Over time, the factory substrate suffers washcoat breakdown, cell sintering, and eventual core blockage. This degradation creates elevated exhaust backpressure, robbing high-RPM VTEC power, increasing engine operating temps, and triggering persistent check engine lights (DTC P0420). Additionally, the OEM flanges often corrode, compromising the seal and causing pre-converter exhaust leaks.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a bolt-on replacement, this catalytic assembly utilizes a heavy-gauge stainless steel outer shell designed to resist road salt corrosion and severe thermal cycling. Inside, a durable ceramic honeycomb substrate features an optimized washcoat of precious metals to ensure full chemical conversion of HC, CO, and NOx emissions. Laser-cut mating flanges ensure an exact match to the factory exhaust manifold and intermediate pipe, preserving proper O2 sensor placement without custom welding. The package includes heavy-duty replacement hardware and high-temperature seals to eliminate exhaust leaks and restore factory scavenging dynamics.\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;\"\u003e2006-2011 Honda Civic 2.0L\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;\"\u003e\n\u003cstrong\u003eK20Z3\u003c\/strong\u003e \/ \u003cstrong\u003eFG2\u003c\/strong\u003e (Coupe), \u003cstrong\u003eFA5\u003c\/strong\u003e (Sedan)\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;\"\u003e197 hp \/ 139 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;\"\u003e\u003cstrong\u003e16695\u003c\/strong\u003e\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 Si Coupe 2.0L L4 (\u003cstrong\u003eFG2\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e2007-2011 Honda Civic Si Sedan 2.0L L4 (\u003cstrong\u003eFA5\u003c\/strong\u003e)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the FG2 and FA5 Civic?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2006-2011 Honda Civic equipped with the \u003cstrong\u003eK20Z3\u003c\/strong\u003e 2.0L engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this converter resolve a P0420 diagnostic trouble code?\u003c\/strong\u003e\u003cbr\u003e Yes, it provides the required chemical conversion efficiency to satisfy downstream oxygen sensor monitoring and clear P0420 faults when paired with functioning O2 sensors.\u003c\/p\u003e\n\n\u003ch3\u003eThe Honda Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand the demanding exhaust velocity of Honda's high-revving DOHC i-VTEC platform, this catalytic assembly preserves factory exhaust harmonics while ensuring clean, reliable operation across the entire RPM band.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501652578552,"sku":"DS-E0VKUKHNL","price":167.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-honda-civic-2006-2011-2-0l-front-1.jpg?v=1789329214","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-honda-civic-2006-2011-2-0l-front","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
