Product Details

The Flowmaster 817756 Outlaw Cat-Back Exhaust System delivers race-proven performance and an aggressive exhaust tone for 2015-2020 Ford F-150 trucks equipped with 2.7L, 3.3L, or 3.5L EcoBoost engines. This emissions-legal system is engineered for enthusiasts who demand maximum sound and performance from their truck.

Key Features:

  • Race-proven Outlaw Series muffler produces aggressive exterior roar and bold interior tone
  • Large 4.00-inch mandrel-bent tailpipe maximizes exhaust flow and performance
  • Single Out Side (SOS) configuration with side exit design
  • 409S stainless steel construction for durability and corrosion resistance
  • 5.00-inch black ceramic coated stainless steel Flowmaster embossed tip
  • Dyno-tuned design optimizes horsepower and torque output
  • Bolt-on installation uses factory hanger locations—no welding or cutting required
  • Complete hardware kit included for straightforward installation
  • Made in the USA and backed by Flowmaster's Lifetime Limited Warranty

This system fits all 2WD and 4WD configurations and wheelbase lengths, excluding Standard Cab/Short Bed and Ford Raptor models. The mandrel-bent tubing ensures smooth exhaust gas flow while reducing backpressure, resulting in improved throttle response and that unmistakable Flowmaster sound that sets your truck apart.
