Huge New Flowmaster Exhaust Sound with Improved Performance

While there are plenty of cat-back exhaust systems on the market that have either a dual-rear exit or dual-side exit design, none give you the option of choosing an exit configuration to meet your application or truck's styling. This Flowmaster American Thunder Cat-Back Kit (Aluminized) is the exception. This cleverly designed exhaust system comes with two sets of tailpipe tubing, allowing you to choose the look you want for your 4.6L or 5.4L Ford F150 (2004-2008). You get a unique, high-performance muffler design that gives your truck a deep, throaty growl. Built right here in the USA and backed by Flowmaster's legendary name, your truck will instantly get a huge boost in overall performance, superior exhaust gas flow, passing power, and plenty of Flowmaster sound.

Flowmaster's American Thunder exhaust systems produce a more Moderate Exterior Sound Level than other product line-ups they offer. Utilizing that classic muscle car sound that put Flowmaster on the map, the American Thunder Series features mufflers tuned to deliver more power, torque, throttle response and mileage. Best of all, these exhaust systems take quiet, power-lacking vehicles and turns them into great performers with a tone especially designed for muscle car and truck fans. American Thunder is the most authentic Flowmaster muffler they offer. If you're looking to get the most performance and turn some heads, this could be your best bet.

Bed/Cab Fitment:


Flowmaster's Cat-Back Kit comes with an extension pipe and inlet tube that need to be cut down for proper fitment on most cab/bed configurations. Call Stage 3 at 1-877-578-2433 for more information.

Easy Installation

The Flowmaster American Thunder Cat-Back Kit comes with all the installation hardware and instructions needed to make this a quick and easy installation (approximately 2 hours using standard tools). The system features a dual rear exit tip design with (2) 2.5" outlets that exit right under your truck's rear bumper to give this system a more unique look than stock. Despite the kit having a dual exit configuration, Flowmaster carefully designed it to bolt right on in place of stock. This kit hooks up to your truck's mid-pipe and comes with an extension pipe that allows this system to fit the (above mentioned) F150 wheelbase configuration. The mandrel-bent outlet tubes help minimize back pressure and restrictions on your truck. The tubes split at Flowmaster's specially-designed American Thunder muffler to keep overall volume fairly low while still giving your truck a nice, noticeable rumble.
