Over time, prolonged exposure to high exhaust gas temperatures breaks down the internal honeycomb core, causing substrate sintering, structural fracturing, and wash-coat wash-out. This thermal fatigue triggers persistent downstream P0420 and P0430 diagnostic fault codes, creates excessive exhaust backpressure, chokes cylinder scavenging at high RPM, and reduces overall engine volumetric efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement converter pair utilizes a robust stainless steel outer shell engineered to withstand road debris impacts and severe thermal expansion without seam fatigue. Internally, a dense, high-porosity ceramic honeycomb substrate loaded with precious catalytic wash-coat metals ensures efficient catalytic reduction of NOx, CO, and hydrocarbons back within stoichiometric limits. Each assembly features precision laser-cut, thick-gauge mounting flanges that match OEM exhaust header downpipes and mid-pipe connections to prevent high-temperature exhaust gas blow-by. CNC-placed oxygen sensor bungs retain factory sensor clocking, eliminating harness stretch and ensuring direct plug-and-play installation without custom fabrication.\u003c\/p\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;\"\u003e2014-2015 Infiniti Q60\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\u003eVQ37VHR\u003c\/strong\u003e 3.7L V6 \/ \u003cstrong\u003eCV36\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;\"\u003e330 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\u003e15H5485\u003c\/strong\u003e, \u003cstrong\u003e15H5484\u003c\/strong\u003e, \u003cstrong\u003e16197\u003c\/strong\u003e, \u003cstrong\u003e16198\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\u003e2014 Infiniti Q60 Base Coupe 3.7L V6 (VQ37VHR)\u003c\/li\u003e\n  \u003cli\u003e2014 Infiniti Q60 Journey Coupe 3.7L V6 (VQ37VHR)\u003c\/li\u003e\n  \u003cli\u003e2014 Infiniti Q60 Premium \/ Sport Coupe 3.7L V6 (VQ37VHR)\u003c\/li\u003e\n  \u003cli\u003e2014 Infiniti Q60 Base \/ Premium Convertible 3.7L V6 (VQ37VHR)\u003c\/li\u003e\n  \u003cli\u003e2015 Infiniti Q60 Base Coupe 3.7L V6 (VQ37VHR)\u003c\/li\u003e\n  \u003cli\u003e2015 Infiniti Q60 Journey Coupe 3.7L V6 (VQ37VHR)\u003c\/li\u003e\n  \u003cli\u003e2015 Infiniti Q60 Sport Coupe \/ Convertible 3.7L V6 (VQ37VHR)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the CV36 Q60?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2014-2015 Infiniti Q60 equipped with the \u003cstrong\u003eVQ37VHR\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eAre these converters 50-state emissions legal?\u003c\/h4\u003e\n\u003cp\u003eThese units meet EPA 48-state emissions standards and cannot be legally installed or registered in California or New York.\u003c\/p\u003e\n\n\u003ch3\u003eThe Infiniti Performance Caliber\u003c\/h3\u003e\n\u003cp\u003ePreserve the distinct, high-revving exhaust note and scavenged V6 torque of the \u003cstrong\u003eVQ37VHR\u003c\/strong\u003e powertrain with an exhaust assembly designed to handle sustained high-RPM operation and aggressive road heat.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67537673748728,"sku":"DS-EZRZJXAF5","price":181.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-infiniti-q60-2014-2015-3-7l-left-right-1.jpg?v=1790613673","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-infiniti-q60-2014-2015-3-7l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
