Aluminized Exhaust

The Dieselr Aluminized 4″,5" Cat Back Exhaust (2004.5–2007) is built for durability, precision fit, and smooth exhaust flow. Crafted from 4-inch , 5-inch heavy-gauge aluminized steel, this system reduces backpressure, stabilizes EGTs, and delivers consistent performance for high-load or daily-driven diesel builds.

Each Dieselr system is precision-welded and mandrel-bent to maintain uninterrupted flow from the catalyst outlet to the tail section. The aluminized coating protects against corrosion, heat, and road debris, ensuring long-term reliability in any environment.

Installation is straightforward with OEM-style hangers and clamps for a tight, vibration-free fit. The sound is refined and balanced — a clean tone that reflects true Dieselr engineering.

Key Features

  • 4″,5" aluminized steel construction for strength and corrosion resistance
  • Mandrel bends for optimized exhaust flow
  • Precision-welded seams for long-term durability
  • Factory-style fitment for easy installation

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.
