hey 03 what i mean is that from what i heard from the ppl who install the RRM header it gets rid of the 1st Cat Converter. Which is why it gives ppl so much problems with the 02 sensor but since its gone what fills in the space since its in. In my mind i keep thinking that the header covers the area from exhaust manifold to where the 1st Cat begins. sorry if i didnt clarify b4

Look at the parts and at the car.
RRM header does remove the 1st cat, which is inside the stock header.
The stock downpipe does bolt up to the RRM header.
The 2nd cat is the one back under the car (directly under the seats).
It is possible to avoid CEL with the RRM header. I know, I've done it.
Know what you're talking about before you preach!

RRM make an exhaust manifold(header) without a downpipe. Their header used to cause a CEL light, now they have a CEL eliminator or something like that. If for example you would leave the stock header on and buy just a downpipe (from a muffler shop, secret info, or somewhere else) it would not cause CEL.
I'm not trying to be a jerk but come on, you have their non-ic kit and you should know all of that.
PM me or BlackSheepDj for the secret info.
