The 2019–2026 Cummins aFe ATLAS 5" DPF‑Back Exhaust System with Black Exhaust Tip is a direct‑fit performance exhaust upgrade designed specifically for Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel. Built with mandrel‑bent 5‑inch aluminized steel tubing, this exhaust system replaces the restrictive factory DPF‑back sections to improve exhaust flow, lower exhaust gas temperatures, and enhance power delivery without cutting or welding. Factory‑style hangers and high‑quality clamps make installation straightforward and bolt‑on.
The system is finished with a 7‑inch black stainless steel exhaust tip featuring an aFe Power logo plate, giving your truck a bold look while showcasing the performance upgrade.
