As the \u003cstrong\u003eN62B48\u003c\/strong\u003e 4.8L naturally aspirated V8 accumulates mileage, sustained high exhaust gas temperatures and minor oil consumption degrade the OEM precious-metal substrates. This matrix breakdown triggers persistent P0420\/P0430 DTCs, restricts post-manifold exhaust velocity, and causes elevated engine bay thermal load due to excessive exhaust backpressure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis left and right bank catalytic converter assembly features a high-grade stainless steel shell and direct-fit tubing engineered to withstand thermal cycling without cracking. Inside, an advanced ceramic substrate is coated with a high-efficiency precious metal washcoat to effectively convert hydrocarbons, carbon monoxide, and NOx into inert emissions. Laser-cut mounting flanges and pre-positioned, precision-threaded oxygen sensor bungs line up directly with factory downstream piping, eliminating the need for cutting or custom welding during install.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 × Direct-Fit Catalytic Converters (Left \u0026amp; Right Banks)\u003c\/li\u003e\n  \u003cli\u003eInstallation Accessories\u003c\/li\u003e\n\u003c\/ul\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;\"\u003e2006-2008 BMW 7 Series\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;\"\u003eN62B48 4.8L V8 \/ E65, E66\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;\"\u003e360 hp \/ 360 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\u003e2006 BMW 750i (4.8L V8 - Left \u0026amp; Right)\u003c\/li\u003e\n  \u003cli\u003e2006 BMW 750Li (4.8L V8 - Left \u0026amp; Right)\u003c\/li\u003e\n  \u003cli\u003e2007 BMW 750i (4.8L V8 - Left \u0026amp; Right)\u003c\/li\u003e\n  \u003cli\u003e2007 BMW 750Li (4.8L V8 - Left \u0026amp; Right)\u003c\/li\u003e\n  \u003cli\u003e2008 BMW 750i (4.8L V8 - Left \u0026amp; Right)\u003c\/li\u003e\n  \u003cli\u003e2008 BMW 750Li (4.8L V8 - Left \u0026amp; Right)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the E65\/E66 7 Series?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2006-2008 BMW 7 Series equipped with the \u003cstrong\u003eN62B48\u003c\/strong\u003e 4.8L V8 engine. \u003cstrong\u003eNote: This part is EPA 49-state\/46-state compliant and cannot be shipped to or registered in California, New York, Colorado, or Maine.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eIs an ECU flash or tune required after installation?\u003c\/h4\u003e\n\u003cp\u003eNo tuning is required, as the direct-fit ceramic substrate and factory O2 sensor bung placement allow OEM secondary oxygen sensors to properly read catalyst efficiency without throwing false CEL codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-output European V8 applications, these direct-fit converters match OE emissions flow rates and mounting geometry, ensuring reliable, CEL-free performance without sacrificing exhaust refinement.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67916760940792,"sku":"DS-EQ2P7CRI6","price":289.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-bmw-750li-750i-2006-2008-4-8l-left-right-1.jpg?v=1793477841","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-bmw-750li-750i-2006-2008-4-8l-left-right","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
