08-12 Dodge 6.7L Exhaust Manifold

The BD DIESEL 08-12 Dodge 6.7L Exhaust Manifold is a heavy-duty cast ductile iron component engineered for the Dodge Cummins turbo diesel platform. This pulse-style manifold replaces the factory exhaust manifold on 2008–2012 Dodge Ram trucks equipped with the 6.7L Cummins diesel engine, delivering improved exhaust flow and thermal management for engines operating under sustained load.

Constructed from ductile iron, this manifold offers superior heat tolerance and structural integrity compared to lighter materials, critical for diesel applications where exhaust temperatures regularly exceed 1,000°F. The pulse-style design optimizes scavenging efficiency by leveraging pressure wave dynamics to enhance cylinder evacuation, a technique widely employed in high-performance diesel tuning. At 27.3 lbs, the manifold integrates directly with the OEM mounting points and turbocharger inlet, maintaining factory fitment while addressing common wear and corrosion issues found in aging factory manifolds.

This replacement is essential for Cummins diesel owners who experience manifold cracking, exhaust leaks, or degraded turbo response stemming from restrictive or damaged factory components. The BD DIESEL manifold is particularly valuable for trucks used in towing, hauling, or sustained high-rpm operation where thermal stress on exhaust systems is magnified. Proper exhaust manifold condition directly impacts turbocharger performance, fuel economy, and engine longevity in diesel powerplants.

BD Diesel is recognized within the Cummins diesel community for manufacturing durable aftermarket exhaust and fuel system components. The 6.7L Cummins platform dominated light-duty diesel truck sales throughout the 2008–2012 model years, and OEM manifold replacement remains a common maintenance need as trucks age beyond 100,000 miles.
