Description
The Dieselr Aluminized 4″,5″ Cat Back Exhaust (2004.5–2007) is built for durability, precision fit, and smooth exhaust flow. Crafted from 4-inch , 5-inch heavy-gauge aluminized steel, this system reduces backpressure, stabilizes EGTs, and delivers consistent performance for high-load or daily-driven diesel builds.
Each Dieselr system is precision-welded and mandrel-bent to maintain uninterrupted flow from the catalyst outlet to the tail section. The aluminized coating protects against corrosion, heat, and road debris, ensuring long-term reliability in any environment.
Installation is straightforward with OEM-style hangers and clamps for a tight, vibration-free fit. The sound is refined and balanced — a clean tone that reflects true Dieselr engineering.
