The AFE 49-04044 ATLAS 4" Dual Downpipe-Back Exhaust System is constructed from 4" mandrel-bent aluminized steel. This exhaust system will provide a mild, throaty tone with a 12" long muffler and installs easily with high-quality band clamps and OE-style bayonet hangers. Designed for ease of install, this exhaust system will reinstall using the factory mounting locations and comes complete with a bolt-on bracket that supports the driver side tailpipe. The finishing touch is your choice of a polished or powdercoated  exhaust tip. 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 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.

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.

Merge Collector:
This exhaust system uses a mitered merge collector to convert the standard single exhaust to an aggressive dual exhaust.
