Description
Up the Aggression. The AFE Large Bore-HD 3-Inch DPF-Back Single Exhaust System with Black Tip; Side Exit is the exhaust system you want if you’re looking to give your Sierra 1500 a more aggressive sound. More to the point, this DPF-back exhaust is engineered to transform your stock sound into a bass-rich growl that’s as fierce as your truck’s new style. Best of all, this exhaust delivers its new sound without greatly increasing its volume, so you don’t have to be too concerned about the neighbors.
Increased Exhaust Gas Velocity and Performance. This AFE DPF-back exhaust system features virtually straight-through exhaust plumbing designed to increase exhaust gas velocity. In doing so, this exhaust allows your engine to “breathe” better, giving you increases in power and torque. The result is your truck gets the performance to match its new aggressive sound.
Durable Build Quality. The DPF-back exhaust system is constructed from 409 stainless steel tubes measuring 3 inches in diameter for outstanding durability and corrosion resistance. Additionally, these stainless steel tubes are CNC mandrel-bent, ensuring a turbulence-free inner structure before being MIG-welded for added rigidity. Lastly, this exhaust is equipped with a 4.50-inch diameter slant-cut exhaust tip that’s powder-coated in black for rugged good looks.
Straightforward Install Procedure. This AFE DPF-back single-side exit exhaust system is designed to install into your truck’s factory exhaust’s location. No modifications to your vehicle are necessary. Moreover, installation requires just standard hand tools to complete and all necessary hardware is included.
Application. The AFE Large Bore-HD 3-Inch DPF-Back Single Exhaust System with Black Tip; Side Exit fits all 2020 to 2025 3.0L Duramax Chevrolet Sierra 1500 models.
