1962 409 exhaust piece not sure what its called and what's it function

[4speedman]

I generally toss 'em anyway they were always a PITA .

Back when these cars were daily drivers i always took the flapper out and filled the holes with short bolts these things like to rattle after some use

I recall taking the flapper out and shaft and welding hole's shut on one of them.

Am I dreaming or didn’t Walker Mufflers have a piece to eliminate the exhaust riser system and not “move” the head pipe?

My 65 has the heat riser on the passenger side which I replaced with a delete spacer, never liked them

Robert, Show-cars sells a spacer to replace the heat riser assembly.

No place for it in the headers on the race car.
I also block off the exhaust passage at the intake flange to keep the heat away from the intake and carburetor.
