AFE Power ATLAS DP-Back Aluminized Steel Exhaust System 4 in. Tubing Incl. 12 in. Muffler/2 pc. Tailpipe/Hangers/Clamps/6 in. Tips Race Only

Interested in a new exhaust system for your LML Duramax. Check out the ATLAS down-pipe back dual exhaust system by aFe. This system is constructed from 4" mandrel-bent aluminized steel tubing and uses a 12"L 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" 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's.

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

Finishing off the exhaust are 2 tips, either polished 304 stainless steel or black, slash-cut tips. The tips feature a drain port on the bottom to keep rust and corrosion away.

All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.

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.
