Hey guys this may seem like a real stupid question but do the ball and socket flanges on our exhaust pipes use any sort of doughnut gasket? I would think the metal on metal wouldn't seal perfect but I have no idea. I am finishing buttoning up my xpipe and want to know if I should find some gaskets for it. Thanks.
I've never seen any. Usually they just tighten up enough to seal. I know the 4.6 cars had a gasket for one of the header flanges where it meets the H pipe, but that was because it wasn't a ball and socket type flange.
You can put some black RTV on it if you want to. I am thinking about it on mine, cause I cant seem to get it just right. Have a buddy that has always done it, and never had any burning issues or anything.
