BD Diesel ceramic-coated exhaust manifolds are built for Caterpillar 3406E (1993–1998) and non‑ACERT C15 (1999–2003) engines with a T6 turbo mount, providing a heavy-duty three-piece ductile iron casting designed to resist cracking. Coated inside and out for temperature control and smooth finish, these manifolds suit owners replacing cracked units or upgrading to support a T6 turbo application.
