Description
Description
The Dieselr Aluminized Downpipe Back Exhaust (2011–2015) is designed for serious diesel owners who want proven airflow gains and rugged dependability. Constructed from 4-inch, 5-inch heavy-gauge aluminized steel, this system provides a clean, unrestricted path from turbo outlet to tail section—improving exhaust velocity and lowering EGTs under heavy load.
Each Dieselr exhaust is mandrel-bent for precise geometry and TIG-welded for lasting strength. The aluminized coating resists corrosion, heat, and salt, ensuring long-term reliability in demanding conditions. Its OEM-style alignment and mounting points make installation simple, secure, and clean with no modifications required.
Built for performance and longevity, this system defines what Dieselr stands for—straightforward design, precision fitment, and real-world durability tested on working diesels.
Key Features
- 4",5" aluminized steel for maximum strength and corrosion protection
- Mandrel bends for smooth, consistent exhaust flow
- Factory-style hanger fitment for simple, secure installation
- Built to handle heat, load, and high-pressure applications
