Enhance the power, tone, and durability of your Ford F-150 with the Flowmaster Signature Series Cat-Back Exhaust System. Engineered for 2015–2020 F-150 models equipped with the 2.7L EcoBoost, 3.5L EcoBoost, 3.5L Ti-VCT, and 5.0L engines, this premium system delivers a superior combination of performance and sound.

Constructed from brushed 304 stainless steel, the system offers maximum corrosion resistance and a clean, high-end appearance. The 3.00-inch mandrel-bent tube connects to a TIG-welded Signature Series straight-through muffler, providing a deep, powerful exhaust tone with a moderate interior sound level. The exhaust exits behind the passenger-side rear tire through a large 4.50-inch PVD-coated black chrome tip adorned with the Flowmaster logo.

This system uses factory hanger locations for a straightforward installation and includes all hardware and instructions. Dyno testing shows gains of up to 20 horsepower and 22 lb-ft of torque at the rear wheels, giving your F-150 a noticeable boost in performance.
