long tubes

[the codes]

so I know long tubes delete the cats and that's illegal in texas but if I know a guy who will pass me...?

I know with the cat delete codes get thrown, isn't there a fix for this? I was trying to remember it the other day but just can't remember.

I don't think there is a way around it because you won't pass a visual inspection. Better move to a stat that don't care like Iowa

haha right? of all the places you'd think texas would care less about smog haha

Farming states seem to care less because of tractors etc.

I've never had a truck visually inspected. As long as its not throwing an CELs and everything is stated as "ready" they don't care.

When I lived in new York I had to pass the computer inspection and a visual inspection.

 

[BlackedOutHemi]

Well, if he's in Texas, like me, then he shouldn't get a visual.

im not as worried about the visual as I am the codes from not having the cat. I think there's a module that fixes it or something like that

There a defouler that I use because my cats don't filter the exhaust enough.

hmm yeah that sounds like what I need. I apparently have a short in my wiring that runs from the computer to the o2 sensor harness. guess I'll have to get that figured out before trying to get rid of the cat. *sigh*

No emissions check in Texas.

I used spark plug defoulers on my 05 and they worked great, and I had racing cats installed.

No emissions check in Texas.

maybe its based off county...in Houston I kept failing inspection because of my 02 sensors?

Long tube headers just mean you have to move cat. You could still use one if you wanted and the sensor. This means you need to put the cat as close to headers as you can, and use header wrap or ceramic header coating to keep heat in pipes.
But in Missouri it dose go by county because I live in Franklin with emmissions and just 2 miles away in Warren they only have safty.

[DOAX]

and on the topic of headers

at what point do the stock manifolds on the 5.2 and 5.9 actully become restrictive

haha like that answer. considering the extra performance doesn't make you have more of a lead foot, what about mpg?

If your O2 sensors are not ready, or are malfunctioning, you will fail the test. That is through the OBDII port though. Which is computer related only. If you have an emissions check, they toss a tester on your tailpipe and check it like that, and then visually inspect it.
