{"product_id":"ej25-2-bolt-up-pipe","title":"EJ25 2-Bolt Up-Pipe","description":"The GrimmSpeed 2-Bolt Up-Pipe is a performance-oriented component engineered to enhance the responsiveness of EJ25 engines equipped with an OEM-style 2-bolt header. Developed in-house using advanced CAD software and a FARO Arm, this up-pipe ensures precise fitment. It is constructed from robust 14-gauge 304 stainless steel tubing, noted as being 33% thicker than many competing products, and features 1\/2\" CNC-milled 304 stainless steel flanges for tight tolerances. The flex joint is made of durable 321 stainless steel with an interlocking liner, and the pipe is CNC mandrel bent for smooth flow. The flanges are hand-welded both inside and outside for superior strength and a smooth mating surface.\n\nThis up-pipe is designed to significantly reduce turbo lag, with expected improvements in spool times of approximately 300-400 RPM. This results in faster turbo engagement and more efficient power delivery, particularly beneficial in performance and track applications. The product is SEMA Certified and CARB Certified for listed fitments.\n\nInstallation includes everything needed, such as GrimmSpeed Fire Ring multi-layer steel gaskets and corrosion-resistant zinc-coated hardware. It is available in two finishes: raw stainless steel or a black ceramic thermal coating, which helps reduce engine bay temperatures and prevent heat soak.\n\nFitment is specifically for USDM Subaru EJ25 engines with a 2-bolt header configuration, including the 2004-2021 Subaru STI, 2006-2014 Subaru WRX, 2006-2013 Subaru Forester XT, 2007-2009 Subaru Legacy GT, and 2007-2009 Subaru Outback XT. A tune is not required for installation and operation.","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":52664225726776,"sku":"003002","price":245.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687547657.jpg?v=1784335483","url":"https:\/\/store.motormia.co\/products\/ej25-2-bolt-up-pipe","provider":"MOTORMIA","version":"1.0","type":"link"}
