BD Diesel Performance Exhaust Manifolds

Specifications

• For Dodge Ram 88-98 12 Valve & 98-02 24 Valve & 03-07 5.9L: Horsepower creates heat pure and simple. On a high-output engine like the Dodge-Cummins, high exhaust gas temperature (EGT) is enough to cause the stock exhaust manifold to crack. BD's New Pulse Manifold for '88-02 applications (two-piece offset Pulse available for '03-06 applications) is cast from high-silicon ductile iron, which can withstand extremely high temperatures, as well as the additional weight created, by bigger single or twin turbo systems. Two expansion joints allow the manifold to expand and contract without cracking or exhaust leaks.  Of course, the Pulse wouldn't be a BD product if it didn't offer the benefit of improved performance. As its name would suggest, this manifold is pulse-tuned for more efficient combustion chamber evacuation and higher exhaust flow. The result is quicker turbo spool-up, reduced backpressure, more power and better fuel economy.   All Pulse exhaust manifold kits come assembled and are complete with stainless steel hardware to resolve the issue of loose or lost fasteners (gasket kits available separately). Add a BD X-Hale exhaust system for even greater performance gains!
• For Chevrolet / GMC Duramax 6.6L:  Improve exhaust flow, reduce exhaust gas temperature (EGT) and realize greater power gains with the new "Full Bore" driver's side exhaust manifold for the '01-'07 GM Duramax. You may not know it, but the factory driver's side manifold is pinched down to allow clearance for the steering shaft, which actually isn't required. As a result, this manifold flows 80% of the passenger side manifold. The BD Full Bore exhaust manifold restores exhaust flow to match the passenger side, and is a direct, bolt-in replacement for the factory part (GM gasket required). The BD Full Bore manifold is made from high-silicon ductile iron to resist cracking from high temperature and vibration, and is even tapped to accept the most popular EGT probes.   The BD Big Bore exhaust manifold is a great compliment to BD's new SuperMax turbo upgrade kit and stainless steel X-Hale exhaust systems.
