Description
The Dieselr Aluminized 3″ Turbo Back Exhaust Single (2016–2021 2.8L LWN Duramax) is designed for GM Colorado and Canyon owners who want real performance, clean fitment, and lasting durability. Built from 3-inch heavy-duty aluminized steel, this system improves exhaust flow, reduces EGTs, and delivers a deep, consistent tone without compromising reliability.
Each Dieselr system is mandrel-bent for unrestricted flow and precision-welded for a tight, leak-free seal. The aluminized coating resists rust, heat, and road salt—perfect for daily drivers, tow rigs, and off-road builds alike. Installation is simple with OEM hanger alignment, ensuring a clean, secure fit that lasts.
Tested on real Duramax trucks, this turbo-back system is built the Dieselr way: no gimmicks, just proven performance and strength you can depend on.
