    So I've taken all the honeycomb out of my exhaust cat, what do I do with the lambda sensors. Not to sure on what people mean by sleeving and what difference it makes

    If the Cat is still there, you have two choices.

    Plug it back in to the orignal hole or purchase a blanking screw and a lamba sleeve.

    Effectively the blanking screw blocks off the existing hole and the sleeve is just a small piece of metal which the existing lamba screws into and you then mount it somewhere it can get clean ear, such as near the engine bay.

    It puts on your EML light mate,the 2nd sensor needs to read clean air.

    that's because you've sleeved it lol

    I don't see why your trying to sleeve the lambdas anyway you've still got the two holes for the lambdas so use them, you sleeve the lambdas when you buy a new exhaust and it only has one lambda hole

    Because its cheaper to just strip the cat out?

    Any ways op. You need a m18 blanking plug for the second lambda and a sleeve for the second lambda. With the core not in the cat the second lambda will throw a spaz as the air will still be dirty.

    Also hope you weighed in the old core as there worth like £10 so would have paid for the blanking plug lol.
