Any ideas on sealing an exhaust leak on my 1990 Bronco? It's got stock exhaust manifolds and stock Y-pipe coming from there...and I've got an exhaust leak from this mating surface. Is there some sort of gasket and/or sealant I can apply to seal this area?

 

no, and there is no gasket there currently either. the manifold is proably warped so you will either need to get a new manifold or take this op to upgrade to a set of headers

 

so I suspect the tailpipe piece. I recently removed the headers because I couldn't get them to seal properly in this area.
