The mild steel tubing thins over thermal cycles, leading to structural perforation, blown two-bolt flange gaskets, and cabin exhaust drone. In addition, internal baffles within the aged stock silencer frequently break loose, choking exhaust velocity from the naturally aspirated boxer engine and triggering downstream NVH issues.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from upgraded \u003cstrong\u003eSUS201 stainless steel\u003c\/strong\u003e, this comprehensive replacement assembly counters road brine, moisture accumulation, and aggressive thermal expansion. The mandrel-bent intermediate piping maintains smooth exhaust gas scavenge characteristics without necking down cross-sectional area. Integrated heavy-duty direct-fit mounting hangers align precisely with factory rubber isolators, while precision-machined flanges mate to original catalytic converter outlets. The tuned inline resonator preserves boxer exhaust cadence without cabin drone, restoring correct backpressure for the \u003cstrong\u003eEJ251\u003c\/strong\u003e valvetrain.\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;\"\u003e2000-2004 Subaru Outback, Legacy (2.5L Only)\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\u003eEJ251\u003c\/strong\u003e \/ \u003cstrong\u003eBE \/ BH\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;\"\u003e165 hp \/ 166 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;\"\u003e\n\u003cstrong\u003e2102-97972\u003c\/strong\u003e, \u003cstrong\u003e4-2103-49861\u003c\/strong\u003e, \u003cstrong\u003e4-2103-49863\u003c\/strong\u003e, \u003cstrong\u003e56044\u003c\/strong\u003e, \u003cstrong\u003e54319\u003c\/strong\u003e, \u003cstrong\u003e6-2102-49859\u003c\/strong\u003e, \u003cstrong\u003e608455\u003c\/strong\u003e, \u003cstrong\u003e7485\u003c\/strong\u003e, \u003cstrong\u003e68454\u003c\/strong\u003e, \u003cstrong\u003e7437\u003c\/strong\u003e, \u003cstrong\u003eSU7205\u003c\/strong\u003e, \u003cstrong\u003e7217\u003c\/strong\u003e, \u003cstrong\u003eSU7207\u003c\/strong\u003e, \u003cstrong\u003eSU7307\u003c\/strong\u003e, \u003cstrong\u003eSU7347\u003c\/strong\u003e, \u003cstrong\u003eSU7357\u003c\/strong\u003e\n\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\u003e2000-2004 Subaru Outback 2.5L H4 AWD (BH Chassis)\u003c\/li\u003e\n  \u003cli\u003e2000-2004 Subaru Legacy 2.5L H4 AWD\/FWD (BE\/BH Chassis)\u003c\/li\u003e\n  \u003cli\u003eFits naturally aspirated 2.5L SOHC EJ25 models only; does not fit 3.0L H6 EZ30 models.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the BE \/ BH Outback, Legacy?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-on fit for the 2000-2004 Subaru Outback and Legacy equipped with the \u003cstrong\u003eEJ251\u003c\/strong\u003e 2.5L boxer engine.\u003c\/p\u003e\n\n\u003ch4\u003eDoes this exhaust replacement require ECU tuning or welding?\u003c\/h4\u003e\n\u003cp\u003eNo welding or ECU recalibration is required; the kit utilizes OEM-style bolt-on flanges, mounting brackets, and included gaskets for factory-location service.\u003c\/p\u003e\n\n\u003ch3\u003eThe Subaru Boxer Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe duty cycles and rough terrain, this replacement exhaust restores signature boxer engine sound isolation and corrosion-resistant reliability to your all-wheel-drive powertrain.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67530933698808,"sku":"DS-EKARBTG97","price":311.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-muffler-kit-for-subaru-outback-legacy-2000-2004-2-5l-1.jpg?v=1790525362","url":"https:\/\/performancechiptuning.com\/fr\/products\/exhaust-muffler-kit-for-subaru-outback-legacy-2000-2004-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
