    Question I'm Confused - DeCat

    Hey folks, i know this might sound ridiculous, in fact, it is ridiculous, but what does a DeCat consist of? Is it just a pipe that replaces the exisiting Cat? I'm thinking about doing it because my cat is broke so i might aswell DeCat it. If it's just a pipe, where would i attain one? Thank you for any help you have to offer.

    You can get customs ones made up at Powerflow dealers etc or u can look on websites like Demon-Tweeks as some manufacturers produce them.

    However AFAIK u cant fully decat an Astra mk4 cos the emisions light comes on and the car goes into limp home mode.

    Also, a decat is illegal and will fail an MOT or a roadside check.

    My car was fully decatted.

    The light didn't come on and the guy who fitted it explained what he done to the lambda sensor to ensure it did not affect the ECU but i cant remember exactly what he said. I got it done at a custom exhaust place in Glasgow for £70 iirc.

    The car felt more responsive with it though and i have recently refitted the orginal CAT since i am selling my car.

    The decat pipe i had is now sitting in my garage gathering dust if u want to make me an offer for it although u would still have to find someone to fit it.

    I have a different engine from yours if that makes a difference though...
