Over extended mileage, the original ceramic matrix breaks down, creating restricted flow channels, unmetered pre-cat exhaust leaks at the pressed flange joints, and persistent check engine lights. This thermal fatigue increases backpressure against the cylinder heads, raising exhaust gas temperatures and choking mid-range torque.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed with durable tubular stainless steel, this replacement assembly resists high-heat oxidation and stress cracking. The core houses a high-efficiency ceramic substrate loaded with precious metal washcoats to ensure optimal emissions reduction without impeding exhaust velocity. Featuring precision-cut, heavy-gauge mounting flanges and integrated O2 sensor bungs, it mounts directly to the cylinder exhaust ports for an airtight seal that withstands constant engine vibration.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × Direct-Fit Front Catalytic Converter Manifold Assembly\u003c\/li\u003e\n  \u003cli\u003eInstallation Hardware and Gasket Accessories\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;\"\u003e2006-2007 Subaru Impreza\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\u003eEJ253\u003c\/strong\u003e \/ \u003cstrong\u003eGD, GG\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;\"\u003e173 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;\"\u003e674-864, 4096-1854, 44620-AB620, 44620-AA970, 44620-AC07A, 44620-AC750, 44620AC750, 0961856, 642803, 674864, 096-1854, 18265, 73050, 16564, 44620AA0, 40859, 58285\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\u003e2006-2007 Subaru Impreza 2.5i Sedan 2.5L (GD)\u003c\/li\u003e\n  \u003cli\u003e2006-2007 Subaru Impreza 2.5i Wagon 2.5L (GG)\u003c\/li\u003e\n  \u003cli\u003e2006 Subaru Impreza Outback Sport Wagon 2.5L (GG)\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 GD\/GG Impreza?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2006-2007 Subaru Impreza equipped with the naturally aspirated \u003cstrong\u003eEJ253\u003c\/strong\u003e engine. \u003cstrong\u003eThis component does not fit turbocharged WRX or STI models (EJ255\/EJ257) and is not legal for sale or use in California, New York, Colorado, or Maine emissions applications.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eAre new oxygen sensor ports provided in factory locations?\u003c\/h4\u003e\n\u003cp\u003eYes, this assembly features precision-welded O2 sensor bungs positioned in factory locations to retain proper air-fuel feedback without extending sensor wiring.\u003c\/p\u003e\n\n\u003ch3\u003eThe Subaru Performance Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve your boxer engine's signature exhaust note, smooth power delivery, and emissions integrity with robust stainless construction designed to handle daily commuter abuse and high-RPM heat cycling.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67563062821112,"sku":"DS-EU0OB2HNK","price":154.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-subaru-impreza-2006-2007-2-5l-front-1.jpg?v=1791000134","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-subaru-impreza-2006-2007-2-5l-front","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
