Description
Description
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
