Dieselr Aluminized Downpipe Back Exhaust Single | 2500/3500 6.6L GM DURAMAX LML (2015.5-2016)

The Dieselr Aluminized Downpipe Back Exhaust (2015.5–2016) is built for real-world performance and long-term reliability. Crafted from 4-inch, 5-inch heavy-gauge aluminized steel, this system delivers smoother exhaust flow, lower EGTs, and a bold, refined tone built for high-load conditions.

Each Dieselr exhaust is mandrel-bent to maintain unrestricted airflow and precision-welded for lasting strength. The aluminized coating resists corrosion, oxidation, and heat stress, making it ideal for harsh working environments and daily-driven diesel applications alike.

With factory-style hanger alignment and secure clamping points, installation is fast, clean, and reliable—built to fit right and last long. Dieselr aluminized systems are tested and tuned for flow, efficiency, and strength that never quits.
