Flowmaster Force II For Milder Exhaust Tone

While a cat-back exhaust can pull a bunch of extra power out of your (2011-2014) F150 EcoBoost's 3.5L V6, there's very few that sound great while keeping drone and that turbo whine down to a minimum. The Flowmaster Force II Cat-Back Exhaust Kit (Stainless Steel) uses a unique muffler combined with highly efficient tubing to give your engine extra horsepower, more torque and improved fuel economy; all of this performance and a great, deep sound with minimal drone and shriek to allow your truck to turn its power up to 11 without the volume. Built right here in the USA and backed by Flowmaster's legendary name, your truck will instantly get a nice bump in overall performance on top of a great sound that's not too overpowering.

Stainless Steel Construction with Excellent Fit and Finish

Flowmaster's Force II exhaust systems offer a more Moderate Exterior Sound Level, than other product line-ups they offer, which frees up stock restrictions on your system and allows for wicked performance, all of this with an upgraded tone that lets your Ecoboost rumble and growl when you step on the gas. The Force II System incorporates large displacement mufflers and resonators to control overall sound and increase the performance impression, including more horsepower, torque, and improved fuel economy. This is a great, well-rounded, option if you're looking to get the most out of your truck and gain a custom look.

Designed for Easy Install

The Flowmaster Force II 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 EcoBoost's 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 Force-II muffler to keep overall volume fairly low while still giving your truck a nice, noticeable rumble.
