Interested in a new exhaust system for your LML Duramax? Check out the Atlas downpipe back dual exhaust system by aFe. This system is constructed from 4" mandrel-bent aluminized steel tubing and uses a 12" long muffler, high quality band clamps and OE-style bayonet hangers. This unit uses all factory mounting locations and comes with a bolt-on bracket that supports the driverside tailpipe. This provides for a quick, hassle-free installation with no modification necessary.  Also included in this exhaust system are dual massive 6" high temp black powder-coated stainless steel tips with laser-cut stainless steel aFe power badges. 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.

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

Massive 6" Black Tips:
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:
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.

Note: This system is not legal for street use and cannot be installed in a California registered vehicle, nor can this system be sold legally in California.
