Awesome, Deep Exhaust Note

The stock exhaust note of the 2.7L and 3.5L EcoBoost V6 F150s isn't much to write home about, and the 5.0L V8's exhaust tone is outright disappointing. The good news is that our friends over at Flowmaster Exhaust are to help with their American Thunder Cat-Back Exhaust Kit for the 2015-2019 EcoBoost, 3.5L V6, and 5.0L V8 F150s. This kit has larger exhaust tubing than stock, an aggressive muffler design, and resonator delete that all work together to generate an absolutely ferocious and deep tone for your custom F150 build. The Flowmaster Cat-Back System even changes your 2015-2017 F150's exit configuration into your choice of dual straight out the rear exit or out the side exit with its two sets of exhaust tubing leading to the system's oversized tips. The kit is an excellent way to get just the sound, performance, and look you want out of your wicked 2015-2020 F150 build, all in a high-quality package that won't let you or your 2015-2020 F150 down in just about any application you have in mind.

409 Stainless Steel Exhaust Kit with your Choice of Tip Exit

The Flowmaster American Thunder Cat-Back Exhaust Kit offers up near-perfect fitment for almost all of the 2015-2017 F150 wheelbase sizes, and was designed from the ground up to give your truck an impressive, new sound. Flowmaster builds each of their American Thunder Kits around one of their Super 40 Series performance mufflers that utilize Flowmaster's unique Delta-Flow chambered internal design that gives your truck a deep rumble and aggressive new levels of sound volume while cancelling out a lot of the annoying high-pitched frequencies that cause rasp and drone. The muffler has a single 3" inlet that then splits into dual 2.5" outlet tubes. The outlet tubes are each mandrel-bent to ensure smooth exhaust outflow with minimal restrictions and come with modular tubing that lets you choose between a straight out the rear exit or dual rear side exit tip configuration to meet your styling needs or application. The kit is rounded out by a pair of aggressive 3" polished 304 stainless steel exhaust tips embossed with the Flowmaster logo. The rest of the kit is made out of 409 stainless steel and comes with installation hardware and instructions. Flowmaster backs each of their 409 stainless steel systems with a Limited Lifetime Warranty.
