These factory units feature extremely tight, non-mandrel-bent internal passages and unequal runner lengths that create significant turbulent interference between exhaust pulses. This backpressure traps heat within the cylinder head and forces the piston to work harder to evacuate spent gases, effectively 'choking' the 1.6L Alpha II engine. Over time, these cast units are susceptible to heat-soak, which further diminishes air-density and overall throttle response during sustained operation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 4-1 long-tube header is engineered to rectify these flow bottlenecks using mandrel-bent stainless steel tubing. Featuring 1-5\/8 inch OD primary runners that merge into a 2-1\/4 inch OD collector, the design utilizes precise timing of exhaust pulses to create a vacuum effect (scavenging) that draws spent gases out more efficiently. The CNC-machined flanges ensure a true, warp-resistant mating surface against the cylinder head, while the TIG-welded construction provides the structural integrity needed to handle high thermal expansion cycles. By smoothing the transition from the exhaust ports, this header facilitates a higher mass flow rate, resulting in documented gains of 10-15 horsepower and torque across the mid-to-high RPM range.\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;\"\u003e2006-2011 Hyundai Accent, Kia Rio \/ Rio5\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;\"\u003e1.6L Alpha II (G4ED) \/ MC \u0026amp; JB Chassis\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;\"\u003e110 hp \/ 106 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\u003e2006-2011 Hyundai Accent (1.6L Engine)\u003c\/li\u003e\n  \u003cli\u003e2006-2011 Kia Rio (1.6L Engine)\u003c\/li\u003e\n  \u003cli\u003e2006-2011 Kia Rio5 (1.6L Engine)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Hyundai, Kia Performance Standard\u003c\/h3\u003e\n\u003cp\u003eFor the Alpha II platform, reducing exhaust restriction is the most effective way to improve power-to-weight ratios.
