BD DIESEL 1048006 ISX CUMMINS T6 CERAMIC COATED EXHAUST MANIFOLD – SIGNATURE 600 / ISX PRE-2002

Product Description

The BD DIESEL 1048006 ISX Cummins T6 Ceramic Coated Exhaust Manifold is a heavy-duty 3-piece manifold designed for Cummins Signature 600 / ISX (Pre-2002) applications using a T6 turbocharger. This manifold is engineered to solve one of the most common heavy-duty diesel problems—cracked or leaking factory manifolds—by using a thick-wall, high-silicon ductile iron casting and a multi-piece design that helps reduce stress, warping, and future failures.

The ceramic coating helps manage heat and improves durability in high EGT conditions. The 3-piece layout allows controlled expansion and contraction under load, reducing the likelihood of cracking while supporting strong exhaust flow for towing, fleet use, and heavy commercial duty. If you’re replacing a leaking or broken factory manifold—or upgrading for reliability—this BD Diesel manifold is the long-term solution.

Is this manifold a direct replacement for the factory ISX manifold?

This manifold is designed as a heavy-duty replacement solution for Cummins Signature 600 / ISX (Pre-2002) engines using a T6 turbo configuration.

Why is a 3-piece manifold better?

A multi-piece manifold helps reduce stress during heat expansion and contraction, which can significantly reduce cracking and leak issues over time.

Does the ceramic coating help performance?

The ceramic coating helps manage heat and improves durability in high EGT environments. It also helps protect the manifold surface and maintain reliability under heavy load.
