Furthermore, OEM mild steel flex joints frequently tear, fray, and corrode over time due to engine pitch under load. This leads to exhaust leaks, loss of scavenging efficiency, increased in-cabin drone, and sluggish throttle response downstream of the catalytic converters.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from mandrel-bent \u003cstrong\u003eT304 stainless steel\u003c\/strong\u003e, this direct-fit performance Y-pipe features dual 2.5-inch inlet runners transitioning smoothly into a single 3.0-inch collector to maximize exhaust gas expansion. Heavy-duty double-braided internal flex bellows absorb drivetrain movement without cracking or unraveling. Thick CNC-machined flanges ensure leak-free seal integrity against high thermal cycling, restoring proper exhaust pulse synchronization across the cylinder banks.\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 Q40, Q50, 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;\"\u003eVQ37VHR \/ V36, V37, CV36\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;\"\u003e328 hp \/ 269 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;\"\u003eN\/A\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\u003e2014-2015 Infiniti Q50 3.7L Naturally Aspirated V6\u003c\/li\u003e\n  \u003cli\u003e2015 Infiniti Q40 3.7L Naturally Aspirated V6\u003c\/li\u003e\n  \u003cli\u003e2014-2015 Infiniti Q60 3.7L Naturally Aspirated V6\u003c\/li\u003e\n  \u003cli\u003eNote: Does not fit Q50 Hybrid (3.5L) or 2.0L \/ 3.0L Turbo models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the V36, V37, and CV36 Q40, Q50, Q60?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2014-2015 Infiniti Q40, Q50, and Q60 equipped with the \u003cstrong\u003eVQ37VHR\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eWill installing this Y-pipe trigger a Check Engine Light (CEL)?\u003c\/h4\u003e\n\u003cp\u003eNo, this component installs entirely downstream of the factory catalytic converters and primary oxygen sensors, preserving OEM sensor calibration without causing fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Infiniti Performance Standard\u003c\/h3\u003e\n\u003cp\u003eTailored for the naturally aspirated VQ platform, this upgrade refines the distinct 3.7L exhaust note by eliminating harsh rasp while opening up critical mid-to-high-RPM airflow for responsive, uninterrupted power delivery.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67531032920312,"sku":"DS-E1SA1Q8QN","price":234.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/y-pipe-exhaust-for-infiniti-q40-q50-q60-2014-2015-3-7l-1.jpg?v=1790528085","url":"https:\/\/performancechiptuning.com\/fr\/products\/y-pipe-exhaust-for-infiniti-q40-q50-q60-2014-2015-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
