aFe POWER introduces the MACH Force-Xp cat-back exhaust system for the 2009-2019 GM Silverado/Sierra 1500 with V6-4.3L & V8-4.8L/5.3L engine. This exhaust system is constructed out of 3" 100% MIG-welded, mandrel-bent, stainless steel tubing for maximum flow. The smooth transition bends allow for low turbulence, increasing horsepower, torque and improved throttle response. A strait thru free-flow muffler is included which improves performance across the power band while maintaining an awesome sound. In testing, the cat-back exhaust system resulted in gains up to + 14 horsepower and + 17 lbs. x ft. of torque, as measured on our in-house dyno (tested on 2014 Chevrolet Silverado V8-5.3L). Finishing off this exhaust is a 4-1/2" diameter black tip. The tip comes with a laser-cut aFe POWER badge riveted on for an aggressive style. Installation is a Snap: This MACH Force-XP exhaust system includes an extension tube for regular cab/long beds and uses factory mounting locations providing stability and hassle-free installation. Leak-Free Seal: High quality band clamps are used for a complet49-44072-Be 360-degree sealing surface eliminating leak paths. Aggressive Sound: A straight-through designed, free-flowing stainless steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque. Perfect Fit: OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time. This makes for an easy installation with no cutting required. 4-1/2" Dia.
