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.

Key Features

  • Mandrel bends for smooth exhaust flow
  • OEM hanger fitment for easy installation
  • Corrosion-resistant coating for long service life

FAQs

Aluminized vs. stainless — which should I choose?
Aluminized offers excellent value and everyday durability; stainless maximizes corrosion resistance in harsh climates. Sound and flow are comparable in like-for-like systems.
Will this system drone?
Our bend geometry and muffler selections minimize cabin drone at highway speeds while preserving a confident diesel tone.
Is it truly bolt-on?
Yes—OE locations, contour-bent hangers, and Perfect Fit Lap Joint Exhaust Band clamps simplify install with hand tools. Remember to re-torque clamps after 100–150 miles.
