    Is it possible to install a cat back system on a civic ex that has an
    automatic transmission?

    I helped a friend with a header/catback install on a 2k4 1.7liter
    civic ex automatic. the kit we got from ebay, then also ordered the
    header, and a downpipe that connected the header to the catback
    system. the catback was specifically for the LX civic, but it bolted
    up fine. ps- the car now has no cat, and the exhaust is fairly loud,
    but not highpitched. total cost was around $350-400

    So with no Cat, does that affect the ECU at
    all? obviously the o2 sensor after the cat
    would be getting much higher oxygen readings.
    or do you bypass that sensor by looping it?

    just curious, also isn't it illegal to run with
    no cat?

    Why are you running with no cat?
