  • Model: FLO-817503
  • Manufactured by: FLOWMASTER

The Flowmaster Force II 817503 Axle-Back is 14 pounds lighter than the factory 2011-13 5.0L Mustang GT mufflers!

Looking to get increased performance from your red hot 5.0 Mustang? The Flowmaster 817503 Force II Axle-back system for the 2011-13 Ford Mustang GT with 5.0L engine ups the ante with increased horsepower, torque and mileage from these impressive machines. Intended for Mustang Owners looking for the performance benefits of a Flowmaster system, but with a quieter tone, the 817503 Force II axle back system features specially tuned mufflers that produce the Flowmaster signature sound, providing a deep exterior sound level while maintaining a mild sound level inside the car.

The system is constructed with 409S stainless steel for maximum durability and includes cool 4.00-inch diameter polished tips with embossed logo that exit through the factory rear valence cutouts. The kit is a true bolt-on and includes everything needed to easily install at home with basic hand tools.

Manufactured in the USA, the system is backed by the Flowmaster Limited Lifetime Warranty.
