The MACH Force XP cat-back exhaust for GM diesel trucks (2006–2007 6.6L LLY/LBZ) is crafted from mandrel-bent 4" 409 stainless steel to enhance flow and reduce EGTs, delivering increased horsepower and torque. OE-style band clamps, factory mounting points and a polished tip make installation straightforward, while a free-flowing muffler refines sound and performance for dependable street use.
