Flowmaster 718170 Details


This FlowFX cat-back exhaust system is for the 2021-2024 Ford F-150 trucks with the standard 2.7, 3.5, and 5.0-liter and PowerBoost 3.5L engines that are equipped with the optional dual exhaust out the rear bumper. This exhaust offers a deep throaty exhaust note with aggressive to moderate sound levels both inside and outside of the truck, with all the performance benefits that you would expect from Flowmaster. This bolt-on emissions-legal system features all mandrel-bent 409 stainless steel 3.00-inch tubing that flows into a FFX straight through muffler and exiting into large 3.00-inch dual tailpipes for maximum sound and performance. The system exits the OEM rear bumper cut outs and uses all the factory hanger locations. The tailpipes are finished off with a pair of large 4.50-inch black ceramic-coated stainless-steel tips for a more aggressive look than the factory tip. This exhaust system is covered by our Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation.
