    Questions about my Hooker LTs

    Curious how two headers connect into one. Do they weld to the cat or do they bolt onto the cat? Never installed headers on anything with more than 4 cylinders.

    the headers will come down off the motor then end. you can either get a catted ypipe or off road one. it connects the two headers together with a smooth flowing junction and ends where the intermediate pipe starts(where a catback or stock exhaust begins).

    yes you can hook it up to the stock exhaust. the ypipe should end where the stock one did.

    some also run true duals, one pipe for each side, usually with a connecting pipe at some point... something else to think about

    if your gonna keep your rear o2s your going to need cats... that or your other options are to get them tuned or let them read ambient air...

    you have 4 o2 sensors on your vehicle.... the front two screw into usually the collector of the header and sense the air/fuel mixture of unburnt gasses

    the rear o2 sensors sense how well your catalytic converters work

    that being said, the front two are absolutely necesary, an will alot of times need an extension on the wiring harness....

    the rears can be deleted, this if for if you are going to be going without catalytic converters, if you delete your cats and still run rear o2's you will throw engine codes possibly putting your car into limp mode.... to delete them you can either get a tuner to erase their reading, or get simulators that go on the end of the harness and do just that, simulate that the o2 is working great... another option that will also work is to just zip tie them up so they aren't dragging yet are reading ambient air that is "cleaner" than the air the front o2s are reading...

    well you may throw a code by letting them dangle somewhere but it will not go into limp mode, to do it without throwing a code, gotta be simulators or tuned out

    It is no longer legal to sell simulators in the US... Get a tune for a permanent fix, and gain a few RWHP while you are at it.

    You may find sims on ebay, but a tune is a better way to go.
