Upgrade your 2015–2020 Ford F-150 with the Flowmaster® American Thunder Cat-Back Exhaust System. Designed for trucks with 2.7L/3.3L/3.5L Ecoboost, 3.5L TiVCT, or 5.0L engines, this bolt-on 409S stainless steel system delivers an aggressive exterior tone while keeping interior sound moderate. Features include a 3.00-inch mandrel-bent inlet tube flowing into a Super 40 Series performance muffler, dual 2.50-inch mandrel-bent tailpipes, and polished 3.50-inch stainless steel tips. The system offers two tailpipe exit options—rear exit for a muscular look or side exit for towing RVs, boats, or trailers. Installation is easy using factory hanger locations, with all hardware included. Backed by Flowmaster’s Lifetime Limited Warranty.
