Can I do catless DP's in CT?

I am not sure if CT has really strict emissions regulations.. I am thinking about Bastuck quads and possibly catless DP's... does anyone have this setup in CT?? any problems?

do they use a sniffer there for emissions testing? Most places that I know of use an OBDII scanner to check for codes....no codes and your ok. That means you need an O2 simulator to make the cars computer think you still have your primary cats. I have not had any problems with mine here in MD.

since you have an 08 do you have the 29.2 software? is your build date 3/08? check the driver door stickers if you dont know.

if it is then id suggest the tune or the DP's but not both.
