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.

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.

O.E quality

Very impressed with the quality. Usually cheaper aftermarket filters are thin and flimsy. This is very durable and much better than what came out of my car. Fit my Odyssey perfectly.

A reliable purchase doing exactly what I expected
Item Package Quantity: 1
Look, you know how it is – what’s a game-changer for one person is just another Tuesday for another. For me, this Puroma Cabin Air Filter with Activated Carbon landed exactly where most good products do: solid and dependable. It arrived precisely as described, the activated carbon element is there, and it installed without a hitch in my vehicle. The air quality inside definitely feels cleaner, and it's doing its job filtering out the usual suspects. Does it redefine the very concept of cabin air filtration or deliver some earth-shattering innovation? Nah, not really. It’s a well-made, effective replacement that perfectly fulfills its purpose without any fuss or unexpected brilliance. A reliable purchase doing exactly what I expected. A firm 4 stars.
