A Proven Fix for a Known Weak Spot

If you’ve spent any time wrenching on a 12-valve Cummins, you already know that the stock exhaust manifold is one of the first parts to show its age. The ATS T4 3 Piece Pulse Flow Exhaust Manifold Kit offers a reliable, high-performance solution for your 1994–1998 Dodge RAM 2500 or 3500 with the 5.9L engine. Built from high silica moly cast material, this manifold holds up where the factory unit tends to crack and warp under heat. The three-piece pulse flow design is all about improving exhaust gas velocity, which means faster turbo spool-up and smoother power delivery—especially important when you're towing or running a performance setup. Plus, the ceramic black coating helps keep under-hood temps in check while giving your engine bay a clean, finished look.

Designed to Fit Right and Last Long

This kit comes with everything you need to get it bolted up without a hassle. The T4 turbo flange supports a wide range of turbocharger upgrades, and the non-wastegated design makes it a solid option for simplified, performance-minded builds. One of the standout features is the patented ball flange, which helps reduce the stress between the manifold and turbo, giving you better durability and fewer leaks down the road. If your current manifold gaskets are still in good shape, you can reuse them, making the install even more straightforward. Whether you’re building a workhorse or just want to eliminate one of the common failure points on your 12V Cummins, this manifold brings performance, reliability, and peace of mind together in one smart package.
