I'm pretty sure that the stock o2 sensors would not help. You need o2 simulators that would tell your ecu that it is running like it would with the cats in there. The stock ones on there would probably just give you a check engine light for sure.

Just to be sure, this wouldnt pass emmisons right?

The ones pictured take away all cats excpet for the b-pipe (cat part of a cat-back exhaust for our car :wink: )

Definitely wouldn't pass emmisions

That's 2 lies already. Don't get 'em if you know that some of the stuff they are saying is complete crap and other stuff can't be verified.
