Thinking to start a helpful thread on emissions here, because I know I had problems with them at first. I'm thinking more of a research thread than anything, because I know people are always having issues with this. I have looked all over the TX DMV site, and am about to start calling around, but this is all I have found so far:

http://www.dmv.org/tx-texas/smog-check.php

It's only listen certain counties as smog-checkable. I live in Bell County, one of the ones NOT listed.. would it be safe to assume that I'd be okay with an offroad pipe? So, I called around to the shops about here. I advise you to do this in your state. Currently, non-smogcheck counties Texas require only three things, via visible inspection ONLY:

1) Catalytic Converters
2) Mufflers
3) Pipes run all the way to the rear.

After that, you're all good!

 

from what i understand, most won't get under the car at all...if you have a working horn, lights and blinkers, and the car drove there it'll probably pass. that is not everywhere, but it seems like the general attitude of emissions control is a lot more lax when the government isnt breathing down your neck like they do in testing counties.


btw, every state has their own website and i would trust their info a lot more than a third party site like the one you listed (though all of that info is correct, who's to say they are going to update it as often as necessary)

 

It was actually one that I did pull off the DPS website, oddly enough.
