i know a e303 is a CA smog legal cam, but will it pass with only 2 cats instead of 4? i am asking because i want to run long tube headers with 2 high flow cats n an e303 cam. i can get past visual but it needs to pass out the tail pipes. any one know??????

The answer is yes in the current configuration. What type of heads are you running? What other changes have been made to the motor? The cam, cats, & headers will not fail you on an emissions test. Do a tune up, run premium gas and you will be good.
