Description
Description
The Dieselr Aluminized Downpipe Back Exhaust Single (2007.5–2010 6.6L Duramax) is designed for Chevy Silverado and GMC Sierra 2500/3500 HD owners who demand real performance and lasting reliability. Built from 4-inch heavy-duty aluminized steel, this system delivers improved exhaust flow, reduced EGTs, and a strong, deep diesel tone that’s built to last.
Each Dieselr exhaust system is mandrel-bent for consistent, unrestricted flow and precision-welded for long-term strength. The aluminized finish provides corrosion and heat resistance, making it ideal for both work trucks and performance builds. With OEM hanger alignment, installation is quick, secure, and rattle-free.
Tested on actual 6.6L Duramax LMM platforms, Dieselr aluminized systems deliver proven gains in flow and durability—built for owners who rely on performance, not promises.
Key Features
- 4"and 5" aluminized steel construction for durability and strength
