    Hi guys, right after getting my car running just how I wanted, the exhaust falls apart. It's come apart at the joint between the down pipe and the centre. Now I'm thinking maybe go for a straight through?! can I remove the Cat and oxy sensor or will that confuse the ECU? what are my options?

    Advise is much appreciated!

    Not sure how that will work as my one of the 2 oxy sensors failed on my Cat and every now and then the car would stall now its been changed it holds the revs better at stand still as well.

    you need the primary O2 sensor, control idle fueling (closed loop)

    the 2nd one just measures the CAT and sees if its still working for new legistlation.

    we have a new gadget that replicates the correct signal so the ecu thinks the cats working fine.
