Aluminized Race Pipe

The Dieselr Aluminized 4" Cat Back Race Pipe (2007.5–2010 6.6L Duramax LMM) is built specifically for GM 2500/3500 Cab & Chassis trucks that demand performance, durability, and a perfect fit. Constructed from 4-inch heavy-duty aluminized steel, this system improves exhaust flow, lowers EGTs, and delivers a deep, confident tone built for real-world diesel work.

Every Dieselr system is mandrel-bent for smooth, unrestricted flow and precision-welded to ensure a tight, leak-free seal. The aluminized coating protects against corrosion and high-heat fatigue, keeping your exhaust performing and looking solid even after years on the road. Installation is straightforward, using OEM-style hangers for a clean, bolt-on fit.

Designed and tested on actual Duramax LMM Cab & Chassis platforms, this race pipe provides genuine performance gains—no gimmicks, just proven flow and strength built from steel.

Key Features

  • 4" aluminized steel construction for strength and corrosion resistance
  • Mandrel-bent tubing for efficient, consistent flow
  • OEM-hanger fitment for easy installation
  • Tested on 6.6L Duramax Cab & Chassis for verified performance

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.
