Flowmaster American Thunder Dual Exhaust System; Side/Rear Exit (09-10 5.4L F-150, Excluding Raptor)

Make Your Truck Roar. Roar down the road with the sounds of raw power thanks to this Flowmaster American Thunder stainless steel cat-back exhaust. It's optimized to put out a rumbling aggressive noise every time that you drive, and you'll be thrilled to show off your new kit the next time that you go for a drive. Your truck will sound larger and more powerful because this exhaust kit uses wide 3" piping and tips, and features a specially designed muffler for the best acoustics.

Serious Torque. You won't believe how much faster your truck feels after you install this Flowmaster American Thunder stainless steel cat-back exhaust system. The kit goes on easily, but it literally transforms the way that exhaust exits out of your vehicle. Instead of taking the cramped and high pressure path to the outside world, the new system creates a smooth flowing and constant path through mandrel-bent tubes that won't kink or minimize air flow. The result is that your engine can run more effectively than ever before, and you'll see horsepower and torque improvements as soon as this kit is put into position.

409 Stainless. All the pipes, the muffler and the tip of this exhaust system are made from thick and reliable 409 stainless steel. The overall kit is designed to withstand corrosion, heavy use and tough situations that would make a standard exhaust fail over time. That's why this system is made to work for years without issues, and why you can count on it to keep running long after you would have replaced a standard exhaust pipe.

Simple Installation Steps. Follow along with the basic installation steps and you can go from having a basic exhaust system to getting this one installed on your truck. Just remove the old parts and use the OEM hangers to lock in your new ones. You will have all the hardware that you need to do the job and it won't take much time at all to go from start to finish. Around two hours is all you need to get your new exhaust system installed and ready to go. Some cutting may be required to get the pipes to fit properly depending on the bed style your truck has.
