Over extended mileage, the OEM substrate suffers thermal fracture and carbon fouling, generating excessive exhaust backpressure. This restriction chokes exhaust scavenging, compromises upstream cylinder evacuation, and inevitably triggers downstream O2 sensor catalyst efficiency faults (DTC P0420\/P0430).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM geometric tolerances, this direct-fit catalytic converter features a heavy-gauge stainless steel outer shell designed to resist galvanic corrosion and road-salt degradation. Internally, a high-flow ceramic honeycomb substrate is coated with active precious metals to efficiently scrub hydrocarbons, carbon monoxide, and NOx without restricting flow velocity. Precision-machined, OE-spec mating flanges and integrated oxygen sensor bungs ensure leak-free sealing and accurate sensor feedback without custom fabrication.\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;\"\u003e2009-2013 Mazda 6\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;\"\u003eDuratec 37 (MZI 3.7L) \/ GH 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;\"\u003e272 hp \/ 269 lb-ft (Approx)\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  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePosition \/ Substrate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eRear\/Right \/ Ceramic Substrate, Stainless Steel Body\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\u003eMake:\u003c\/strong\u003e Mazda\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel Years:\u003c\/strong\u003e 2009, 2010, 2011, 2012, 2013\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEngine Configuration:\u003c\/strong\u003e 3.7L V6 Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlacement on Vehicle:\u003c\/strong\u003e Rear \/ Right\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Hardware:\u003c\/strong\u003e Gaskets and installation bolts included\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mazda Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eDesigned to maintain the smooth power delivery and signature throttle response of Mazda's flagship V6, this direct-fit unit preserves clean emissions output without robbing high-rpm exhaust scavenging.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50489025691896,"sku":"DS-ENO79LVNX","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-6-2009-2013-3-7l-1.jpg?v=1789156547","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-mazda-6-2009-2013-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
