hot exhaust on Ford 460 Sign In

The exhaust pipe on pasenger side of a Ford 460 is getting red hot. What could be causing this?

Not sure what vintage. Does this use a choke plate type heat riser in the exhaust between pipe and manifold?

It's not the exhaust manifold, it's the actuall exhaust pipe

I understand. If the engine uses a heat riser it diverts most of the exhaust to the other side thru the intake manifold. Intake may cool that exhaust on the way a bit and the trickle amount remaining doesn't flow fast enough so may get red hot. Hard to say for sure. Heat risers frequently used a temp sensitive spring or maybe a rod to a diaphragm - I forget the assorted ways that might have been used on a 460,
