This dense matrix creates acute backpressure, severely constricting exhaust gas scavenging, delaying boost threshold, and trapping extreme radiant heat directly within the engine bay and hot-vee valley under sustained high load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for maximum flow efficiency, these downpipes utilize high-grade mandrel-bent stainless steel and integrated thermal heat shields to suppress radiant under-hood heat transfer. Featuring an enlarged ~115 mm inlet transition tapering smoothly to match the downstream exhaust architecture, exhaust gas velocity is dramatically increased. The internal 200-cell high-flow metallic substrate significantly reduces exhaust restriction compared to factory ceramic cores without running fully catless. Precision TIG-welded mounting flanges mate seamlessly to factory turbo outlet flanges for a leak-free, direct bolt-on installation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Pair Stainless Steel High-Flow 200-Cell Catted Downpipes with Integrated Heat Shields\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;\"\u003e2018-2024 Lamborghini Urus\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;\"\u003eEA825 4.0L Twin-Turbo V8 \/ Type 636\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;\"\u003e641 hp \/ 627 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\u003e2018-2024 Lamborghini Urus 4.0L Twin-Turbo V8\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 Type 636 Urus?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-on fit for the 2018-2024 Lamborghini Urus equipped with the \u003cstrong\u003eEA825\u003c\/strong\u003e 4.0L twin-turbo V8 engine.\u003c\/p\u003e\n\n\u003ch4\u003eIs an ECU tune required following installation?\u003c\/h4\u003e\n\u003cp\u003eWhile physically bolt-on, an ECU recalibration is strongly recommended to optimize fueling, maximize boost spool dynamics, and prevent secondary oxygen sensor catalyst efficiency trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Lamborghini European Engineering Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand the demanding thermal and gas flow thresholds of modern twin-turbo European platforms, this downpipe configuration delivers optimal thermal protection, precise OEM flange fitment, and robust stainless steel durability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67558888145144,"sku":"DS-E1I8JV0JZ","price":1515.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-catted-downpipes-for-lamborghini-urus-2018-2024-4-0l-1.jpg?v=1790925533","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-catted-downpipes-for-lamborghini-urus-2018-2024-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
