This flex section degrades over time ,  it cracks, leaks exhaust gases, and creates a boost leak that reduces turbo efficiency and generates annoying rattling. Beyond the reliability issue, the flex section is a genuine flow restriction in the pre-turbo exhaust path. GrimmSpeed's 2-bolt stainless up-pipe eliminates both problems.\u003c\/p\u003e\n\n\u003cdiv style=\"clear:both;\"\u003e\u003c\/div\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0754\/6748\/9554\/files\/GRM.1099.1.SS-4.jpg?v=1747941021\" alt=\"GrimmSpeed 2-Bolt Up-Pipe (Stainless Steel) - EJ25 Engines (Inc. 2004-2021 Subaru STI  \/ 2006-2014 Subaru WRX)\" style=\"max-width:100%;height:auto;display:block;margin:20px 0;\"\u003e\n\n\u003cp\u003eThe 2-bolt design uses a rigid stainless connection rather than a flex section ,  the mount geometry accommodates engine movement without requiring a flexible section in the pipe.

Everything they make is designed around real-world use ,  their engineers drive the same cars their customers drive, which means product decisions are made with genuine platform knowledge behind them. GrimmSpeed designs parts in-house, sources quality materials, and validates fitment on the actual application before release. The result is parts that install correctly the first time, perform as advertised, and hold up under the conditions Subaru owners actually subject their cars to. Whether it is a critical engine component or a cosmetic upgrade, the same attention to detail and fit quality applies across the catalog.\u003c\/p\u003e\n\n\u003ch4\u003e\u003cstrong\u003eThe RallySport Take\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eIf you own an EJ-series Subaru WRX or STI with meaningful mileage and have not replaced the up-pipe, we recommend doing it sooner rather than later. The factory flex section failure is a when, not an if. The GrimmSpeed stainless up-pipe is the replacement that solves it permanently. Fits the 2004-2021 Subaru WRX STI and 2006-2014 WRX among other EJ25 applications.\u003c\/p\u003e\n\n\u003cdiv style=\"clear:both;\"\u003e\u003c\/div\u003e\n\n\u003ch4\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/h4\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003cth style=\"text-align:left;padding:8px 12px;border:1px solid #ddd;\"\u003eYear\u003c\/th\u003e\n\u003cth style=\"text-align:left;padding:8px 12px;border:1px solid #ddd;\"\u003eMake\u003c\/th\u003e\n\u003cth style=\"text-align:left;padding:8px 12px;border:1px solid #ddd;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"text-align:left;padding:8px 12px;border:1px solid #ddd;\"\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background:#fafafa;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003e2004-2021\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eSubaru\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eWRX STI\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eEJ257\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003e2006-2014\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eSubaru\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eWRX\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eEJ255\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#fafafa;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003e2005-2009\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eSubaru\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eLegacy GT\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eEJ255\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003e2004-2008\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eSubaru\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eForester XT\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #ddd;\"\u003eEJ255\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":45711751086166,"sku":"grmGRM.1099.1.SS","price":86.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/0411\/1190\/files\/9v9jc8rt5jiu_95550bff-c5ac-407e-a6c5-867598c7980b.jpg?v=1788775043","url":"https:\/\/truegearus.com\/products\/grimmspeed-2-bolt-up-pipe-stainless-steel-ej25-engines-inc-2004-2021-subaru-sti-2006-2014-subaru-wrx-apdq0y","provider":"TrueGear","version":"1.0","type":"link"}
