    My guess is that the guts from the catalytic converter were removed for increased flow, or it was simply deleted. It could probably be made legal with the increased performance, but the original owner didn't want to pay for it. If their only concern was trying to wrench more HP out of it, what might the original owner put that engine through?

    I wish technology solved people issues. It seems to just reveal them.

    From the description, one might expect the dealer knows it has gutted cats and can't just bolt on the OE exhaust and take a pass.

    Gutted or not, AFAIK, aircare just needs to see the cats are there and have it pass OBD/sniff tests. There's lots of cars running around with gutted cats that easily pass emissions.
    My Feedback
    Credit TFOGGER : Liberals only want things to be "fair and just" if it benefits them.
    Credit Zundfolge: The left only supports two "rights"; Buggery and Infanticide.
    Credit roberth: List of things Government does best; 1. Steal your money 2. Steal your time 3. Waste the money they stole from you. 4. Waste your time making you ask permission for things you have a natural right to own. "Anyone that thinks the communists won't turn off your power for being on COAR15 is a fucking moron."

    Except some newer cars have more than one O2 sensor and will throw a code due to decreased cat efficiency. (VAG)
    Thats why I say to pull the codes and see what pops.

    Right. But there is a cost to it. I just want to bring it up so he is aware that it has to bealt with, if applicable.
