Low Grumbling Exhaust. Make sure everyone takes your truck seriously by equipping it with this Flowmaster American Thunder stainless steel cat-back exhaust kit. The whole system is a beautiful chrome color and it drops down your exhaust note lower and gives it more aggression. You'll be rumbling down the road and when you stomp on the gas you'll acclerate with a mighty roar thanks to the wide pipes and tip of this kit. It's amazing what an exhaust modification can do for the way your truck sounds, and you'll sound like a serious performance truck when this is on.

More Horses. Three-inch pipes work wonders for the efficiency of an exhaust system. This kit features wide pipes that let exhaust flow through faster. That means there will be less pressure on the system and that it will run more efficiently overall. From the moment that you begin driving you'll notice that your truck has a bit more pep. That's because both the horsepower and torque are increased by the kit overall. You'll be faster and more capable when you use these pipes.

Polished Stainless. You can count on this exhaust system to last through heavy use over the years. It's made from polished stainless steel and will hold up to moisture, mud, dirt and other debris just fine. Unlike the coated pipes, this one is made with stainless steel all the way through, so even scraps won't lead to corrosion over time. You'll enjoy a solid colored exhaust system that looks and functions the same for many years.

Stock Installation. The exhaust systems like this one that use the stock hangers go on the fastest. When you install this kit it will take just a few hours to bolt it into the stock exhaust hangers already mounted on your truck. It's simple to do and you'll be thrilled that you decided to go with this kit over some of the more difficult options avialable today.

Application. The Flowmaster American Thunder Stainless Steel Cat-Back System is designed to fit all 2009 to 2010 F-150s powered by the 4.6L engine.
