Product details
Interested in a new exhaust system for your LML Duramax? Check out the ATLAS dual DPF-Back exhaust system by aFe. This system is constructed from 4" mandrel-bent aluminized steel tubing and uses 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 driver side 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. 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 aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's. Polished Tips: Finishing off the exhaust are dual high luster, polished 304 stainless steel slash-cut tips. This tip features a laser-cut stainless steel aFe power badge for an aggressive style.
