Sound boost. You’ll get an unmistakable Flowmaster sound after installing this kit onto your F-150. The Force II Cat-Master Exhaust system will give you a mild low sound that is perfect for the classic upgrade. You’ll get a moderate growl that will make you feel like you are driving an entirely different truck. The feel and noise you’ll get out of your new system will be sure to impress you and anyone else who hears it.

Polished power. The noise isn’t all you’ll get out of this great Flowmaster Force II Cat-Back Exhaust system with a single side exit. The way the tubes are bent on this system are meant to give you more power than you thought would be possible. The free flowing system give the air the path to get where it needs to be and give you the power you deserve. You’ll get added torque and performance out of the system.

Durable construction. Designed with everything in mind, the Flowmaster Force II is made of only the most durable materials. Stainless steel tubing will give strength to this kit and has corrosion resistant properties that will ensure you ever have to replace or fix it. The 70 series muffler is complimented by a huge 4 inch diameter polished stainless steel tip. All of this gives you a stylish and strong look to go with your powerful new sound.

Direct upgrade means easy installation. This entire system was made to be a complete replacement to your current factory exhaust system. All you have to do is grab some simple hand tools and get to work. No modifications to your truck will be necessary, but you might need to cut down the piping a little depending on the size of your truck cab and bed.

can you replace the stainless polished tip for the black tip on other flowmaster exhaust kits?

Anonymous

  • You will be able to replace the polished tip for the black one from the Outlaw cat-back as the tips will both be 4" in size. With that being said, Flowmaster does not offer the Force II with a black tip.

    I selected Flowmaster because of their reputation. Installer said the kit fit well and took less than an hour in a pro muffler shop. I can now hear my truck run, but it's not as loud as the Heartthrob exhaust on my '11 F150. I'm happy.

    Review from Flowmaster Force II Cat-Back Exhaust - Single Side Exit (15-18 5.0L)

    Gotta love the sound

    It is worth the price just for the sound. The key to my purchase was sound...NOT too Loud! The stock muffler with the factory resonator just sounded weak...not anymore. As for performance gains, I can't verify with dyno numbers but it does pull harder. If you get this exhaust don't forget a great intake and a programmer to round things out! I highly recommend this exhaust and the sound it makes. If you want really loud then choose another flowmaster system. Will not make the neighbors crazy! Very happy I ordered through American Muscle.
