In the transverse MZI\/Cyclone V6 layout, elevated exhaust gas temperatures degrade the internal ceramic monolith, causing cell wall collapse, accelerated flow restriction, and reduced catalyst washcoat efficiency. This structural breakdown restricts scavenging, generates excessive backpressure that saps mid-range torque, and trips persistent catalyst efficiency check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a bolt-on solution, this assembly features a durable stainless steel outer shell designed to withstand road debris impacts and thermal expansion. Internally, a high-efficiency ceramic honeycomb substrate provides optimal precious metal surface area to oxidize carbon monoxide and unburnt hydrocarbons while reducing nitrogen oxides. Precision-welded, OEM-spec flanges align flush with factory mating surfaces, utilizing the supplied hardware and gaskets to ensure a gas-tight seal that prevents post-manifold exhaust leaks and O2 sensor signaling errors.\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;\"\u003e2007-2015 Mazda CX-9\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;\"\u003eFord Cyclone (MZI 3.5L \/ 3.7L DOHC V6) \/ TB Chassis\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;\"\u003e263-273 hp \/ 249-270 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePlacement \/ Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eRear \/ Right \/ Direct Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eMaterials\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eStainless Steel Body \/ Ceramic Substrate\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;\"\u003eBER302940 (Interchange: 16491)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2007 Mazda CX-9:\u003c\/strong\u003e 3.5L V6 (Sport, Touring, Grand Touring)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2008 Mazda CX-9:\u003c\/strong\u003e 3.7L V6 (Sport, Touring, Grand Touring)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2009 Mazda CX-9:\u003c\/strong\u003e 3.7L V6 (Sport, Touring, Grand Touring)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2010 Mazda CX-9:\u003c\/strong\u003e 3.7L V6 (Sport, Touring, Grand Touring)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2011 Mazda CX-9:\u003c\/strong\u003e 3.7L V6 (Sport, Touring, Grand Touring)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2012 Mazda CX-9:\u003c\/strong\u003e 3.7L V6 (Sport, Touring, Grand Touring)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2013 Mazda CX-9:\u003c\/strong\u003e 3.7L V6 (Sport, Touring, Grand Touring)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2014 Mazda CX-9:\u003c\/strong\u003e 3.7L V6 (Sport, Touring, Grand Touring)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2015 Mazda CX-9:\u003c\/strong\u003e 3.7L V6 (Sport, Touring, Grand Touring)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mazda Reliability Caliber\u003c\/h3\u003e\n\u003cp\u003ePreserve your crossover's powertrain reliability with an emissions unit built to match factory backpressure thresholds, ensuring smooth power delivery and consistent sensor feedback without triggering check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50489042960632,"sku":"DS-E9MUZQ965","price":63.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-mazda-cx-9-2007-2015-3-5l-3-7l-1.jpg?v=1789156578","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-mazda-cx-9-2007-2015-3-5l-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
