Many times you have asked for a replacement trumpet that gives a different sound, and here it is.  The ability to change the sound of a blow-off valve is increasingly becoming an important issue with buyers, who want to sound different from everyone else.\u003cbr\u003e\u003cbr\u003eIn 2004, GFB released the Whistling Trumpet (part # 5701), which emitted a piercing screech when driving aggressively. Unfortunately for a number of GFB owners, the 5701 trumpet only worked with some valve types.\u003cbr\u003e\u003cbr\u003eFor the owners of all other types of GFB valves, GFB have now released the 5702  a modified version of the Whistling Trumpet that is designed to work on low boost applications where the 5701 doesnt cut it.\u003cbr\u003e\u003cbr\u003eThe 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch. Like the 5701 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.\u003cbr\u003e\u003cbr\u003eThis part is recommended for Respons and Deceptor Pro II valves EXCLUDING T9003 \u0026amp; T9503","brand":"Bapcor","offers":[{"title":"Default Title","offer_id":47455521472765,"sku":"SBX-P6888716","price":79.56,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/8396\/7485\/files\/5701_web.jpg?v=1777191104","url":"https:\/\/krenbits.com\/products\/sb-gfb-whistling-trumpet-5702","provider":"Kren Bits","version":"1.0","type":"link"}
