HFC with the ability to use the factory crush ring?

Neo187H · 07-12-2012, 09:49 AM

Do any of the HFC options have the flange on the portion that meets the exhaust manifold to allow the use of the factory crush gaskets? I have had horrible luck with the flat flange and sealant method and am looking for a change.

I know that Motordyne offers their new ART pipes with the flange but I'm looking for HFC to possibly avoid some of the black soot that covers my bumper within a day of washing.

My Stillen HFCs installed last week used the ring

I just used header gasket material - no leaks.
