Aesthetics and function. That’s what you get with aFe’s Large Bore-HD 4” 409 Stainless Steel DPF-Back Exhaust system for your GM Duramax. 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 driverside tailpipe. This provides for a quick, hassle-free installation with no modification necessary. Also included in this exhaust system is dual massive 6" high temp black powder-coated 304 stainless steel tips with a laser-cut stainless steel aFe power badges. Large Bore-HD exhaust systems are the perfect combination of performance, fit and value. Not only that, you get the choice of either massive black tips, or massive polished tips.

Single To Dual Exhaust Conversion:

This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust.

Simple Installation:

All systems use factory mounting locations providing stability and hassle-free installation.

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 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.

OPTIONS:
  • 6” Massive Polished Tips: 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.

solid, quality cabinet and the best wall mounting system I have seen in a while
Color: Black With Silver Handle, Size: 24x30
It is a quality cabinet and has the best wall mounting system I have seen in a long time. The cabinet is solid and sturdy and was easy to put together. I can already see it lasting a long time in our bathroom. It is a bit heavy and you may need a second person to assist with mounting.

Looks great.
Love the look. Took a bit to put it together. The only negative was putting on the back with the tack nails. There was no way to see if you were hitting the board so I missed it about 1/3 of the time. Might be better to use wood glue and forget using the nails.

Perfect for a small bathroom
Nice cabinet for the bathroom. I have a 120-year-old house with small bathrooms; this doubled the cabinet space; the white keeps the room visually larger. I'd like to add the instructions are awesome: no verbiage just step by step diagrams. Each hole drilled and ready, as well as pilot hole where the screws will be received. Each piece labeled. The instructions have in the listings the count of pieces with a notation of extra screws, so you don't think you "screwed up" when you're done. One note: as the shelves are part of the construction, they are not adjustable, in my case not a big deal.
