It is illegal, and you will also get a check engine light.

2nd set, not first.
Hey guys, I believe that tech was speaking of the 2nd set part of the downstreem pipes with the Cats on them. NOT the set closest to the headers. EPIQ makes a set of these with bung holes for the sensors to still work and not throw off the computers settings. They say it will still pass emitions. Plus it's an easy bolt-on job, so you can always reverse it if needed. Yes, it is illegal on all states that I know of. But if you pass emitions, how could they tell unless they were underneath your car. Check out these pipes at EPIQ and read the discription.

Those aren't the pre cats. Precats are the ones nearest to the engine, as you stated in the first post.

Yes we know. But the tech that he was talking to most likely got it wrong. He got his CATs all mixed up.

blue ,
I just repeated what the guy told me don't kill the messenger ...Like i said i wasn't sure really what he was talking about at first. He told me i really don't need to do headers to remove the cats and that i would gain hp. I am sorry if he was wrong but that is what he told me.

Unless I am mistaken, you are crapping up the air when you remove the cats.
Seems like that might be of concern.

Yes, true. But do we really need 2(pair) sets? Our cars have 4 Cats. on them total. Makes no sence to me. Why not just 2? I've never heard of any other car having this many.
