aFe Power Apollo GT Series 409 SS Cat-Back Exhaust System w/Polished Tip | 3" Pipe Diameter (09-18 Chevrolet/GMC Silverado/Sierra 1500 | Standard Cab | 4.3L V6/4.8L/5.3L V8)

aFe POWER introduces the Apollo GT Series cat-back dual rear exit exhaust system for the Chevrolet Silverado/GMC Sierra 1500 with V6-4.3L & V8-4.8L/5.3L engine. This dual 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 free-flow single-in dual out 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 are dual 4.5" diameter polished tips. The tips comes with a laser-cut aFe POWER badge riveted on for an aggressive style. Test Results: In testing, this 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). Installation is a Snap: This Apollo GT Series exhaust system includes an extension tube for regular cab/long beds and uses factory mounting locations providing stability and hassle-free installation. A bolt on hanger mount is used to support the driver side tube. Leak-Free Seal: High quality band clamps are used for a complete 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. 4.5" Dia. Polished Tip: Finishing off this system are dual 4.5" diameter, polished, stainless steel tips. The tips come with a laser-cut aFe POWER badge riveted on for an aggressive style.
