In the 8th-gen platform, minor oil consumption over time accelerates carbon fouling across the catalytic washcoat, degrading precious metal reaction efficiency. This results in elevated exhaust backpressure, restricted top-end i-VTEC breathing, and recurrent catalytic threshold fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-on solution, this assembly features a durable stainless steel outer shell designed to withstand extreme thermal expansion and prevent heat-cycling fatigue. The internal high-flow ceramic substrate is loaded with catalytic washcoat formulated for Federal EPA standards. Precision-bent aluminized tubing ensures laminar exhaust flow, while thick OE-spec flanges match factory mounting points directly to avoid exhaust leaks and eliminate welding.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2008-2012 Honda Accord 2.4L\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eK24Z2, K24Z3 \/ CP2 (Sedan), CS1 (Coupe)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e177-190 hp \/ 161-162 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e18190-5J0-A00, 18190-R40-A00\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 LX 2.4L L4 (CP2)\u003c\/li\u003e\n  \u003cli\u003e2008-2012 Honda Accord LX-P 2.4L L4 (CP2)\u003c\/li\u003e\n  \u003cli\u003e2008-2012 Honda Accord EX 2.4L L4 (CP2 \/ CS1)\u003c\/li\u003e\n  \u003cli\u003e2008-2012 Honda Accord EX-L 2.4L L4 (CP2 \/ CS1)\u003c\/li\u003e\n  \u003cli\u003e2011-2012 Honda Accord SE 2.4L L4 (CP2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Honda Precision Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned to maintain balanced exhaust velocity, this converter maintains the specific backpressure curve required for smooth VTC cam phasing and prompt secondary O2 sensor readiness.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50464272482552,"sku":"DS-E3HRX17BE","price":129.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-honda-accord-2008-2012-2-4l-1.jpg?v=1788878864","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-honda-accord-2008-2012-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
