The \u003cstrong\u003e5702\u003c\/strong\u003e is a refined take on the original trumpet, engineered to deliver that signature whistle on setups that don't generate enough boost or RPM to trigger the standard part.\u003c\/p\u003e\n\n\u003cp\u003eThis listing covers the \u003cstrong\u003e5702 Whistling Trumpet\u003c\/strong\u003e, designed as a drop in replacement for the stock trumpet fitted to \u003cstrong\u003eRespons\u003c\/strong\u003e and \u003cstrong\u003eDeceptor Pro II\u003c\/strong\u003e valves. It produces the whistle more easily than the original \u003cstrong\u003e5701\u003c\/strong\u003e trumpet and at a slightly higher pitch, making it better suited to lower boost applications where the 5701 struggles to sing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e This trumpet is not compatible with the \u003cstrong\u003eT9003\u003c\/strong\u003e or \u003cstrong\u003eT9503\u003c\/strong\u003e valve types. For the whistle to work properly, the valve needs to be set so most or all air vents through the trumpet — Respons valves running 50\/50 venting typically won't generate enough velocity to whistle.\u003c\/p\u003e\n\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModified trumpet profile for low boost whistle response\u003c\/li\u003e\n\u003cli\u003eSlightly higher pitch than the original 5701 trumpet\u003c\/li\u003e\n\u003cli\u003eDirect replacement for the stock trumpet on compatible GFB valves\u003c\/li\u003e\n\u003cli\u003eSimple bolt on fitment, no modification required\u003c\/li\u003e\n\u003cli\u003eExcludes T9003 and T9503 valve types\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\n\u003ch3\u003eVehicle Fitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSuits Response\/Deceptor Pro BOV\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003ePlease confirm your GFB valve model before ordering, as this trumpet is not suited to every GFB BOV type.\u003c\/em\u003e\u003c\/p\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":67799879516464,"sku":"5702","price":41.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/3156\/2544\/files\/5702_7a89bc5b-4f37-42bf-9379-481e054f201f.jpg?v=1789614233","url":"https:\/\/coore.com.au\/products\/gfb-whistling-trumpet-response-deceptor-pro-bov","provider":"Coore | Performance \u0026 Aftermarket","version":"1.0","type":"link"}
