Default Oval manifold ports-round pipe
What is the easiest way to mate a round pipe to an oval port on an Exh manifold flange? The Oval is 2 1/4" wide and only 1 1/2" tall. Mild steel flange mild steel pipe.

The way i did it with ease was to heat up the pipe that needs to be ovaled(sp) in a bench vise, and keept it warm as you slowly compress it until it is at the desired shape.

Thanks!

How about when trying to use pipe fittings instead of exhuast pipe? They aren't really Bendable are they?

you just need a big enough vise and heat the ---- out of the pipe

I am inclined to just use 16 gauge mild steel mandrel bends. Wouldn't that work?

Oh, it's for twin 14B turbos on a V6.
