Over time, the factory ceramic washcoat inside the stock rear converter suffers from catalyst washcoat sintering and thermal breakdown. This degradation leads to restricted cell pathways, increased backpressure, deteriorated downstream hydrocarbon oxidation, and persistent catalyst system efficiency DTCs (P0420\/P0430) on the factory ECU.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement unit features a high-grade stainless steel outer shell and neck construction, engineered to resist road salt corrosion and thermal fatigue. Inside, an advanced ceramic honeycomb substrate is coated with an optimal precious metal washcoat (platinum, palladium, rhodium) to efficiently oxidize unburned hydrocarbons and carbon monoxide without choking exhaust gas velocity. Precision-aligned, robotically welded mounting flanges eliminate the need for custom fabrication, mating directly to the OEM Y-pipe and mid-pipe flanges. Heavy-duty replacement hardware and compression sealing gaskets are included to ensure leak-free exhaust sealing under continuous high-temperature duty cycles.\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;\"\u003e2001-2002 Acura MDX\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;\"\u003eJ35A3 \/ YD1\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;\"\u003e240 hp \/ 245 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;\"\u003e18160-PGK-A00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2001 Acura MDX Base 3.5L V6 (J35A3)\u003c\/li\u003e\n  \u003cli\u003e2001 Acura MDX Touring 3.5L V6 (J35A3)\u003c\/li\u003e\n  \u003cli\u003e2002 Acura MDX Base 3.5L V6 (J35A3)\u003c\/li\u003e\n  \u003cli\u003e2002 Acura MDX Touring 3.5L V6 (J35A3)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the YD1 MDX?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2001-2002 Acura MDX equipped with the \u003cstrong\u003eJ35A3\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this resolve downstream oxygen sensor check engine lights?\u003c\/strong\u003e\u003cbr\u003e Yes, provided upstream fuel trims and secondary O2 sensors are functioning within factory specifications, this unit restores OEM conversion efficiency and clears catalyst DTCs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Acura Engineering Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the real-world utility and all-weather driving expected of Honda's premium crossover platform, this exhaust component maintains critical backpressure balance to preserve low-end torque output without triggering downstream emissions faults.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501697995000,"sku":"DS-ESEZ6UCC2","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-acura-mdx-2001-2002-3-5l-rear-1.jpg?v=1789329653","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-acura-mdx-2001-2002-3-5l-rear","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
