This unit uses all factory mounting locations and comes with a bolt-on bracket that supports the driverside tailpipe.

ATLAS exhaust systems are the perfect combination of performance, fit and value.
Single To Dual Exhaust Conversion:
This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust.
Fits With Spare Tire:
This exhaust system fits perfectly without relocating the spare tire.
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.
Flow and Performance:
This ATLAS exhaust system is constructed of 4" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.
Massive 6" Black Tips Option:
Finishing off the exhaust are dual powder-coated high temp black 304 stainless steel exhaust tips. The tips feature a drain port on the bottom to keep rust and corrosion away. Unique stainless steel laser-cut aFe Power logo plate are riveted on for an aggressive style.
Polished Tips Option:
Finishing off the exhaust are dual high luster, polished 304 stainless steel slash-cut tips. The tips feature a drain port on the bottom to keep rust and corrosion away.
