Designed specifically for 2.7L, 3.5L, and 5.0L non-PowerBoost engines equipped with factory dual tailpipes, this direct-fit exhaust upgrade replaces the factory muffler and over-axle pipes while reusing the original tailpipes and exhaust tips. The Flow FX Series muffler delivers an aggressive to moderate exhaust tone with improved airflow characteristics, giving the truck a deeper, more powerful sound while maintaining a clean factory-style appearance. Constructed from durable 409 stainless steel with 3.00-inch mandrel-bent tubing, this system is engineered for long-lasting performance, increased exhaust flow, and an easy installation using factory hanger locations. Flowmaster testing has shown gains of up to 18 horsepower and 14 ft.-lbs. of torque at the rear wheels. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for 2021-2026 Ford F-150 trucks with 2.7L, 3.5L, and 5.0L non-PowerBoost engines with factory dual tailpipes.\u003c\/li\u003e\n\u003cli\u003eFlowmaster Flow FX Series muffler provides an aggressive to moderate exhaust sound with a deep performance tone.\u003c\/li\u003e\n\u003cli\u003e3.00-inch mandrel-bent exhaust tubing promotes improved exhaust gas flow and performance.\u003c\/li\u003e\n\u003cli\u003eManufactured from durable 409 stainless steel for excellent corrosion resistance and long service life.\u003c\/li\u003e\n\u003cli\u003eDirect-fit design replaces the factory muffler and over-axle pipes while reusing factory dual tailpipes and tips.\u003c\/li\u003e\n\u003cli\u003eUses factory hanger locations for a simplified installation process.\u003c\/li\u003e\n\u003cli\u003eDyno-tested performance improvements of up to 18 horsepower and 14 ft.-lbs. of torque at the rear wheels.\u003c\/li\u003e\n\u003cli\u003eIncludes required installation hardware and instructions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEnhances the truck’s exhaust note with a muscular Flowmaster performance sound.\u003c\/li\u003e\n\u003cli\u003eImproves exhaust flow for drivers seeking additional performance from their Ford F-150.\u003c\/li\u003e\n\u003cli\u003eMaintains a factory-style fit and appearance without requiring a complete exhaust replacement.\u003c\/li\u003e\n\u003cli\u003eProvides durable performance for daily driving, towing, and truck enthusiasts looking for an upgraded exhaust system.\u003c\/li\u003e\n\u003cli\u003eOffers a straightforward bolt-on upgrade that can be completed with common hand tools and basic mechanical skills.\u003c\/li\u003e\n\u003cli\u003eBacked by Flowmaster’s One (1) Year Limited Warranty for added product confidence.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Flowmaster\u003c\/li\u003e\n\u003cli\u003ePart Number: 718172\u003c\/li\u003e\n\u003cli\u003eProduct Type: Direct-fit exhaust muffler assembly\u003c\/li\u003e\n\u003cli\u003eExhaust Series: Flow FX\u003c\/li\u003e\n\u003cli\u003eMuffler Material: 409 Stainless Steel\u003c\/li\u003e\n\u003cli\u003ePipe Material: 409 Stainless Steel\u003c\/li\u003e\n\u003cli\u003eMuffler Color: Silver\u003c\/li\u003e\n\u003cli\u003eMuffler Finish: Natural\u003c\/li\u003e\n\u003cli\u003eMuffler Shape: Oval\u003c\/li\u003e\n\u003cli\u003eMuffler Type: Absorption\u003c\/li\u003e\n\u003cli\u003eMain Tubing Diameter: 3.00 inches\u003c\/li\u003e\n\u003cli\u003eBody Height: 4.00 inches\u003c\/li\u003e\n\u003cli\u003eBody Width: 9.00 inches\u003c\/li\u003e\n\u003cli\u003eMuffler Body Length: 14.00 inches\u003c\/li\u003e\n\u003cli\u003eOverall Length: 52.50 inches\u003c\/li\u003e\n\u003cli\u003eInlet Diameter: 3.00 inches\u003c\/li\u003e\n\u003cli\u003eOutlet Diameter: 3.00 inches\u003c\/li\u003e\n\u003cli\u003eOutlet Configuration: Dual\u003c\/li\u003e\n\u003cli\u003eInlet Location: Center\u003c\/li\u003e\n\u003cli\u003eOutlet Location: Dual\u003c\/li\u003e\n\u003cli\u003eMount Type: Factory hanger locations\u003c\/li\u003e\n\u003cli\u003eClamps Included: Yes\u003c\/li\u003e\n\u003cli\u003eHangers Included: Yes\u003c\/li\u003e\n\u003cli\u003eExhaust Tip Style: Not Included; reuses factory tips\u003c\/li\u003e\n\u003cli\u003eSound Level: Aggressive \/ Moderate\u003c\/li\u003e\n\u003cli\u003eEmission Code: 5\u003c\/li\u003e\n\u003cli\u003eCalifornia Proposition 65 Warning: Contains chemicals including chromium (hexavalent compounds) and nickel (metallic)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInstall Difficulty Level\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEasy installation with basic mechanical skills.
