Make Your Truck Growl. Growl down the road in your pickup with a bit of help from this Flowmaster 409S Dual Rear cat-back system. It's been carefully engineered for the peak level of performance out of your truck. With some help from the kit you'll have a loud resounding exhaust note that isn't overwhelming, but is certainly powerful. That's exactly what you want for the top performance and for power that you can be proud of.

Faster Driving. When you slap this Flowmaster 409S Dual Rear cat-back system onto the bottom of your truck you'll move faster. The pipes make your engine more efficient, which means you get more horsepower and torque for the same gas. Not only that, but this system of large tubes and dual exhaust pipes will help make your truck more exciting to drive around. With just a short amount of time spent with the kit, you'll know that you don't want to go back to the stock pipes.

Built for Durability. Durability is the name of the game for exhaust systems. This one uses 16 gauge stainless steel and is made to last while down near the elements over time. You can count on your exhuast to hold up over time because it will resist corrosion much better than standard steel.

Straightforward Install. Installation takes a few hours from start to finish with this Flowmaster 409S Dual Rear cat-back system. That's because the installer must put on hangers and the hardware to hold all the parts in position before they are usable. These two steps take a bit of time and some experience, but they aren't too difficult and don't require special tools. It's something you could do at home, but we recommend using professional services instead.

Application. Fits 1998 to 2003 Ford F-150 truck on a 1/2 Ton chassis with a 4.6L or 5.4L engine, fits 2 and 4 wheel drive models and all wheelbases.
