I'm in Cali and I went with the supermaxx system. New 05, so smong won't be for until 2009.

"Vehicles four model-years old and newer are not required to begin their biennial (every other year) Smog Check inspection cycle until they are five years old. For example, a 2003 model-year vehicle purchased new would not need to have a Smog Check until the year 2007. However, these vehicles must have a Smog Check inspection if they are sold or initially registered in California during that time."

I'm not too lazy, so when they time comes around, if I have to, I'll slap the stock exhaust back on.

 

Does Cali do testing on every cali registered vehicle, or do they just do testing in big cities?

 

Bigger citys. Like San Diego for example....if you live in a city like 50-60 miles east, where the population is a few thousand, they don't enforce you to smog, YET, your car must run all the proper equipment.

If you get pulled over and the cop notices you're not running cats, big ticket.
