To not get a CEL you would need to route your wiring to the section 1 cats. The North American section 1 cats are shorties so they may not be good enough to avoid a CEL. Getting a pair of euro cats would be ideal.

Ok thanks. So let me ask you, I purchased a rogue S-Pipe from Schmoupe which gets rid of the unmonitored cats. If I were to get these headers PLUS the installed S-pipe on my car, I'd have NO cats at that point correct?

Honestly, I'd be happier with just the stock headers and the S-pipe and call it a day if that's the case. Thanks for your help everyone, and I'm sorry to threadjack like this.
