On both the \u003cstrong\u003e4.6L 3V Modular\u003c\/strong\u003e and supercharged \u003cstrong\u003e5.4L DOHC\u003c\/strong\u003e engines, internal baffles and pinched factory tailpipe bends induce thermal buildup and parasitic backpressure. This bottleneck restricts volumetric efficiency at upper RPM thresholds and significantly muffles the vehicle's natural exhaust sound.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-on upgrade, this axle-back system utilizes continuous mandrel-bent stainless steel tubing to maintain uniform internal diameter and eliminate turbulent flow pockets. High-flow straight-through mufflers optimize exhaust gas scavenging without drone, while robust TIG-welded structural joints ensure resistance against thermal fatigue and road corrosion. Integrated OEM-style hanger rods and precision-formed mounting flanges align with factory intermediate pipes, seating polished exhaust tips flush within the rear bumper cutouts without requiring cutting or 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;\"\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;\"\u003eModular V8 (4.6L \/ 5.4L) \/ \u003cstrong\u003eS197\u003c\/strong\u003e\n\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;\"\u003e300-540 hp \/ 320-510 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 (MPN: SPT-EHD1590)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005-2010 Ford Mustang GT 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2008-2009 Ford Mustang Bullitt 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e2007-2010 Ford Mustang Shelby GT500 5.4L Supercharged 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 S197 Mustang?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2005-2010 Ford Mustang equipped with the \u003cstrong\u003eModular 4.6L\u003c\/strong\u003e or \u003cstrong\u003e5.4L\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this axle-back exhaust require a custom ECU tune or trigger a CEL?\u003c\/strong\u003e\u003cbr\u003e No, because this system bolts downstream of the factory catalytic converters and oxygen sensors, it will not trigger a check engine light or require PCM recalibration.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Muscle Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered specifically for classic American performance, this stainless steel system frees up exhaust flow, sheds dead weight over the rear axle, and delivers the authoritative muscle car roar that the \u003cstrong\u003eS197\u003c\/strong\u003e platform demands.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50607706013944,"sku":"DS-EPTPJGIA7","price":205.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/axle-back-exhaust-for-ford-mustang-2005-2010-4-6l-5-4l-1.jpg?v=1790091458","url":"https:\/\/performancechiptuning.com\/fr\/products\/axle-back-exhaust-for-ford-mustang-2005-2010-4-6l-5-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
