Can a mod mustang still pass smog test

Mustang2005 · 08-14-2008

I'm on orders to go to Washington State. I just found out there is a smog test. I'm a little worried, I have an 05 GT with a High flow intake, motion delete plates, UDP's, throttle body spacer, and of course an SCT programer running 91 octane. Does anyone know, should this pass the smog test for tags.

my car passes the smog test. i think yours should be fine. The only thing you have to have in WA is emissions equipment like cats. I have seen guys there driving around 800hp turbo cars as a DD

Well, there you have it. I wish CA had regulations like that.

tell them you want to do a test run...

see what the levels are....

In california it needs CARB # for any mods.

If you have cats and have the rear O2s turned on you should be fine. Thats what I have to do. I have a seperate emission tune just for that. You do need to drive the car at least 50+ miles to reset the computer..
