{"product_id":"gfb-whistling-trumpet-only-for-stealth-fx-and-wrx-hybrid","title":"GFB Whistling Trumpet (only for Stealth FX and WRX Hybrid)","description":"The 5701 can be used in place of the standard trumpet on GFB valves (Part numbers T9003 \u0026amp; T9503), and will make a whistling sound. However, it is necessary to run the valve so that all (or most) of the air vents through the trumpet ? Respons valves will typically not generate the velocity required to whistle when set to 50\/50 venting.","brand":"Go Fast Bits","offers":[{"title":"Default Title","offer_id":42271976652894,"sku":"GFB5701","price":53.69,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/9411\/7726\/files\/2ed51a5a-6808-4fce-b005-25b6a15ef358-800_0f8357ad-a3ca-49f7-8f30-4469f211f4c8.jpg?v=1765516875","url":"https:\/\/bmrksi-iy.myshopify.com\/products\/gfb-whistling-trumpet-only-for-stealth-fx-and-wrx-hybrid","provider":"Wegaparts.com","version":"1.0","type":"link"}
