      Menacing Sound. If your Duramax-equipped Silverado 1500’s stock exhaust sound doesn’t quite do it for you then you need the AFE Large Bore-HD 3-Inch DPF-Back Single Exhaust System with Polished Tip; Side Exit. This DPF-back features an almost straight-through design and a large-bore construction. Combined, this exhaust gives your truck a menacing bass-rich growl that’s sure to put a smile on your face. What’s more, this exhaust produces its new sound without overly raising its volume so you don’t have to worry about disturbing your neighbors.

      Enhanced Exhaust Gas Velocity and Performance. This AFE DPF-back exhaust system’s nearly straight-through plumbing will also encourage faster exhaust gas velocity. This factor enables your engine to go through its combustion cycle much more efficiently. This way, you have the power to match your new sound.

      Rugged Build Quality. The DPF-back exhaust system is constructed from high-grade 3-inch diameter 409 stainless steel tubes for strength and corrosion resistance. Furthermore, this exhaust system is fully mandrel-bent and MIG-welded for rigidity and a free-flowing inner structure. Rounding out its construction is a 4.50-inch diameter slant-cut and polished exhaust tip machine formed from 304 stainless steel, giving the assembly a classy style.

      Practical Install Procedure. Installing this AFE DPF-back single-side exit exhaust system is a fairly practical process as it will install into your truck’s factory exhaust location without the need for modifications. Also, installation is completed using standard hand tools and the included hardware.

      Application. The AFE Large Bore-HD 3-Inch DPF-Back Single Exhaust System with Polished Tip; Side Exit fits all 2020 to 2022 3.0L Duramax Chevrolet Silverado 1500 models.
