High-mileage Duratec engines expose the stock core to carbon fouling and thermal fatigue, causing restricted backpressure, sluggish low-end response, and recurring emissions check-engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from a heavy-gauge 409 stainless steel converter body mated to aluminized, mandrel-bent exhaust piping to resist corrosion and structural fracture. Precision OE-spec flanges and integrated hangers allow direct bolt-on installation without cutting or welding. Internal high-flow washcoat substrates maintain optimal catalytic reduction while reducing parasitic backpressure.\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;\"\u003e2009-2011 Mercury Mariner 2.5L\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;\"\u003e2.5L Duratec 25 \/ Ford CD2\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;\"\u003e171 hp \/ 171 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;\"\u003e16499, 645273, 30572, 19546\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009 Mercury Mariner Base, Premier (2.5L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2010 Mercury Mariner Base, Premier (2.5L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2011 Mercury Mariner Base, Premier (2.5L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e\u003cem\u003eNote: EPA Federal emissions compliant.
