Aluminized Race Pipe

The Dieselr Aluminized 4" Cat & DPF Race Pipes (2011–2015) are engineered for serious diesel applications demanding reliability, flow efficiency, and long-term strength. Constructed from heavy-gauge aluminized steel, these pipes deliver clean airflow, reduced restriction, and dependable corrosion protection.

Every Dieselr race pipe is mandrel-bent for consistent exhaust velocity and precision-welded for a leak-free finish. The aluminized surface shields against heat, salt, and oxidation, ensuring the system holds up in harsh conditions and high-load use.

Installation is straightforward with factory-style hanger alignment and secure clamping points, giving a tight, professional fit without rattles or stress points.

Key Features

  • 4" aluminized steel for strength and corrosion resistance
  • Mandrel-bent tubing for unrestricted exhaust flow
  • Precision-welded seams for long-term reliability
  • Engineered for efficient installation and clean fitment

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.
