Over prolonged thermal cycling, these OEM cast units are prone to heat fatigue, hairline cracking, and localized thermal retention around cylinder number three. Furthermore, the cramped, rough internal casting walls produce turbulent exhaust reversion, preventing clean cylinder evacuation during valve overlap and stifling top-end volumetric efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to eliminate internal turbulence, this performance tubular manifold features mandrel-bent \u003cstrong\u003eT-304 stainless steel\u003c\/strong\u003e runners configured in an optimal primary geometry for superior pulse scavenging. Smooth transitions into a merged collector dramatically lower backpressure while maintaining high exhaust gas velocity (EGV). Precision TIG welding prevents thermal stress fracturing under aggressive load, while heavy-duty, CNC-machined mounting flanges resist warping against the aluminum cylinder head to eradicate exhaust gas leaks. The kit includes pre-welded oxygen sensor bungs and mounting hardware for a straightforward bolt-on installation.\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;\"\u003e1995-1999 Mitsubishi Eclipse (Non-Turbo)\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;\"\u003e2.0L 420A DOHC \/ D31A (2G)\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;\"\u003e140 hp \/ 130 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\u003e1995-1999 Mitsubishi Eclipse Base 2.0L L4 Non-Turbo\u003c\/li\u003e\n  \u003cli\u003e1995-1999 Mitsubishi Eclipse RS 2.0L L4 Non-Turbo\u003c\/li\u003e\n  \u003cli\u003e1995-1999 Mitsubishi Eclipse GS 2.0L L4 Non-Turbo\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the D31A Eclipse?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1995-1999 Mitsubishi Eclipse equipped with the 2.0L naturally aspirated \u003cstrong\u003e420A\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this exhaust header throw a Check Engine Light (CEL)?\u003c\/strong\u003e\u003cbr\u003e No, the manifold retains proper upstream oxygen sensor bung placement to maintain factory air-fuel readings without triggering secondary O2 catalyst diagnostic codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mitsubishi Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eUnlock the signature rev-happy exhaust note and mechanical efficiency inherent to your second-generation platform.
