    Make Your Truck Roar. Drive with a vengeance and let everyone know you're coming with the Flowmaster Force II dual cat-back system equipped. It puts out a deep rumble that stands out among all the other F-150 trucks. You'll sound more sinister, you'll be more formidable and you'll enjoy driving around just to drive with this kit attached. It sounds so good that your truck will feel more powerful and will sound like a new vehicle entirely.

    Serious Performance Enhancer. Extend your truck's power band just a bit further with this Flowmaster Force II dual cat-back system. It's designed with wide stainless steel pipes and a dual exhaust for either the side or rear of your truck to optimize exhaust flow as much as possible. When using this kit you'll improve your efficiency dramatically and give your truck more power to work wtih. You'll love the torque that you get from this exhaust system, and it's a simple modification too.

    Weather Protected. Exhaust systems are exposed to the elements. This one is designed to stand up to harsh weather conditions without an issue. You can drive around confidently without worrying about rust to the system because it's made from stainless steel. Even if the pipes and muffler are coated with salt and water, you won't develop rust immediately. Stainless steel stands up to corrosion well, which is why stainless is used for water-based applications. For the toughest exhaust system look into something like the Flowmaster Force II dual cat-back kit that is made of stainless.

    A Fast Installation. With just three or four hours this Flowmaster Force II dual cat-back system will go under your truck and lock firmly into position. To go through the installation just add the included hangers to your truck and then mount the pipes ot the hangers. That's the whole process. You can have the work done professionally for best results, or tackle the project yourself with good results as well.

    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 including Super Crew Cab.

      Flomaster 50 series

      Sounds great! Very timid with deep rumble when at idle and daily driving but really screams when you stomp the pedal. Especially when paired with shorty headers and if you you really want to open up the exhaust then cut the cats!

      Getting a new one

      So this set up is great. I already have it on my daily driver and now that I have my jacked up f-150 I am putting it on this one as well.
