Over time, road salt and continuous thermal cycling degrade the mild steel, rotting flange welds and muffler seams. Mechanically, the factory press bends pinch internal pipe volume by up to 25%, producing parasitic exhaust gas scavenging loss and excessive thermal retention behind the catalytic converter that chokes the naturally aspirated \u003cstrong\u003e4G64\u003c\/strong\u003e powerplant.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-on upgrade, this performance cat-back system utilizes continuous mandrel-bent \u003cstrong\u003eT-304 stainless steel\u003c\/strong\u003e piping to maintain constant cross-sectional area throughout every radius. Smooth internal geometry optimizes exhaust gas velocity (EGV), lowering backpressure to enhance scavenging across the mid-to-high RPM range. Heavy-duty TIG-welded flanges and OE-location mounting hangers eliminate bracket fatigue under high vibrational loads. Completed with a low-restriction straight-through performance muffler and a polished tip, this assembly provides exceptional oxidation resistance, structural durability, and a clean, deep exhaust tone without high-frequency cabin drone.\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;\"\u003e2000-2005 Mitsubishi Eclipse\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;\"\u003e4G64 \/ D52A\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;\"\u003e154 hp \/ 163 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;\"\u003eSPT-CAT1255\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2000-2005 Mitsubishi Eclipse RS Coupe 2.4L L4 (4G64)\u003c\/li\u003e\n  \u003cli\u003e2000-2005 Mitsubishi Eclipse GS Coupe 2.4L L4 (4G64)\u003c\/li\u003e\n  \u003cli\u003e2001-2005 Mitsubishi Eclipse GS Spyder 2.4L L4 (4G64)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the D52A Eclipse?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2000-2005 Mitsubishi Eclipse equipped with the 4G64 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this cat-back exhaust trigger a Check Engine Light (CEL)?\u003c\/strong\u003e\u003cbr\u003e No, because this system bolts downstream of the factory catalytic converter and oxygen sensors, it will not trigger emission-related DTCs or fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mitsubishi JDM Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eTailored specifically for sport-compact tuners, this system uncorks the raw, resonant sound and dynamic rev characteristics that the inline-four platform was engineered to deliver.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50607708569848,"sku":"DS-EONPQBODP","price":196.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/cat-back-exhaust-for-mitsubishi-eclipse-2000-2005-2-4l-1.jpg?v=1790091481","url":"https:\/\/performancechiptuning.com\/es\/products\/cat-back-exhaust-for-mitsubishi-eclipse-2000-2005-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
