Product Details

The Flowmaster Force II Cat-Back Exhaust System delivers enhanced performance and a refined exhaust note for your vehicle. This complete bolt-on system features Flowmaster's Super 40 Series performance muffler, engineered to provide a moderate to mild sound level while maximizing exhaust flow for improved horsepower and torque.

Performance Benefits:

  • Maximum dyno-tested gains of 6 horsepower and 7 lb-ft of torque at the wheels
  • 3.00-inch mandrel-bent tubing maintains optimal exhaust velocity and flow
  • Super 40 Series muffler uses Flowmaster's original two-chamber design for aggressive sound without drone
  • Tuned resonator eliminates unwanted interior drone for comfortable highway cruising

Quality Construction:

  • 409 stainless steel construction throughout for superior durability and corrosion resistance
  • 16-gauge mandrel-bent stainless steel tubing ensures consistent diameter for maximum flow
  • 3.50-inch polished stainless steel tip adds a custom finishing touch

Installation:

  • Direct bolt-on design uses factory hanger locations for straightforward installation
  • Includes all necessary hardware for complete at-home installation
  • No cutting or welding required

This cat-back system is an excellent choice for enthusiasts seeking noticeable performance gains with a refined exhaust tone that won't overwhelm the cabin during daily driving.
