Is not the stock manifold a mani-cat on your 09? If so (I don't 'think' they changed from 05-07), why would you run two cats? (or for that matter, if your running a header for performance why would you negate the benefits by sticking a cat on the end of it?)

But! We digress. The question was where could seige123 locate a bung for his A/F meter on his stock mani-cat. A header is tempting, but regardless of what catalytic converter you stick on the end of it, it won't pass emissions if they do a cold start sniff test. Which around here they would if they saw an aftermarket header (and they will), or just fail it as it's not OEM. But, things are diff in various parts of the country so its really a local issue.

In NC the engine has to be at running temp to do the sniff test so the CAT would be heated , place the wide band o2 in the second hole and you will be fine

Tom

General group question. Is anyone aware of a location in the country where they actually DO a cold start sniff test?

You think the wideband will have sufficient exhaust flow? (Yes I am aware that the bung is somewhat imbedded deeper into the canister, but its only ~1/2").

I'll do the 2nd o2 from what tom said for now. I live in illinois and its illegal to remove the cat but I have gone to do my emmision testing and they do not check under the hood or sniff the tail pipe. They just do the obdII. So I think I would be fine as long as I do not get a failed signal on the o2 sensor readings, which from what Tom said, it should not be a problem if the rear o2 sensor is disabled (this I have to test out unless someone has done it already in illinois).
Also, Im just setting up for a turbo in the future and a header would be a waste of money for me unles I get another focus or I could sell it locally...

Okay, and?

You're suggesting that the stock SVT would fail an emissions test? That's hard to believe.

You are right on IL my buddy has a 2.3 swaped turbo focus which has a cut off after the down pipe and he passed emmsions in IL

I am emissions certified and In IL what they told me about people like us" that cheat the test" is that is to small of a percentage to worry about

So if ur in IL and the tune disables the rear O2 you'll be fine

Not as hard as believing you would inject an SVT into a Duratec discussion.

I have to admit that I have gotten ~same replies from some testers in STL. As long as you don't throw an OBDII code (which in MO goes straight to the state. Not sure about other states) you should be fine. So agree!

Down in Southern Illinois there is no emissions testing. My car has been in Illinois for latter 3 years now, and no problems at all.

As a matter of fact, My car has never been tested since I bought in 2004.

i would recommend putting the sensor BEFORE the CAt. I was told this buy a fellow SCT tech. and a AEM tech. reason is, installing after the cat will cause the reading to flux. you won't get a accurate reading. the flow of flume builds up in the cat and release a reading only a wack job can read.


when i had mine in my second o2, i had reading from 11 to 14..... and it should of really been around 11 to 12, 13 is getting close and 14 is past....


just my cent... but what do i know?
