ATS Diesel 98.5-02 5.9L Cummins T3 3-Piece Pulse Flow Exhaust Manifold Kit w/ Gaskets & Hardware

If you're looking to get the most out of your 1998.5-2002 5.9L Cummins, especially if you're planning on adding a larger turbo or increasing boost, upgrading your exhaust manifold is a smart move. The stock manifold can be a bottleneck, especially under higher loads. This 3-piece Pulse Flow exhaust manifold kit from ATS Diesel is designed to help your engine breathe more freely, which can lead to improved turbo spool and better overall performance.

ATS Diesel built this manifold in three sections to allow for expansion and contraction without cracking, a common issue with single-piece aftermarket manifolds, especially under the high heat of a diesel engine. The Pulse Flow design aims to improve exhaust scavenging by directing pulses from each cylinder more efficiently towards the turbo. This means the turbo can spin up faster and maintain boost more consistently. The kit comes complete with all the necessary gaskets and hardware for installation, making it a comprehensive solution for your upgrade. It's constructed from durable cast iron, built to withstand the demanding conditions of a high-performance diesel engine.

This manifold is specifically designed for a T3 turbo flange, so make sure your turbocharger uses that connection type. Because this part is not CARB approved, it cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding torque sequences and any other requirements for a successful installation.
