Replace the old, cracked, or damaged exhaust manifold on your 1999-2003 Ford 7.3L Powerstroke and get your engine running right. For greater durability, most of the aftermarket exhaust manifolds offered are manufactured with high-silicon ductile iron. Due to heat cycles and age, exhaust manifolds can be prone to cracking and cause boost or exhaust leaks. This can rob you of power and reduce engine efficiency. BD-Power, Dorman, AFE, ATS, and many more are just some of the manufacturers you can find.
