aFe is proud to introduce the MACH Force-Xp dual side-exit cat-back exhaust system for the 2014-2017 GM Silverado/Sierra 1500 with V6-4.3L/V8-5.3L engines. This cat-back 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 improving throttle response. In testing, this system resulted in gains up to +14 horsepower and +17 lbs. x ft. of torque verified by our in house dyno (vehicle tested with 5.3L engine). A hi-flow 21” single-in dual out muffler is included which improves performance across the power band while maintaining an awesome sound. This unit uses all factory mounting locations and comes with a bolt-on bracket that supports the driver side tailpipe. The aFe power dual side exit exhaust system was designed to retain the spare tire and includes high quality band clamps and OE-style bayonet hangers. This makes for an easy installation with no cutting required. To finish off the exhaust, are massive dual 4-1/2" black stainless steel tips with a laser-cut stainless steel aFe power badges for an aggressive style. This kit retains your spare tire and includes high quality band clamps and OE-style bayonet hangers for a hassle-free installation.Installation is a Snap:
