    i dont know about maines laws but if you removed your cat here in PA you would not pass inspection.unless you "know somebody" that can get you a sticker.

    On a 91 truck I believe there is only one o2 sensor just upstream of the cat. If this is the case exaust modifications downstream from the o2 sensor should have little to no effect on it.

    If you arne't having problems, leave it be.

    You know the old adage, "if it ain't broke, don't fix it". Well, for automotive I think that should be changed to "if it ain't broke, don't change it, because you'll find something else that's screwed up in the process" /forums/images/graemlins/smile.gif

    I would leave it alone or you could replace it with a Catco for about 50 clams
