Typical boxer ring wear and oil blow-by through the PCV circuit foul the dense OEM ceramic matrix, drastically choking flow along Bank 2 (Front Left). This backpressure spike causes exhaust gas recirculation inefficiencies, reduces volumetric efficiency, dulls throttle tip-in, and triggers persistent check engine lights (DTC P0420\/P0430).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-on manifold catalyst, this unit features a robust stainless steel outer shell designed to withstand thermal cycling and underbody corrosion. Inside, an advanced ceramic honeycomb monolith is washcoated with high-grade precious metals to accelerate catalytic reduction and oxidation reactions without restricting exhaust gas velocity. Precision laser-cut flanges, accurate oxygen sensor bungs, and mandrel-formed inlet\/outlet geometries bolt directly to OEM mounting locations, eliminating exhaust leaks and eliminating the need for cutting, welding, or 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; margin-bottom: 20px;\"\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;\"\u003e2010-2019 Subaru Legacy, Outback (Front Left)\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;\"\u003e\n\u003cstrong\u003eEZ36D\u003c\/strong\u003e 3.6L H6 \/ \u003cstrong\u003eBM, BR, BN, BS\u003c\/strong\u003e\n\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;\"\u003e256 hp \/ 247 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\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2010-2019 Subaru Legacy 3.6R (Sedan, 3.6L H6 EZ36D)\u003c\/li\u003e\n  \u003cli\u003e2010-2019 Subaru Outback 3.6R (Wagon, 3.6L H6 EZ36D)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the BM, BR, BN, and BS Legacy and Outback?\u003c\/strong\u003e\u003cbr\u003eYes, this catalytic converter is a direct bolt-in fitment for all 2010-2019 \u003cstrong\u003eBM\/BR\u003c\/strong\u003e (5th gen) and \u003cstrong\u003eBN\/BS\u003c\/strong\u003e (6th gen) chassis equipped with the 3.6L \u003cstrong\u003eEZ36D\u003c\/strong\u003e flat-six engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this catalytic converter legal for road use in California?\u003c\/strong\u003e\u003cbr\u003eNo, this assembly is an EPA-compliant federal catalytic converter and is not legal for sale, installation, or use in California or CARB-compliant states.\u003c\/p\u003e\n\n\u003ch3\u003eThe Subaru Boxer Caliber\u003c\/h3\u003e\n\u003cp\u003eSubaru's symmetrical AWD and horizontally opposed flat-six layout demand balanced exhaust backpressure across both cylinder banks.
