What exhaust pipes on Iron exhaust manifolds?

neurotoxin312 · Aug 24, 2015

Hello all. So I am currently rebuilding my exhaust system on my 71 Mustang 351W. I will be purchasing some doorman exhaust manifolds and can't seem to find that pipe (with 2 flanges) to connect to the exhaust manifold. Anyone have any idea what its called and where I can find them? btw I will be purchasing Doorman 674 Exhaust Manifolds.

It's a "Y" pipe for single exhaust. An ."H" pipe for dual exhaust. Check NPD catalog for detailed views.

If his engine is a windsor, he's going to have a hard time finding them, and will likely need an exhaust shop to make them as the car wasn't offered in that configuration. Maybe the 302 pipes could be altered to fit, but the 351 is wider

I am also looking for replacement exhaust manifolds. Has anyone had experience using Dorman 674-165 & Dorman 674-169 for replacements on a 351w?
