Extreme duty cycles and repeated heat cycling cause the rigid cast-iron logs to warp, crack along the casting seams, and snap rear exhaust studs inside the cylinder head. Beyond persistent, ticking exhaust leaks, the restrictive factory log-style runner layout creates turbulent backpressure, choking cylinder scavenging and reducing torque under sustained load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct replacement header kit is constructed from high-grade stainless steel with smooth mandrel-bent primary tubes designed to equalize cylinder evacuation and maximize exhaust gas velocity. The precision-welded, extra-thick mounting flanges resist heat-induced warpage under high exhaust gas temperatures (EGTs), ensuring a gas-tight seal against the cylinder head ports. Designed as a direct bolt-on replacement for factory exhaust routing, this kit retains factory oxygen sensor bung locations to preserve accurate closed-loop fuel metering without requiring chassis modification.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\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;\"\u003e1997-2003 Ford F-150, 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;\"\u003e4.6L Modular V8 (2V) \/ PN-96\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;\"\u003e220-231 hp \/ 265-293 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;\"\u003eSPT-EHD1401\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1997-2003 Ford F-150 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e1997-1999 Ford F-250 (Light Duty \/ Under 8,500 GVWR) 4.6L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the PN-96 F-150, F-250?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1997-2003 Ford F-150 and F-250 light-duty trucks equipped with the \u003cstrong\u003e4.6L Modular 2V\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill installing these headers trigger a Check Engine Light (CEL)?\u003c\/strong\u003e\u003cbr\u003e No, because factory O2 sensor positions are retained in the correct flow stream, the factory powertrain control module maintains proper closed-loop fuel trim monitoring without throwing DTC codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Towing Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe towing, hauling, and high-temp duty cycles, this stainless steel header assembly restores lost low-end grunt while permanently curing the common cracked-manifold failures inherent to the 10th-generation Ford truck platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50607155675384,"sku":"DS-EVUYOXMYS","price":231.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-header-for-ford-f-150-f-250-1997-2003-4-6l-1.jpg?v=1790091054","url":"https:\/\/performancechiptuning.com\/products\/exhaust-header-for-ford-f-150-f-250-1997-2003-4-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
