These OEM components restrict exhaust gas velocity and trap thermal energy under load.

Centered around a single 3-inch inlet to dual 2.5-inch outlet Flowsound 2-chamber chambered muffler, the system optimizes directional scavenging while canceling harsh drone frequencies. Dual tailpipes run parallel to the outer frame rail, clearing factory-sized spare tires and OEM receiver hitches across all wheelbase configurations.\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;\"\u003e1998-2006 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;\"\u003e4.2L Essex V6 \/ PN-96 \u0026amp; P221\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;\"\u003e205 hp \/ 255 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\u003e1998-2006 Ford F-150 4.2L V6 (Gasoline \u0026amp; Flex-Fuel models equipped with factory single-inlet muffler only)\u003c\/li\u003e\n  \u003cli\u003eFits all cab styles and wheelbase lengths with factory spare tire and OEM receiver hitch\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 PN-96 \/ P221 F-150?\u003c\/h4\u003e\n\u003cp\u003eYes, this is designed for the 1998-2006 Ford F-150 equipped with the \u003cstrong\u003eEssex V6\u003c\/strong\u003e 4.2L engine; \u003cstrong\u003eit does not fit models with factory dual-inlet mufflers, nor does it include components forward of the muffler inlet\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch4\u003eIs this exhaust kit a direct bolt-on installation?\u003c\/h4\u003e\n\u003cp\u003eNo, this is a custom installer kit that may require cutting, fabrication, or pipe adaptation, and exhaust tips are not included.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Truck Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for work-truck durability, the heavy-gauge aluminized construction withstands sustained thermal cycling under heavy hauling while maintaining rigid ground clearance over rough terrain.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67562638704888,"sku":"DS-EOJI78KBE","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-150-1998-2006-4-2l-1.jpg?v=1790988298","url":"https:\/\/performancechiptuning.com\/es\/products\/exhaust-kit-for-ford-f-150-1998-2006-4-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
