Most people think getting more horses under their hood comes at the cost of the neighbors' peace and quiet. But with the Flowmaster Force II Exhaust System, you can enjoy a big boost in power without a lot of extra noise. Flowmaster's engineers have discovered a way to increase your horsepower and performance without making your vehicle louder.

When compared to the American Thunder system, the Flowmaster Force II Exhaust System boosts power without so much obnoxious cruising noise. Once installed, this exhaust system adds a 5-10% acceleration gain, and up to 2 MPG in fuel economy right out of the gate. The Force II offers the same pedal feel as the American Thunder system, and at lower altitudes,  while the sound is noticeably quieter and more muffled. The Flowmaster muffler, with its chambered design, is responsible for its distinctive sound.

In addition to the necessary hardware, this kit comes with straightforward step-by-step installation instructions that allow you to complete the setup of the majority of systems in under an hour. Your system comes with a 3-Year Warranty from Flowmaster, Inc.

It’s a quality product with good installation instructions. I think they should add the torque specifications for the U-bolt brackets. I would recommend it to friends, and I would buy it again for another vehicle.

After six hours and the purchase of multiple tools to help expand the pipe, exhausting attempts at bending, and crying shifting and twisting… I finally gave up. Nothing seemed to fit, despite repeated attempts. Finally took it to a muffler shop, and even they gave up after 30 minutes and instead cut the pipe up and re-welded it. Should have gone with the bolt-on AFE or Borla. The muffler shop said they were surprised usually Flowmaster has better quality products.
