Aluminized Exhaust

The Dieselr Aluminized Downpipe Back Exhaust (2011–2015) is designed for serious diesel owners who want proven airflow gains and rugged dependability. Constructed from 4-inch, 5-inch heavy-gauge aluminized steel, this system provides a clean, unrestricted path from turbo outlet to tail section—improving exhaust velocity and lowering EGTs under heavy load.

Each Dieselr exhaust is mandrel-bent for precise geometry and TIG-welded for lasting strength. The aluminized coating resists corrosion, heat, and salt, ensuring long-term reliability in demanding conditions. Its OEM-style alignment and mounting points make installation simple, secure, and clean with no modifications required.

Built for performance and longevity, this system defines what Dieselr stands for—straightforward design, precision fitment, and real-world durability tested on working diesels.

Key Features

  • 4",5" aluminized steel for maximum strength and corrosion protection
  • Mandrel bends for smooth, consistent exhaust flow
  • Factory-style hanger fitment for simple, secure installation
  • Built to handle heat, load, and high-pressure applications

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.
