Boost Performance and Sound. Get improved mileage, power and throttle response for your Ford F-150 Lightning truck, and have the added convenience of keeping the factory catalytic converter by installing a Flowmaster American Thunder Cat-Back Exhaust — Middle Side Exit. Not only will this cat-back exhaust increase torque and horsepower, it will add a deep and aggressive rumble that will make you feel as if you're about to hit the NASCAR race track.

Moderate to Aggressive Exterior Exhaust Tone. The Flowmaster American Thunder Cat-Back Exhaust — Middle Side Exit delivers a moderate to aggressive tone that can be appreciated on both the interior and exterior, and is best suited for the Ford-150 enthusiast that wants their presence to be known when off-roading, or on daily rides on the street.

Retains Factory Cats. Flowmaster designed their middle side exit exhaust to be easily installed with the clamps provided in the parts kit; easily sliding them onto the inlet pipes. The muffler assembly will then be placed onto the back of the catalytic converter. Because the factory catalytic converter does not have to be removed, this replacement upgrade will keep your F-150 smog-legal.

Stainless Steel Construction. Flowmaster manufactures and designs their cat-back exhaust from mandrel-bent, 16-gauge, 2-1/2-inch aluminized stainless steel tubing made for added durability and corrosion resistance. This Flowmaster American Thunder Cat-Back Exhaust features a middle side exit for superb exhaust flow.

Application. This Flowmaster American Thunder Cat-Back Exhaust — Middle Side Exit is designed to fit 1999-2003 Ford F-150 Lightning models.
