    NCT question

    Lads, anyone know if you can fail NCT for no back box, silencer?
    Cheers

    I'd say if its within the noise limits it might not be a big deal?

    Really depends on the tester.

    To save starting a new thread. My mx5 is a 1993, does it need a cat for NCT? Want to decat it but can’t be arsed swapping it in and out annually.

    Id say it does, my 99 s2000 wont pass without it. I forgot to put it back in one year, dude said it wouldnt pass as it originally had one.

    That might change when it hits 30, but i cant imagine it happening before then. After 40 its no longer tested afaik

    I think 93 is ok, if it's an import it won't matter, bottom of page 18.

    The turbo is muffling it enough.
