And if both cats are swapped for high flow, will the sniffer be satisfied? I only swapped one cat for a Cobb high flow on my WRX and failed miserably. Pissed me off.

I only said EL headers because those are the only headers so far I have found that have a cat, I don't think the EGT temps would have a difference because they all collect at one point so. I do believe with a tune and two cats being swapped the sniffer will be o.k. but only in the case of the FA20.
