ATS Diesel 03-07 5.9L Cummins 2-Piece T3 Pulse Flow Exhaust Manifold Kit w/ Gaskets & Hardware

If you're looking to get the most out of your 03-07 5.9L Cummins, especially if you've modified your engine or are planning to, upgrading the exhaust manifold is a smart move. The stock manifold can be a bottleneck, restricting exhaust flow and limiting how efficiently your turbocharger can spool. This ATS Diesel 2-Piece T3 Pulse Flow Exhaust Manifold Kit is designed to address that limitation, helping your engine breathe more freely.

This manifold is built in two pieces, which helps to manage the intense heat generated by the Cummins engine. By splitting the manifold, ATS Diesel allows for more controlled expansion and contraction, reducing the risk of cracking that can plague single-piece designs under extreme conditions. The T3 flange provides a solid mounting point for a variety of aftermarket turbochargers, and the pulse flow design is engineered to direct exhaust pulses more efficiently to the turbo's turbine wheel. This can lead to improved turbo spool-up times and a more responsive feel from your engine. It’s a well-built piece that’s made to handle the demands of a performance-oriented diesel truck.

This kit comes complete with all the necessary gaskets and hardware for installation, making it a comprehensive solution for your exhaust manifold upgrade. Please note that this manifold is not CARB approved and cannot be shipped to California. It is also subject to California's Prop 65 warning.
