Aluminized Exhaust

The Dieselr Aluminized Downpipe Back Exhaust (2015.5–2016) is built for real-world performance and long-term reliability. Crafted from 4-inch, 5-inch heavy-gauge aluminized steel, this system delivers smoother exhaust flow, lower EGTs, and a bold, refined tone built for high-load conditions.

Each Dieselr exhaust is mandrel-bent to maintain unrestricted airflow and precision-welded for lasting strength. The aluminized coating resists corrosion, oxidation, and heat stress, making it ideal for harsh working environments and daily-driven diesel applications alike.

With factory-style hanger alignment and secure clamping points, installation is fast, clean, and reliable—built to fit right and last long. Dieselr aluminized systems are tested and tuned for flow, efficiency, and strength that never quits.

Key Features

  • 4",5" aluminized steel construction for maximum durability
  • Mandrel-bent tubing for consistent exhaust velocity
  • Factory-style fitment for straightforward installation
  • Corrosion-resistant finish for extended 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.
