The constant-radius mandrel bends prevent cross-sectional collapse along corners to optimize exhaust velocity and decrease boundary-layer friction. Aluminized steel construction resists oxidation and road debris impact. The tailpipes exit parallel to the frame rails behind the rear wheels, engineered specifically to clear factory-dimension spare tires and OEM receiver hitches.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Flowsound 2-chamber muffler (single 3\" inlet, dual 2.5\" outlets)\u003c\/li\u003e\n  \u003cli\u003e2 aluminized mandrel-bent two-piece 2.5\" tail pipes (slip-together)\u003c\/li\u003e\n  \u003cli\u003e8 muffler clamps\u003c\/li\u003e\n  \u003cli\u003e1 larger exhaust clamp\u003c\/li\u003e\n  \u003cli\u003e4 rubber-insulated hangers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2007-2009 Ford F-250\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eModular 4.6L V8 \/ P221 \/ P473\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e248 hp \/ 294 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007-2009 Ford F-250 4.6L gasoline and flex-fuel (factory single-inlet muffler only, all wheelbases)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the P221\/P473 F-250?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2009 Ford F-250 equipped with the \u003cstrong\u003eModular 4.6L\u003c\/strong\u003e engine. \u003cstrong\u003eExcludes trucks equipped from the factory with dual-inlet mufflers, does not include components forward of the muffler, and does not include exhaust tips.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eIs this a direct bolt-on installation?\u003c\/h4\u003e\n\u003cp\u003eNo, this is a universal-fit fabricator kit requiring an experienced installer to adjust or adapt pipe sections, especially if modified suspension, aftermarket wheels, or oversize tires alter underbody clearances.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eConstructed to meet rigorous fleet and towing demands, this system provides durable aluminized steel construction and unrestricted gas flow designed to sustain prolonged high-temperature duty cycles without failure.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67562636050680,"sku":"DS-EUEP4AWU3","price":229.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-kit-for-ford-f-250-2007-2009-4-6l-1.jpg?v=1790988153","url":"https:\/\/performancechiptuning.com\/products\/exhaust-kit-for-ford-f-250-2007-2009-4-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
