice should I be using?
The smallest one should have the biggest chance to not throw a CEL so that's what I would use.
But I'm pretty sure you wont need one at all though, at least not if you have a pre 2006 car.

Will there be any difference in performance with each different orifice? Any greater chances of leaning out?
The second o2 sensor does not affect performance at all it is just there to verify the cat is doing its job. There is no chance of that sensor affecting fuel ratios.

This is my understanding. So just choose the smallest orifice to make the CEL least likely.
