{"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":45545991733292,"sku":"GFB5701","price":40.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0569\/8787\/7420\/files\/2ed51a5a-6808-4fce-b005-25b6a15ef358-800_2777abb3-f8bc-44d8-9010-9a08201e8613.jpg?v=1778860273","url":"https:\/\/performance.shiftcultureofficial.com\/products\/gfb-whistling-trumpet-only-for-stealth-fx-and-wrx-hybrid","provider":"Shift Culture Performance ","version":"1.0","type":"link"}
