Over time, physical carbon fouling and core erosion restrict exhaust gas velocity, creating excessive upstream backpressure. This bottleneck forces elevated cylinder head temperatures, reduces volumetric efficiency, and triggers persistent catalyst efficiency threshold failure codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eFabricated with a heavy-gauge stainless steel outer casing and a high-porosity ceramic honeycomb substrate, this direct-fit unit handles intense exhaust gas thermal expansion without shell fatigue or internal cracking. The substrate core optimizes surface contact for clean catalytic reduction of hydrocarbons, carbon monoxide, and NOx while minimizing backpressure. Integrated OE-style flanges, factory-matched oxygen sensor bungs, and supplied mounting hardware provide a precise, bolt-on seal with zero 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;\"\u003e2009-2019 Nissan Murano\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;\"\u003eVQ35DE \/ Z51, Z52\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;\"\u003e260 hp \/ 240 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;\"\u003eBER454395 (Interchange: 16700, 16702, 40885)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2014 Nissan Murano 3.5L V6 (Z51 Chassis)\u003c\/li\u003e\n  \u003cli\u003e2015-2019 Nissan Murano 3.5L V6 (Z52 Chassis)\u003c\/li\u003e\n  \u003cli\u003ePosition: Front \/ Left \/ Right (Application Specific Direct Replacement)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to match tight Japanese OEM tolerances, this converter preserves the smooth acoustic signature and broad powerband expected from Nissan's VQ platform while ensuring uncompromised emissions system integrity.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50487875600632,"sku":"DS-EBHRRH32S","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-nissan-murano-2009-2019-3-5l-1.jpg?v=1789142184","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-nissan-murano-2009-2019-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
