{"product_id":"respons-tms-blow-off-valve","title":"Respons TMS Blow-Off Valve","description":"Unlike many dual-port blow-off valves, the Respons features GFB's patented venting bias adjustment system. This allows users to precisely control the ratio of air vented to atmosphere versus recirculated, enabling customization of the blow-off sound from silent operation to maximum noise.\n\nThe valve's design prevents it from being forced open by high boost levels, a common issue with other valves. Its balanced piston design uses boost pressure on both sides to cancel forces, ensuring all boost is delivered to the engine regardless of pressure. GFB's Turbo Management System (TMS) principle means the valve is shut until required to open, differing from factory bypass valves that remain open until closure is necessary.\n\nIt aims to provide the desired blow-off sound without causing common issues like stalling or backfiring, even on sensitive MAF-based systems.\n\nApplications include 2015-2021 Subaru WRX STi, 2004-2014 Subaru Impreza WRX STi, 2002-2007 Subaru Impreza WRX, and 2005-2008 Subaru Forester XT.","brand":"GFB (Go Fast Bits)","offers":[{"title":"Default Title","offer_id":52688550625592,"sku":"T9003","price":275.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687901434.jpg?v=1784890866","url":"https:\/\/store.motormia.co\/products\/respons-tms-blow-off-valve","provider":"MOTORMIA","version":"1.0","type":"link"}
