Default Emmissions Limits

Hi,

I am wondering how far I can go with mods without failing CT emissions testing. I would like to do B&B exhaust, headers of some kind (suggestions please), a cold air intake (again, suggestions on best power gains), and I also heard that upgrading the throttle body can be a big HP gain.

If CT emissions standards are like California's then this is what you can and cannot do.

Supercharger (Passes Smog no Problem and will have a EO #)
Exhaust/ Catback (Passes Smog no Problem)
Long Tube Headers w/ Cats (MAY pass sniffer but will not pass visual)
Cold Air Intake (Will pass smog as long as the CEL is not on. Some CAI have carb #s such as K&N and Callaway)
Cams (MILD cam (220-223) will pass smog sniffer)
Ported Intaked (Will pass smog)
Ported throttle body (Will Pass smog)
AFR Heads (Will pass smog and have EO#)
