The aFe Large Bore-HD 5" 409-SS DPF-back exhaust with polished tip is made for 2017–2019 GM Duramax V8 6.6L (L5P) diesel trucks. It uses 5" mandrel-bent 409 stainless tubing, OE-style bayonet hangers and high-quality band clamps for leak-free sealing and factory mounting. A 6" polished intercooled slash-cut tip with vents helps reduce tailpipe temperatures while smooth bends promote improved flow and reduced turbulence.
