Over time, continuous thermal cycling causes the factory ceramic honeycomb matrix to crumble, melt, or poison its washcoat, creating elevated exhaust backpressure. This restriction chokes exhaust scavenging downstream of the primary warm-up pre-cats, triggering downstream oxygen sensor DTCs such as P0420\/P0430, degrading fuel economy, and blunting wide-open-throttle acceleration.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement rear catalytic converter assembly features a heavy-gauge 409 stainless steel shell engineered to withstand road debris, thermal expansion, and road salt corrosion. Internally, a dense, high-flow ceramic substrate is washcoated with an optimized precious metal formulation that ensures rapid light-off and comprehensive catalytic reduction of NOx, CO, and hydrocarbons. Mandrel-bent transition cones maintain laminar exhaust gas velocity without creating turbulent hot spots. Precision laser-cut flanges and automated TIG welding ensure a leak-free, bolt-on seal directly to the factory mid-pipe and muffler assembly using the included hardware.\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;\"\u003e2008-2012 Honda Accord\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;\"\u003eJ35Z2 \/ J35Z3 \/ CP3 \/ CS2\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;\"\u003e268-271 hp \/ 248-254 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;\"\u003eHDAC021\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2008-2012 Honda Accord EX Sedan 3.5L V6 (CP3)\u003c\/li\u003e\n  \u003cli\u003e2008-2012 Honda Accord EX-L Sedan 3.5L V6 (CP3)\u003c\/li\u003e\n  \u003cli\u003e2008-2012 Honda Accord EX Coupe 3.5L V6 (CS2)\u003c\/li\u003e\n  \u003cli\u003e2008-2012 Honda Accord EX-L Coupe 3.5L V6 (CS2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the CP3 Accord?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2008-2012 Honda Accord equipped with the 3.5L J35 V6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs welding or custom pipe fabrication required to install this converter?\u003c\/strong\u003e\u003cbr\u003e No, this assembly features direct-fit, bolt-on flanges designed to mount directly to factory exhaust mounting locations using the included hardware.\u003c\/p\u003e\n\n\u003ch3\u003eThe Honda J-Series Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to complement the rev-happy harmonics and VTEC delivery of the 3.5L J-Series powerplant, this converter restores precise backpressure balance for smooth throttle tip-in, crisp exhaust resonance, and factory emissions compliance outside CARB-restricted states.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501118722296,"sku":"DS-EU87HQSQ7","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-honda-accord-2008-2012-3-5l-rear-1.jpg?v=1789326166","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-honda-accord-2008-2012-3-5l-rear","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
