    Default Pesky Exhaust Leak

    Hey all,
    today i put a pair of edlebrock headers on my truck with a few buddies. the removal of the manifold and installion went without a hitch until i fired her up and there is an annoying exhaust leak. we localized it to the flang above the right cat. we took it apart twicd and even used a new gasket. someone please help. would a gasket sealer be a good fix or should i take it to a shop???

    i remember a while back at our autoshop, we had done the headers on an old school blazer, and we put this little orange stuff on the gaskets, so they would seal better.

    im not sure if it would be good though.
