Unmistakable sound. The Flowmaster Force II Single Exhaust System with Polished Tip; Side Exit will be sure to give you the powerful sound you are looking for out of your Sierra. The muffler is sure to enhance your sound to just the right levels. The low rumble produced by this product is perfect for the person who wants more noise out of his or her exhaust system, but doesn't want to wake the entire neighborhood.
Increased power. The mandrel bent tubing of this system makes sure the air will flow through your new system and give you some extra power to your truck. The exit of the system behind the rear tire puts that power exactly where it should be. You'll experience more torque and control than ever before. With the new sound of your system and the added force behind the wheel you'll be sure to impress as you are driving down the roads.
Finished for strength. The Flowmaster Force II Cat-Back Exhaust is made to last. The materials used in this kit are specifically picked to make sure your system doesn't let up to any forces. The durable stainless steel tubing is strong and corrosion resistant. The muffler and stainless steel tips give you a great look plus a style that will last for miles. The impressive look of this system paired with the durability and quality of the Flowmaster Force will have you feeling like your truck is the most powerful on the roads. The system is also matched with a lifetime limited warranty.
Everything you need included. All the hardware you need to easily install your new system onto your truck comes right in the box. All you need is some basic hand tools, and the exhaust kit will install right to the factory settings already on your F-150. You won't need to make any modifications to your truck to get this system going, but you may have to cut down the pipe a little depending on the size of your cab and bed.
