Over time, sustained operating temperatures cause internal washcoat thermal degradation and structural breakdown of the ceramic honeycomb substrate. Carbon loading and oil blow-by common to aging variable valve timing engines contaminate precious metal sites, resulting in reduced exhaust throughput, increased backpressure, and persistent check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to original equipment dimensional tolerances, this replacement unit utilizes a high-durability stainless steel exterior shell that resists exterior corrosion and thermal fatigue. Inside, a dense ceramic monolith core coated with active catalytic washcoat materials maximizes surface contact area to efficiently convert hydrocarbons, carbon monoxide, and NOx without choking exhaust flow. Precision-machined, OE-spec flanges and integrated O2 sensor bungs ensure a leak-free seal without custom cutting or pipe modification.\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;\"\u003e2006-2011 Honda Civic\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;\"\u003eR18A1 1.8L I4 \/ FA1 (Sedan), FG1 (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;\"\u003e140 hp \/ 128 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;\"\u003eBER458340 (Interchange: 16448, 31383, 31722, 35129)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006-2011 Honda Civic DX 1.8L L4\u003c\/li\u003e\n  \u003cli\u003e2006-2011 Honda Civic EX 1.8L L4\u003c\/li\u003e\n  \u003cli\u003e2006-2011 Honda Civic LX 1.8L L4\u003c\/li\u003e\n  \u003cli\u003e2009-2011 Honda Civic DX-G 1.8L L4\u003c\/li\u003e\n  \u003cli\u003e2009-2011 Honda Civic LX-S 1.8L L4\u003c\/li\u003e\n  \u003cli\u003e2011 Honda Civic EX-L 1.8L L4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Honda Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered specifically for high-revving Honda i-VTEC platforms, this catalytic converter restores factory exhaust velocity and clean engine response without altering the signature intake or exhaust note.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50487878582520,"sku":"DS-E81E1NOUO","price":114.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-honda-civic-2006-2011-1-8l-1.jpg?v=1789142390","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-honda-civic-2006-2011-1-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
