      Delivers a Superb Exhaust System Performance. Enhance your Ford F-250 or F-350 Super Duty’s off-roading capabilities by installing AFE’s Large Bore-HD 4-Inch Down-Pipe Back Dual Exhaust System with Black Tips and Side Exit. Due to the system’s smooth transition bends, it has lower turbulence than your truck’s stock component. This allows the exhaust system to increase its exhaust volume, boost the vehicle’s torque and horsepower gains, as well as help lower its EGT.

      Made From Highly Durable Stainless Steel. The Large Bore-HD exhaust system by AFE boasts a 100% hand MIG-welded 4-inch mandrel-bent 409 stainless steel tubing construction. Thanks to its high-quality build, you can rest assured that it can endure the toughest off-road environments and climates.

      A 2-Hour Install. This exhaust system comes with OE-style bayonet hangers and utilizes all of your truck’s mounting locations. However, some cutting might be required, so the entire installation procedure will take 2 hours to complete.

      Application. The AFE Large Bore-HD 4-Inch Down-Pipe Back Dual Exhaust System with Black Tips and Side Exit is ideal for use with all 2017-2020 6.7L Ford F-250/F-350 Super Duty models.
