Cat-Back Exhaust

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). 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. High quality band clamps are used for a complete 360-degree sealing surface eliminating leak paths. 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. 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. Finishing off this system are dual 4-1/2" diameter, polished, stainless steel tips. The tips come with a laser-cut aFe POWER badge riveted on for an aggressive style. Regular Cab / Short Bed 6.6 Ft. (119" Wheelbase)
