1998.5-2002 Cummins 5.9L BD Diesel T3 Stock Exhaust Manifold (1045947)

The BD-Diesel 1045947-T4 Exhaust Manifold is a perfect addition to a stock truck or someone building a custom turbo setup. The thick walled casting and built-in expansion joints give the manifold room to exand and contract without the risk of cracking while the pulse design increases exhaust flow that results in a faster spool, less backpressure, increased fuel economy, and increased power. The wastegate flange is perfect for those that want to run an external wastegate setup, but includes a block-off plate for those running the internal wastegate setup.
