Stock exhaust manifolds coming from an 2005 Ford F350 - Powerstroke Diesel.
They were replaced as the engine adopted a build time and were replaced with high performance/flow manifolds.
Nothing wrong with them. Came off of my truck with a stock tune so no too much heat.
Created with black exhaust manifold paint which can hold up against temps up to 2000F. They feature new Ford OEM bolts but you will certainly need to purchase new gaskets and also spacers.
