BD Diesel Pre-2002 ISX / Cummins Signature 600 ISX T6 Ceramic Coated Exhaust Manifold

If you're dealing with cracked or leaking exhaust manifolds on your Pre-2002 ISX or Cummins Signature 600, it's time to consider an upgrade. This heavy-duty exhaust manifold from BD Diesel is built to handle the high temperatures and smooth out exhaust flow, especially if you're looking to install a new T6 turbo. BD Diesel has a long history, starting with exhaust brakes back in 1972, and they focus specifically on diesel performance parts.

This manifold is constructed from thick-walled, high-silicon ductile iron, a material chosen for its durability and resistance to cracking, especially under extreme heat. The 3-piece design further helps prevent the common cracking issues found in stock manifolds, which can save you from future repair costs and downtime. It's ceramic coated inside and out, not just for a smooth finish but also to help manage temperatures, rated up to 1800 degrees F. BD Diesel used computational fluid dynamics to design this manifold, aiming for improved exhaust flow, and they've seen an average increase of 9.3% compared to stock ports. The exhaust ports are also gasket-matched to ensure a good seal and efficient flow into your turbo.

This kit includes everything you need for installation, including 16 studs and spacers, crossover tube gaskets, and exhaust manifold gaskets. The longer exhaust studs are designed to improve thermal durability, and the thick spacers are black oxide coated. This manifold is specifically designed to fit Borg Warner 171700 and 171710 turbos, as well as factory T6 Holset turbos, and is a perfect match for BD Diesel's Scorpion Turbo Kit. It replaces OEM part number DC3Z9431A for the left side.
