When I swapped in a catted dp, my stock dp had 2 cats. Any reason for that, especially for a CEL just cause one recent highflow cat? Maybe programmed to have 2 cats. lol

And in case everyone say a tune will fix it...I get it :)

If you put in a high-flow cat, it is throwing a code because of that, and only a tune will make that go away.

A tune WILL fix it.

Also; the two cats are there are emissions purposes...not that they were needed really.

Yeah right? Some Balts come stock with one some with 2 cats. Mine wasn't even a Cali car.

My 2008 2.2 had two cats and when I went catless I put a spark plug non-fouler ,the longer size, on the o2 bung and barely ever got a code. But then I got tuned and tuned out the code. The non fouler was rough to fit with the lack of room down there though.

It's an old school trick to space the o2 out of the way of the exhaust stream.

It's common on plenty of platforms so it doesn't trip the CEL.

Even after installing the spark plug trick, CEL would sneak in. Nothing like a battery re-learn fix to handle it, til I get her tuned of course.
