    hi all,

    my friend has Audi S3 2.0 T FSI (8P) .we're planing to Chiping his car from Unitronic,changin box air intake with open air intake from neuspeed and changing exhaust sytem with kind of freelow exhaust system.

    so Here is the deal;

    As you all know S3 is deeply electronic.we're hesitating at replacing his cat. with freeflow exhaust.Nearby 2 cat. there 3 sensors.Can the chip companies (i'm thinkin about Unitronic chip) deactivate them from without giving the check engine-red light on my indicater after I took them out ...? And let me gain 15-20 horsepower from my exhaust system....

    thank you all...
