What would cause exhaust manifolds to get orangish red hot on 94 toyota 4 runner?

[Edit]

How is your performance?  You may have a stuck valve or just an obstruction in your exhaust.

Plugged converter possibly or other exhaust restriction.

Answer

exhaust is very very hot, because of this, your exaust manifolds/headers are going to get very very hot, especially if you tend to run high RPMs. if everything else like throttle response is fine, i wouldn't worry
