The high-flow cat outflows the stock unit significantly while maintaining emissions compliance in most states outside California. The divorced wastegate design is a genuine performance benefit over a standard integrated WG downpipe — not just a design feature. A tune is not optional with this installation — running any aftermarket downpipe on the stock ECU calibration is a reliability concern, not just a performance one.\u003c\/p\u003e\n\n\u003ch4\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInvidia Catted Downpipe with Divorced Wastegate\u003c\/li\u003e\n  \u003cli\u003eHigh-flow catalytic converter\u003c\/li\u003e\n  \u003cli\u003eNew exhaust gasket and hardware\u003c\/li\u003e\n  \u003cli\u003eNOTE: Does not include turbo-to-downpipe gasket — source separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003e\u003cstrong\u003eAbout Invidia\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eInvidia is a Taiwanese performance exhaust manufacturer with a strong following in the Subaru, Mitsubishi, and Japanese sports car communities. Their catalog covers cat-back exhausts, downpipes, headers, manifolds, and full exhaust systems built around SUS304 stainless steel construction with CNC-machined flanges and direct OEM fitment. Invidia exhausts are among the most widely installed aftermarket systems on Subaru platforms globally — well-documented, well-supported, and proven across thousands of street and track builds. Subispeed carries the full Invidia lineup because their combination of quality construction, fitment accuracy, and range of tip and finish options makes them the exhaust brand we recommend to Subaru owners at nearly every power level.\u003c\/p\u003e\n\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2008-2014\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX\u003c\/td\u003e\n\u003ctd\u003eEJ255 MT\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2008-2020\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX STI\u003c\/td\u003e\n\u003ctd\u003eEJ257 MT\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2005-2009\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eLegacy GT\u003c\/td\u003e\n\u003ctd\u003eEJ255 MT — manual only\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2009-2013\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eForester XT\u003c\/td\u003e\n\u003ctd\u003eEJ255\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2005-2009\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eOutback XT\u003c\/td\u003e\n\u003ctd\u003eEJ255 MT\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Invidia","offers":[{"title":"Default Title","offer_id":45712805560406,"sku":"INVHS08SW1DOC","price":269.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/0411\/1190\/files\/2yizzsaesbvn_59ced8e7-e57e-4dc8-9311-6c08e4d7037b.jpg?v=1788785057","url":"https:\/\/truegearus.com\/products\/invidia-catted-downpipe-divorced-wastegate-w-2-bungs-subaru-models-inc-2008-2014-wrx-2008-2021-sti-14d8c2","provider":"TrueGear","version":"1.0","type":"link"}
