The Dieselr Aluminized Turbo Back Exhaust Single (2003–2004 5.9L Cummins) is designed for Ram 2500 and 3500 owners who want strength, simplicity, and proven performance. Built from heavy-duty aluminized steel, this system improves exhaust flow, lowers EGTs, and provides long-lasting resistance to heat and corrosion.

This 4 inch, 5 inch  turbo back system is engineered for clean fitment and efficient performance. Precision mandrel bends and welded flanges ensure smooth flow and OEM-style alignment, while the aluminized finish provides protection from rust, road salt, and daily wear.

Perfect for tow rigs, work trucks, and performance builds alike, the Dieselr Aluminized Turbo Back Single gives your 5.9L Cummins the breathing room it needs to perform under real-world load. It’s the kind of system built to last—not for looks, but for results.

Built. Tested. Proven. That’s Dieselr.
