Hall Headers / Ansa Mufflers Combo

They had a donut in them .. but I always had a problem with them leaking ... I cut the muffler flair end off and welded on a 3 bolt header flange and then used that new ALUMINUM TYPE header gasket and havent had a problem ...since that time.

Mine have beveled edge donuts but the key thing is the short pieces of exhaust pipes that the muffler shop put through the center of them. Without the inside pipe they will leak because the gasket needs to be compressed on both sides but have the pipe inside to keep it from crushing in on its self.

mine has the doghnut, and 3 bolt flanges.
Th trick is to make sure they are clean and pull the fanges up evenly, works for me.

Big Bore exhaust to header.

NAPA part number 31 381 about $9.00 ea.

Gasket has about a ¼” steel ring (inside of the “donut”) that extends out of one side of the donut. Works well.
