Apollo GT Series 3 IN 409 Stainless Steel Cat-Back Exhaust System w/ Polish Tip GM Silverado/Sierra 1500 09-18 V6-4.3/V8-4.8/5.3L

aFe POWER introduces the Apollo GT Series cat-back dual rear exit exhaust system for the 2009-2018 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 4-1/2" diameter polished tips. The tips comes with a laser-cut aFe POWERbadge riveted on for an aggressive style.
