    lambda on z18xe?

    is it befor or after the cat? im thinking of getting a new manifold and i presume i can run it without a cat problem free if its befor the cat on the standard unit, but if its after im going to have some problems with the engine rejecting it? cheers!

    That would be a difficlut job put it back, since the cat is part of the exhaust manifold

    your going to use alot of gaskets up and also run the risk of cracking your maniflod and breaking a lug but too.
    If i was you i'd try and find a proper manifold with sports cat to fit.

    Cheepest manifold ive found with sports cat is about £800 so its not worth it for what gains you will get.
