Over extended mileage, unburned hydrocarbons and high exhaust gas temperatures cause internal ceramic washcoat degradation and substrate melt-down. Additionally, thermal expansion leads to hairline cracking at the factory manifold transitions and flex joints, inducing exhaust leaks, false downstream oxygen sensor readings, reduced fuel economy, and persistent check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 3-piece assembly—encompassing the front left, front right (radiator and firewall banks), and rear underfloor units with an integrated flex pipe—features mandrel-bent, high-grade stainless steel tubing for uniform wall thickness and corrosion resistance. High-flow ceramic substrates loaded with washcoat precious metals promote rapid light-off and efficient catalytic conversion without choking high-RPM gas velocity. Heavy-gauge flanges and automated TIG welds prevent exhaust leaks, mating directly to stock exhaust manifolds and cat-back piping without cutting or custom fabrication.\u003c\/p\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;\"\u003e2009-2017 Buick Enclave\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;\"\u003e3.6L V6 (LLT \/ LFX) \/ Lambda\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;\"\u003e288 hp \/ 270 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;\"\u003e16709, 16710, 50484, 16574\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\u003e2009-2017 Buick Enclave Base 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2009-2017 Buick Enclave CX 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2009-2017 Buick Enclave CXL 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2014-2017 Buick Enclave Convenience 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2014-2017 Buick Enclave Leather 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2014-2017 Buick Enclave Premium 3.6L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the Lambda Enclave?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2017 Buick Enclave equipped with the 3.6L High Feature V6 engine.\u003c\/p\u003e\n\n\u003ch4\u003eWill this unit clear downstream catalyst efficiency codes (P0420\/P0430)?\u003c\/h4\u003e\n\u003cp\u003eYes, the OE-grade ceramic core restores OEM-level reduction and oxidation efficiency to clear P0420 and P0430 DTCs provided underlying misfires or sensor issues are resolved.\u003c\/p\u003e\n\n\u003ch3\u003eThe Buick Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained highway cruising and passenger-load thermal stresses, this direct-fit stainless assembly ensures structural durability, leak-free cabin isolation, and reliable emissions compliance for the life of your luxury crossover.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67537676468472,"sku":"DS-EF9RBI6BD","price":239.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-buick-enclave-2009-2017-3-6l-front-left-right-rear-1.jpg?v=1790613775","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-buick-enclave-2009-2017-3-6l-front-left-right-rear","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
