aFe POWER - Large Bore-HD 4in 409 SS DPF-Back w/Dual Polished Tips
Description
Interested in a new for your L5P Duramax? Check out the Large Bore-HD dual DPF-Back by aFe. This system is constructed from 4" mandrel-bent 409 stainless 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 are dual massive 6" high temp black powder-coated stainless steel tips with a laser-cut stainless steel aFe power badges. Large Bore-HDs 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 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 Large Bore-HD 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. 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
