Dieselr Aluminized 4" Turbo Back Exhaust Single | Dodge 2500/3500 5.9L Cummins (1989-1993)

The Dieselr Aluminized 4" Turbo Back Exhaust Single (1989–1993 5.9L Cummins) is built for the original generation of Ram 2500 and 3500 diesels—known for torque, toughness, and workhorse reliability. This system delivers improved exhaust flow, lower EGTs, and consistent performance in a design built to last.

Crafted from heavy-duty aluminized steel, it’s engineered for long-term resistance to rust, heat, and road wear. Precision mandrel bends maintain smooth flow from the turbo back, while the single-pipe layout bolts directly to OEM hangers for a clean, factory-style fit.

Ideal for classic diesel restorations or daily work trucks, this 4-inch system gives your first-gen Cummins the airflow and durability it deserves. Every Dieselr exhaust is tested for fit, performance, and sound—because reliability is earned, not advertised.

Strong. Simple. Proven. Dieselr.
