From an airflow perspective, the factory casting features sharp, unequal-length runners with rough internal walls and abrupt collector angles. This restrictive geometry creates high exhaust gas reversion and uneven cylinder backpressure, choking exhaust gas scavenging and limiting upper-RPM volumetric efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from mandrel-bent stainless steel tubing, this header delivers smooth exhaust gas expansion and accelerated flow velocities. The smooth-radius primary runners equalize backpressure across all cylinders, improving combustion efficiency and throttle response. Precision TIG-welded joints and thick, warp-resistant mounting flanges ensure a leak-free seal under severe thermal cycling. The included direct-fit flex pipe decouples engine rocking motion from the rest of the cat-back system, actively preventing stress fractures at the collector.\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;\"\u003e1997-2002 Mitsubishi Mirage\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;\"\u003e4G93 \/ CJ\/CK\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;\"\u003e113 hp \/ 116 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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1997-2002 Mitsubishi Mirage LS (1.8L I4 SOHC)\u003c\/li\u003e\n  \u003cli\u003e1997-2002 Mitsubishi Mirage DE (1.8L I4 SOHC)\u003c\/li\u003e\n  \u003cli\u003e1997-2002 Mitsubishi Mirage Coupe \u0026amp; Sedan (1.8L I4)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the CJ\/CK Mirage?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1997-2002 Mitsubishi Mirage equipped with the 4G93 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this header include factory oxygen sensor bungs?\u003c\/strong\u003e\u003cbr\u003e Yes, it features pre-welded O2 sensor bungs in the stock configuration for straightforward sensor reinstallation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mitsubishi Sport Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand aggressive track sessions and daily street operation, this stainless header optimizes power delivery throughout the midrange while providing an aggressive, clean exhaust note on the naturally aspirated 4G-series platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50512353624312,"sku":"DS-E68ZG9CYU","price":184.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-header-for-mitsubishi-mirage-1997-2002-1-8l-1.jpg?v=1789426061","url":"https:\/\/performancechiptuning.com\/products\/exhaust-header-for-mitsubishi-mirage-1997-2002-1-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
