Over time, stock ceramic substrates suffer washcoat degradation, carbon fouling, and structural crumbling. This failure pattern generates severe exhaust backpressure, robs engine power, and triggers persistent check engine lights. In extreme cases, fragmented ceramic dust can migrate back into the combustion chambers via valve overlap, scoring cylinder walls.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed with durable stainless steel outer shells, these direct-replacement converters house high-efficiency ceramic honeycomb monoliths engineered with an optimal precious metal washcoat to effectively neutralize HC, CO, and NOx emissions. Laser-cut, heavy-gauge mounting flanges prevent thermal warping and exhaust blow-by. Mandrel-formed collector sections maintain optimal exhaust gas velocity, restoring factory scavenging efficiency and engine responsiveness.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Front Left Catalytic Converter\u003c\/li\u003e\n  \u003cli\u003e1x Front Right Catalytic Converter\u003c\/li\u003e\n  \u003cli\u003eMounting Hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2010-2013 Acura MDX, ZDX\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\u003eJ37A1 \/ J37A5\u003c\/strong\u003e \/ \u003cstrong\u003eYD2, YB1\u003c\/strong\u003e\n\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;\"\u003e300 hp \/ 270 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\n\u003cstrong\u003e16643\u003c\/strong\u003e, \u003cstrong\u003e16658\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2010-2013 Acura MDX 3.7L V6 (YD2 Chassis)\u003c\/li\u003e\n  \u003cli\u003e2010-2013 Acura ZDX 3.7L V6 (YB1 Chassis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the YD2 \/ YB1 MDX, ZDX?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2010-2013 Acura MDX, ZDX equipped with the \u003cstrong\u003eJ37\u003c\/strong\u003e 3.7L engine. \u003cstrong\u003eNot legal for sale or use in California or New York on emissions-controlled vehicles.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWill the original factory heat shields transfer over directly?\u003c\/h4\u003e\n\u003cp\u003eDue to aftermarket exterior canister geometry, the factory heat shields do not fit perfectly and may require light modification or omission during professional installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Acura Caliber\u003c\/h3\u003e\n\u003cp\u003eHonda's high-revving 3.7L VTEC platform demands clean, unhindered exhaust scavenging to maintain linear power delivery.
