Aluminized Exhaust

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
  • Mandrel-bent design for smooth, efficient exhaust flow
  • OEM hanger fitment for simple, secure installation
  • Proven corrosion protection in demanding environments

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.
