Anyone have an old set of catalytic converters for a 348? Looking for a dead pair for a project I am working on. Do not care if the units are blocked, empty, etc. Need good inlet and outlet as well as not distorted. Do not want to cut up the good set on my car. Not planning to hollow out or anything illegal. May have them re-cored with newer hi-flow material if cost effective. Will pay a fair price and shipping. Will post results if successful. Thanks.
