Description
Description
The Dieselr Aluminized Downpipe Back Exhaust (2017–2019) is a precision-built 4-inch system designed for high-demand diesel platforms that need cleaner flow and reliable construction. Made from heavy-gauge aluminized steel, this exhaust system delivers consistent performance and dependable durability under continuous heat and load.
Each Dieselr exhaust is mandrel-bent for uniform airflow and TIG-welded to prevent leaks and stress fractures. The aluminized finish resists corrosion, salt, and moisture—ideal for fleets and performance-driven diesel setups. Installation is direct and secure thanks to factory-style mounting points and reinforced hanger alignment.
Purpose-built for reliability, Dieselr aluminized systems are field-tested for long-term strength and precision fitment—steel engineered to work hard and last longer.
Key Features
- 4″ aluminized steel construction for maximum strength and heat resistance
- Mandrel bends for smooth, unrestricted flow
- OEM-style fitment for fast installation and tight seal
- Corrosion-resistant finish for extended service life
