High performance cats

That sounds like a good idea as I believe the exhaust pipe gets smaller after the cat but before the axleback. I'll bet that Magnaflow has already tested their exhaust on a Yaris and already knows that it passes emissions testing, or by law they would have to put a disclaimer on their product just like for any other non compliant "race only" accessory.

If you're not sure, I'd simply call them and ask.
