    yeah, another question about cats

    so, I am thinkin of either ditchin, hollowing, or changing my cat.


    if I change it to like a high flow magnaflow, will volume increase?

    if I hollow it, will it throw codes?

    if I put in a straight pipe, what do I need to not throw any codes?

    If you change the cats at all...it will throw codes.

    The rear O2 codes will need to be turned off via HPTuners, LS1Edit, etc...

    If it is like the LS1 cars, it won't change anything.
