So I need to have my GTA smog tested in the state of Nevada this week. The exhaust is totally stock from the factory, but I do have a hypertech thermomaster chip, TB coolant bypass, and a K&N cone filter in place of the stock air canister. Will any of this effect my ability to pass smog? Thanks!

 

I was going to ask too, how much power those little mods gave me. I was thinking maybe 5-10HP? I know not much.

 

The Hypertech is probably a waste of time, and may have an effect on the emissions test. I would just run the stock chip instead. As for the other stuff, do they do a visual or just sniff the tailpipe? They may fail the air filter if they do a visual and depending on the rules there.
