Cat-Back Exhaust

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. An included bolt-on bracket supports the driver's side tailpipe. A 21 IN 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 black stainless steel exhaust tips. The tips feature unique stainless steel laser-cut aFe POWER logo plates which are riveted on for an aggressive style.
