Header suggestions?

[thomasterrible]

Stock cats will not fit a header setup. High flow cats are positioned in the Y-pipe downstream from the collectors. I run Kooks high flow cats on our car - wanted to keep at least something on the car street legal.

Ok thanks much. This state does not look for physical changes but just sees if there are any codes present.
I am wondering if it is possible to get it to pass with just the resonators or if the states computer would figure it out when they hook it
up at the emissions testing station?
If I can't sneak past that then I will just go with the high flow cats. It would be pretty much my only choice so that doesn't take too much thought.

I will check out the full system and check on installation. That is another part I will be finding out about, how much labor is involved (hours) and if there is anything that is a fitment issue or things like the O2 sensor positioning mentioned although I think that particular one won't be an issue.

You can get the computer retuned for the exhaust setup. It will delete the emissions for the cats and you will never have to worry about emissions again..well for at least the cats not being in the system. You can get a mail order tune from "tuned by frost". He's really good and well known on this site. While you're at it, you should also remove the EGR and AIR systems from the car. It really cleans up the engine bay and takes away a few pounds of unnecessary weight. Less weight = quicker car!!
