1998.5-2018 Cummins T4 Wastegated Exhaust Manifold (1045947-T4)

Fits

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.
