The aFe MACH Force XP downpipe is a 100% TIG-welded, stepped-design down pipe that increases exhaust velocity and reduces low-pressure drops to aid scavenging and intake charge. It includes a resonance chamber to limit in-cab resonance and ships with required hardware and brackets for installation. Constructed from 409 stainless steel with CNC-machined flanges and high-temp ceramic coating options, explicit fitment covers GM diesel trucks (2004–2010) 6.6L LLY/LBZ/LMM.
