For the high-revving \u003cstrong\u003eDuratec 37\u003c\/strong\u003e (Cyclone V6), this creates substantial exhaust backpressure at mid-to-high RPMs, trapping thermal energy near the rear axle assembly and limiting the engine's natural volumetric efficiency during heavy payload or towing demands.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis dual muffler-back system integrates a high-flow Flowsound two-chamber muffler featuring a single 3-inch inlet split into dual 2.5-inch outlets. The system utilizes mandrel-bent 2.5-inch aluminized steel tailpipes that maintain consistent cross-sectional area throughout every radius, preventing laminar flow detachment. The pipes are routed parallel with the outside frame rails to clear OEM receiver hitches and factory-sized spare tire assemblies across all wheelbase configurations, optimizing gas velocity while providing durable corrosion resistance.\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: solid font-size: min-width:\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;\"\u003e2011-2013 Ford F-150\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;\"\u003eCyclone 3.7L \/ P415\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;\"\u003e302 hp \/ 278 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\u003e2011-2013 Ford F-150 3.7L V6 Gasoline (Factory single-inlet muffler configurations)\u003c\/li\u003e\n  \u003cli\u003e2011-2013 Ford F-150 3.7L V6 Flex-Fuel (Factory single-inlet muffler configurations)\u003c\/li\u003e\n  \u003cli\u003eFits all cab sizes and bed lengths (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 P415 F-150?\u003c\/h4\u003e\n\u003cp\u003eYes, this fits the 2011-2013 Ford F-150 equipped with the \u003cstrong\u003eCyclone 3.7L\u003c\/strong\u003e engine. \u003cstrong\u003eDoes not fit dual-inlet factory muffler setups, 3.5L EcoBoost, 5.0L Coyote, or 6.2L V8 configurations, nor does it include components forward of the muffler.\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 custom-fit builder kit requiring an experienced installer; intermediate pipe fabrication or hanger modification may be required based on wheelbase variations and aftermarket suspension clearances.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for the demands of the working truck, this aluminized setup withstands the thermal cycling and mechanical vibration encountered during rigorous hauling and high-tongue-weight towing.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67562635657464,"sku":"DS-E2W09Z2ET","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-150-2011-2013-3-7l-1.jpg?v=1790988118","url":"https:\/\/performancechiptuning.com\/products\/exhaust-kit-for-ford-f-150-2011-2013-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
