AFE MachForce XP 4-Inch DPF-Back Exhaust System for 2007–2010 GM 6.6L LMM Duramax Diesel Trucks

Description

This exhaust system replaces the restrictive factory routing with a mandrel-bent DPF-back design engineered for high-flow performance on 6.6L LMM diesel GM trucks. Constructed from 4 in. 409 stainless steel tubing and matched to a 24 in. free-flowing muffler, the assembly reduces EGTs while increasing horsepower and torque. OE-style flanges, band clamps, and bayonet hangers use factory mounting locations for a secure, bolt-on installation with 360° sealing and long-term durability under high heat and vibration.
