The Diamond Eye Performance K4214S 4-Inch Turbo-Back Dual Exhaust System is engineered for 1998.5–2002 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L 24-valve Cummins diesel engine. Constructed from durable T409 stainless steel, this system is designed to improve exhaust flow, reduce exhaust gas temperatures, and enhance overall engine efficiency for towing, daily driving, and performance applications.
This turbo-back dual exhaust system features a C.A.R.B.-exempt diesel downpipe and is built to fit all cab and bed lengths using factory mounting locations. The 4-inch tubing diameter allows the Cummins engine to breathe more efficiently, delivering improved throttle response and a deeper, more aggressive diesel exhaust tone while maintaining long-term corrosion resistance. Sold as a complete turbo-back system.
