Designed strictly for mass-production efficiency, these OEM units utilize a log-style architecture that creates severe exhaust turbulence and high backpressure. As cylinders exhaust into a shared, restrictive chamber, the resulting reversion negatively impacts volumetric efficiency and chokes high-RPM horsepower. Furthermore, over thousands of thermal cycles, the factory cast manifolds are prone to heat-soak and gasket deterioration, robbing the engine of throttle response and masking the true exhaust note of the Modular V8.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Tubular Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThese upgraded shorty headers eliminate the factory log-style bottleneck by utilizing 1 5\/8-inch, 16-gauge cold-rolled steel primary tubing paired with a free-flowing Power Plenum collector. This tubular design smooths out exhaust gas pulses, significantly reducing backpressure and improving cylinder scavenging efficiency. The heavy-duty 3\/8-inch thick head flanges ensure a warp-free mating surface against the cylinder head, while integrated O-ringed port seals provide a superior, leak-proof barrier compared to standard flat gaskets. Because these are shorty-style headers, they bolt directly to the factory or aftermarket catalytic converters, maximizing underbody ground clearance for lowered S197 chassis while delivering an aggressive, deeper exhaust tone and measurable gains in mid-range torque.\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;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2005-2010 Ford Mustang GT\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4.6L 3-Valve Modular V8 \/ S197\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e300-315 hp \/ 320-325 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2010 Ford Mustang GT 1.625 in.
