This BD Diesel Performance exhaust manifold is specifically engineered for pre-2002 ISX Cummins engines and Signature 600/ISX T6 applications. Crafted from high-silicon ductile iron, it features a three-piece thick-walled design that prevents cracking and ensures durability under high thermal loads. The ceramic coating on both the inside and outside surfaces provides a smooth finish while offering superior temperature control, withstanding temperatures up to 1800 degrees Fahrenheit. This design enhances exhaust flow, contributing to an average increase of 9.3% in flow capacity compared to OEM standards, which translates into improved engine efficiency and performance.
Designed with precision, the manifold includes gasket-matched exhaust ports, longer studs for enhanced thermal durability, and a machined thicker bolting flange for secure attachment. It fits Borg Warner 171700, 171710, and factory T6 Holset turbos, making it an ideal upgrade for BD Scorpion Turbo kits. The inclusion of 16 studs and spacers ensures compatibility with BD Scorpion kits and other high-performance applications. The high-silicon ductile cast iron construction, along with black oxide-coated spacers and high-temperature POR 15 black coating, ensures longevity and resistance to warping or heat-related failures. This exhaust manifold is designed using computational fluid dynamics to maximize flow efficiency and performance.
Certified with SEMA certification and compliant with CARB EO No. D-553-17, this product is 50-state legal, offering a legal and reliable upgrade for diesel performance enthusiasts. The package includes the exhaust manifold, crossover tube gaskets, studs, and spacers, providing all necessary components for installation. The durable construction and high-temperature coating make it a reliable choice for demanding fleet and performance applications, ensuring long-term drivetrain durability and optimal thermal management.
