Description

Exhaust pipe flange gasket, for use with stock cast iron exhaust manifolds.
Cougar applications: all 289/302 engines 1967-69, 390 engines 1967-69, and 427-4V 1968 GT-E engine which uses 390 exhaust manifolds.
Mustang and most all other Ford engines: 289/302 engines 1965-69, 390 engines 1967-69
Fits between exhaust manifold and header pipe (H or Y pipe) steel construction, 2-1/32 inch inside diameter, tapered top and bottom, smooth inside. Sold individually, two required per car.
These will work with our reproduction H and Y pipes.
Replaces Ford part number C6AZ-9450-D.

Bill (1969 Cougar)

Installing on 1969 base Cougar. 351W

This piece seemed to fit okay on the pipe side, but when fitting it to the manifold I thought it seemed to crank down a long ways before it actually tightened up. I chalked it up to an original exhaust pipe having been flared differently, but when I got a replacement H pipe, it tightened down the same way. With things back out again I test fit this against the manifold and found it nearly fell in. This may be the right piece for a 289/302, but it is certainly too small for a stock 351 application despite the description.

Added to my order for the complete exhaust system.(1967 289-4v) Excellent fit. Highly recommended.

Did the job and it's cheap!

I had a crack in my exhaust manifold. Upon tearing into it, I found the exhaust flange was probably original and being in the Northeast, very pitted and rusty. I had an exhaust leak at that joint so I figured I'd replace it while I was in there. This replacement fit the bill perfectly. It fits perfectly and sealed against the tailpipe and my new used manifold.
