Interested in a new exhaust system for your LML Duramax? Check out the Large Bore-HD down-pipe back dual exhaust system by aFe. This system is constructed from 4" mandrel-bent 409 stainless steel tubing and uses a 24"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" polished 304 stainless steel tips with laser-cut stainless steel aFe power badges. Large Bore-HD 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 Large Bore-HD exhaust system is constructed from 4" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.
This exhaust system uses a mitered merge collector to convert the standard single exhaust to an aggressive dual exhaust.
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.
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.
*This kit will only fit 2015 models manufactured before July 2014 equipped with a non-flanged down pipe.
