The T-4 Stainless Diesel Cummins Exhaust Manifold is specifically designed for 24v sled pullers and high-performance enthusiasts. Manufactured using advanced shell molding casting technology, this manifold offers a smooth finish both inside and out, which greatly improves airflow compared to traditional casting methods. This technology surpasses the old, rough 60-grit sandpaper-like casting found in other exhaust manifolds.

With a 3/4-inch thick center section, this manifold allows for custom porting, giving you the flexibility to tailor it to your specific performance needs. The thick wall casting helps retain heat within the manifold, contributing to improved efficiency and maintaining optimal exhaust temperatures.

The 1.650-inch inside runner sizing is maintained consistently to the center outlet, supporting high flow and enhancing the performance of large turbos. This design results in faster turbo spool-up, improving response by several hundred RPMs. The manifold also increases horsepower, broadens the powerband, and, when used with similar modifications, can enhance fuel economy.

The exhaust manifold features large 1.65-inch ports that run the full length to the collector foot, ensuring superior flow compared to competitors. This design not only improves performance but also ensures a perfect fit and finish for your Cummins engine.
