    You can sorta see the second O2 sensor looking under the hood.

    It would suck for the OP if the smog guy finds his cat and he's then forced to buy the expensive CARB cat as well.



    Were they CARB compliant ??
    Yeah they did.

    Yes, they were. I had to make sure since I live in CA.

    There's two reasons to install the non-foulers.
    The first reason is because you installed headers and they don't have a pre-cat. The non-foulers prevent the P0421 Warm-up catalyst system efficiency below threshold.

    The second reason to do the non-foulers is when your pre-cat deteriorates, it prevents the same code.

    If stormkyori had headers when he first went for the smog test, they would have noticed as soon as they popped the hood then on further inspection they would have noticed the non-foulers.

    The non-foulers kinda stick out and attract attention.

    Then you fail your test and are told you need to buy CARB compliant cats. And,.. I'm pretty sure they would record your licence plate # and Vin # so you can't just throw on any cats and hope to go to a different smog testing place and hope to pass... They will have you on record and specifically look for CARB compliant components.

    Natey didn't attract any suspicion when they looked under his hood so they didn't bother looking under his car.

    My point being,... There is a chance the smog dudes will look under your car, then you'll still have to buy and install the CARB compliant cats after already spending the time and money on regular cats.

    So it's somewhat of a potentially expensive gamble.

    Personally, I think you should try the regular cat... It sounds like you have a really good chance of passing.

    And remember,.. You're not wrecking the earth using regular cats... Even if you have no pre-cat, the main cat will cleanup everything. (except for the first few minutes when your car is cold).

    You could just go for a road trip across state lines and do some shopping.

    I'm in TX, have header with non-foulers & running a magnaflow hi-flow cat. No codes and have never had any issue getting inspected. They do gather people around and point and look and then they come take my $3 off coupon and hand me my pass paperwork I need to go get the registration. Not that this has anything much to do with passing inspection in other states........
