Over continuous thermal cycling, these OEM cast units are susceptible to micro-cracking and warped flange surfaces, causing disruptive exhaust leaks before the catalytic converters. Internally, abrupt directional changes and mismatched runner lengths generate turbulent exhaust reversion pulses that stifle cylinder scavenging, trap excessive thermal load against the cylinder heads, and hinder mid-range torque production.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit header kit replaces the failure-prone cast assemblies with CNC-machined, precision-surfaced mounting flanges and mandrel-bent \u003cstrong\u003eT304 stainless steel\u003c\/strong\u003e primary tubing. Smooth-radius bends eliminate internal airflow turbulence, maintaining high-velocity laminar flow from the exhaust ports directly into the collector. Heavy-duty TIG welds provide structural integrity under aggressive thermal expansion, preventing warping and blowout at the cylinder head interface. Integrated factory-placement O2 sensor bungs allow seamless retention of primary oxygen sensors without harness stretching, restoring balanced scavenging across all six cylinders while mitigating underhood heat retention.\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;\"\u003e2005-2010 Ford Mustang\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;\"\u003e4.0L Cologne V6 \/ S197\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;\"\u003e210 hp \/ 240 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-EHD1338\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005 Ford Mustang 4.0L V6 (Base)\u003c\/li\u003e\n  \u003cli\u003e2006 Ford Mustang 4.0L V6 (Base)\u003c\/li\u003e\n  \u003cli\u003e2007 Ford Mustang 4.0L V6 (Base)\u003c\/li\u003e\n  \u003cli\u003e2008 Ford Mustang 4.0L V6 (Base)\u003c\/li\u003e\n  \u003cli\u003e2009 Ford Mustang 4.0L V6 (Base)\u003c\/li\u003e\n  \u003cli\u003e2010 Ford Mustang 4.0L V6 (Base)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the S197 Mustang?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2005-2010 Ford Mustang equipped with the \u003cstrong\u003e4.0L Cologne SOHC V6\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre factory O2 sensor extensions required for installation?\u003c\/strong\u003e\u003cbr\u003e No, the O2 bungs are placed in OEM-equivalent locations to allow the direct retention of factory upstream sensor harnesses.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Muscle Caliber\u003c\/h3\u003e\n\u003cp\u003eConstructed specifically for the \u003cstrong\u003eS197\u003c\/strong\u003e chassis, this header delivers durable gas-tight sealing, aggressive muscle car acoustic tone, and unchoked exhaust flow across the entire RPM band.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50607048098040,"sku":"DS-EH5TVAXKU","price":315.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-header-for-ford-mustang-2005-2010-4-0l-1.jpg?v=1790090938","url":"https:\/\/performancechiptuning.com\/fr\/products\/exhaust-header-for-ford-mustang-2005-2010-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
