The Dieselr Aluminized 4" Cat & DPF Race Pipe (2007–2012 6.7L Cummins) is built for Ram 2500 and 3500 owners who demand reliability and real-world performance. Constructed from heavy-gauge aluminized steel, this system improves exhaust flow, lowers EGTs, and stands up to the abuse of towing, hauling, and daily work.

Engineered for precision fitment, the Dieselr race pipe installs directly to OEM hangers with pre-welded flanges and smooth mandrel bends for a clean, factory-style finish. Its aluminized construction resists corrosion and heat while maintaining strength through years of hard use.

Whether you run a tuned work truck or a competition-built 6.7L Cummins, this pipe delivers consistent flow and reliable performance under load. Tested on real trucks and proven across thousands of miles, it’s designed to perform—day in and day out.
