Catless headers and inspections

[machosauce]

Just wondering what people do around the DFW area when it comes to emissions inspections when going catless? It seems like way to much of a pain to put the stockers back on. I was thinking some of the headers may have cats that can be swapped to free flow sections when not getting inspected. Just trying to see the best route to go and I never had to deal with emissions inspections before. Thanks.

So I have Texas speed headers catless basically it’s the cats pipe but hollowed out so it looks like you have cats

Yeah I was looking at those headers, seem like a great deal. How have the inspections been with those on there? They say anything to you when you had it inspected?

No issues most shops do I visualized check on newer cars and don’t bother hooking it up to the emissions machine cause it should pass

Nice, I believe that's the route I'm gonna take. Thanks.

I took mine to a big name lube shop and they didn't care, but I have turbos lol. They actually didn't charge me either!

I was wondering if O2 sensor extensions would work with catless headers to not throw a CEL.

That goes away with a tune they will turn it off

That won't work in my county. They plug into the computer to verify all systems are ready. With it turned off they will fail the inspection even if there is no CEL. That's why I was hoping someone can comment if the O2 sensor extenders will work.

Hmmm I figured it was just reprogrammed so if looked at it looks normal

Yeah that's what I was trying to figure out as well. When my wifes Mini Cooper was done they did the plug in deal also. You had to drive around for so many hours with it plugged in. Maybe each county is different because I think I've seen some parts of TX that don't even have inspections. May have to move to one of those areas lol.

A tuner can completely disable certain monitors.

And the inspection computer will know that and fail me. I've already tried it.

I'm wondering the same thing in the Houston/Woodlands area. I have catted headers with a Lund tune. Since Lund turns of rear O2, its going to fail OBD2 check. So how are others getting around this cuz TONS of cars have headers....
