SMOG Test

[cali yaris]

I would call first and tell them what's on the car, and ask if they'll test it. Most stations I know of want the money and will ignore visual mods.

There are no CARB legal parts for the Yaris.

Maybe, but an axle-back muffler does not change emissions, so it shouldn't count. I've never heard of a smog station rejecting a car with stock header and the cats intact. Same with a pulley or any other mod that does not affect emissions. Doesn't mean it hasn't happened though!
