      Enhanced Exhaust Performance. Improved exhaust flow and long-term durability are essential for demanding diesel applications, and the BD Power Exhaust Manifold Kit delivers both through a heavy-duty design engineered to outperform factory components.

      Construction and Appearance. Built from heavy-duty cast iron, this exhaust manifold kit is engineered to provide exceptional strength, improved thermal stability, and outstanding resistance to cracking under demanding operating conditions. The high-temperature matte black finish protects the manifold surfaces while polished chrome accents provide a clean, professional appearance.

Supplied with manifold gaskets, up pipe gaskets, fasteners, and premium installation hardware, the complete kit delivers the quality, durability, and precise fit expected from a premium direct replacement exhaust system component.

      Installation. Installation is designed as a direct replacement using the included gaskets, fasteners, and mounting hardware. Position each manifold carefully before tightening the hardware evenly to ensure proper sealing and alignment with the exhaust system. Verify that all gasket surfaces are clean and that every fastener is torqued according to the appropriate service specifications before operating the engine. Inspect the completed installation for exhaust leaks and proper clearance around surrounding components after the initial heat cycle.

The warranty reflects the manufacturer's confidence in the quality of the materials and workmanship while providing additional peace of mind for long-term ownership.
