The MACH Force XP cat-back exhaust for GM diesel trucks (2001–2005 6.6L LB7/LLY) is made from mandrel-bent 4" 409 stainless steel to increase flow, horsepower and torque while lowering EGTs. Factory mounting locations and OE-style band clamps ensure a secure fit; a free-flowing muffler smooths high tones and helps unleash available power with reliable, long-term performance.
