Thread: Passing inspection!

Ok my grand prix has an Overkill pcm and it has no cat. I asked Will to tune out the codes for the cat. But am still wondering if it will pass the obd2 scan for my inspection?

yes, It should

Depends on how my system monitors your state allows to show "not ready". With no cat, the Catalyst monitor will always show "not ready".

And that would be incorrect. With the code changed to no report, that monitor shows as ready.

So what do you guys do if the inspector decides to look under the car?

Then you run something like this.

Catalytic Converter

Or
3" Catalytic Converter High Flow Thunderbolt OBDII | eBay

or
3" Thunderbolt Catalytic Converter High Flow Stainless Steel | eBay

I've got one that looks like the second one.

Good news. I passed inspection!! :-D And I have a fake 3" stainless cat/pipe that looks like a cat lol :-P

They scan your exhaust and it passed with no cat?

Yeah I don't have a cat. The pcm is tuned to not report that there is no cat. And I passed :-D

but do they "look" for the cat to be there?

NJ just had cameras put in the floor and as you drive over it the tech can see the monitor, and you can see your whole exhaust.

before that they used mirrors on a stick.

Even if they did look it looks like I have a catalytic converter there anyways. I bought a fake 3 inch stainless steel cat online. Which is a 3 inch piece of stainless pipe that is shaped like a catalytic converter.

Delaware doesn't look, they do a sniff test.
