Description
Description
The Dieselr Aluminized Cat & DPF Race Pipe (2011–2015 6.6L Duramax LML) is designed for GMC Sierra and Chevy Silverado 2500/3500 HD owners who demand a reliable, high-flow exhaust solution built for performance and longevity. Made from heavy-duty aluminized steel, this race pipe improves exhaust velocity, reduces restriction, and helps maintain cooler EGTs under load.
Each Dieselr pipe is mandrel-bent for consistent flow and precision-welded to ensure strength and leak-free performance. The aluminized coating provides superior resistance to heat and corrosion—ideal for heavy-use and harsh weather conditions. Designed to mount cleanly to OEM locations, installation is straightforward and secure.
Every Dieselr product is tested on actual Duramax trucks for real-world fitment and performance. This race pipe delivers what matters—durability, flow, and a clean, functional design that lasts.
Key Features
- Aluminized steel construction for lasting corrosion protection
- Mandrel-bent tubing for smooth exhaust flow
