The Dieselr Aluminized 4" Turbo Back Exhaust (2003–2005) delivers proven airflow and durability for serious diesel builds. Constructed from 4-inch heavy-gauge aluminized steel, this system offers smoother exhaust flow, stable EGTs, and consistent back-pressure control across load conditions.

Every Dieselr system is precision-welded and mandrel-bent for uniform flow from the turbo outlet to the tail section. The aluminized coating resists corrosion and heat fatigue, ensuring years of reliable operation in towing, work, or performance environments.

Installation is direct and clean, utilizing factory-style hanger points and a single-exit design for a secure, vibration-free fit. The sound is deep and balanced—engineered for strength without harsh cabin resonance.
