About the manufacturer
aFe POWER is proud to introduce the Apollo GT Series dual rear exit cat-back exhaust system for the 2014-2019 GM Silverado/Sierra 1500 with V6-4.3L/V8-5.3L engines. This cat-back exhaust system is constructed out of 3 IN 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 IN single-in dual out muffler is included which improves performance 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 rear 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, dual 4-1/2" polished 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.
This Apollo GT Series exhaust system uses all factory mounting locations and is supplied with all necessary hardware including OE style hangers for the perfect fit and finish. A free-flowing stainless steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig. 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. High quality OE-style flange and band clamps are used for a complete 360-degree sealing surface eliminating leak paths. This exhaust system fits perfectly without removing the spare tire. This exhaust system is constructed of 3 IN mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and improving throttle response. Finishing off the exhaust are dual polished stainless steel exhaust tips. The tips feature unique stainless steel laser-cut aFe POWER logo plates which are riveted on for an aggressive style.
