BD Diesel 2003-2007 Dodge Ram Cummins 5.9L Common Rail Aftermarket 2 Piece Exhaust Manifold #1045987
Cracked or leaking exhaust manifold is a common problem with many Dodge Cummins 5.9L Diesel's. Caused by rapid heating and cooling the exhaust manifold will weaken over time warping and eventually cracking from the stress. This is why BD Diesel designed their exhaust manifolds with a ball joint and webbed runner design to allow for metal expansion while running higher temperatures, providing superior strength over the stock manifold. Runner size does not go beyond the size of the exhaust ports on the head because when the runners are larger, the velocity to drive the turbo is lost due to the expansion and temperature in the exhaust manifold reduces the turbine drive pressure needed for turbocharger response.
- Allows For Expansion During High Temperatures
- Improved Airflow
- Decrease Warping and Cracking Issues
