Reproduction Ram Air Manifolds, quality?
I've had Ram Air Restoration Oversize (2 1/2") "D" port manifolds on my car 11 years (45,000 miles) and have not had one problem. Have had the down pipes (Pypes 2 1/2") off and on at least half a dozen times and never had a exhaust leak problem. I had the manifolds a year and sent them back for ceramic coating and that has held up excellent, also. Used the composition gaskets that came/were sold with them and have had manifolds off couple times and reused gaskets without and leak problem, too.
