The aFe Twisted Steel Header Turbo Manifold (T3) is a high-performance exhaust component designed specifically for 1998.5–2002 Dodge Diesel Trucks equipped with the 5.9L inline-six 24-valve Cummins engine. Constructed from mandrel-bent 304 stainless steel tubing, it features 1-3/4" head pipes stepped up to 2" for optimized exhaust flow. The header includes a 1/2" laser-cut T-3 divided flange to enhance turbocharger response, delivering quicker boost and improved throttle response. TIG welding ensures strength and durability, while integrated 1/8" EGT ports allow for auxiliary temperature monitoring. This design increases exhaust velocity, resulting in higher usable torque and horsepower gains.
This turbo manifold is a direct replacement for the factory exhaust manifold on compatible Dodge Diesel trucks from 1998.5 to 2002. It is engineered for street and performance applications where improved turbo spool and engine efficiency are desired. Installation is straightforward, utilizing existing mounting points and hardware. The system is ideal for enthusiasts seeking enhanced power delivery without sacrificing reliability. Its robust stainless steel construction and precise fitment make it suitable for daily driving, towing, and light-duty performance upgrades. The package includes the header manifold with EGT ports ready for sensor installation.
