That SS kit looks really nice if it matches your engine. FWIW, it wouldn't match my Universal M4-30. So I'm replacing the exhaust riser mixing elbow with the same thing that lasted for 34 years. It has an iron 3 bolt flange at the engine, iron pipe nipples and aluminum casting for the elbow made by Barr. It's much more compact than a SS aftermarket elbow would be. Parts should arrive in a few days. I may get some SS nipples for it, if they're not too pricey. Chuck Scheaffer, Resolute 1989 C&C 34R, Annapolis
