    Thundering Performance. Thunder through town in your pickup with a loud resounding exhaust note that's impossible to ignore using this quality exhaust kit. The Flowmaster American Thunder dual rear cat-back exhaust system uses wide pipes and dual tailpipes along with a custom muffler to deliver the best sounds that you can get for a tough pickup. Add it onto your truck and you'll be drawing looks wherever you are.

    Maximize Your Power. This Flowmaster American Thunder dual rear cat-back exhaust system maximizes your truck engine performance. It won't take your truck to over the top performance levels, but will give you a bit more horsepower and even some added torque. This is possible because your engine will run more efficiently with some help from this kit. Add it to your truck and you'll immediately have performance that you're impressed by. This happens thanks to wider pipes and a more clever exhaust pathway than the standard system that comes with your pickup.

    It's Stainless Steel. Stainless steel is the material that the top exhaust systems are made from today. That's why this kit is made from the material. It will hold its own against corrosion so you can avoid replacing a rusted out kit in just a couple years. Sure your exhaust won't last forever, but when you invest in quality components like the ones on this kit you get something a bit more reliable at least. That's worth the money.

    Few Hour Installation. This exhaust kit won't go on instantly, but only takes a couple hours from start to finish. The longest bit of the process is attaching the different hangers up for the kit, but once that's done you can just like the parts on and fit them to the existing exhaust components to make it all work properly. With your new kit installed in just a few hours you will be ready to make the most of what it has to offer.

    Application. Fits 2004 to 2008 Ford F-150 and Lincoln Mark LT trucks with a 4.6L or 5.4L engine and all wheelbases, fits 2 and 4 wheel drive.
