Ideally suited for 50cc and 70cc sports \u0026amp; mid-race and racing cylinders; definitely the go-to muffler for 70cc tuning.To avoid vibrations, the stainless steel mount is double rubber mounted, and does its job really well.in order for the YASUNI R to be street-legal, the headpipe and silencer are equipped with restrictors. If run with the original cylinder, performance is similar to the original exhaust, only with a throatier sound. When removing the restrictors, the exhaust loses road approval, but can unfold its full potential.Conclusion:The YASUNI R has a very wide power band and is really quiet, but with a very throaty sound. The silencer can be replaced to visually adapt the exhaust to your scooter. As with expensive racing systems, the mufflers are spring-loaded, which makes leaking virtually impossible.To get the most out of this exhaust you should use it with a 17,5mm carburetor (minimum) and a tuning CVT.Technical data:Material body: sheet steelMaterial bracket: stainless steelMaterial silencer: ALUColour silencer: blackWith road approval \/ homologation \/ E-passFor Minarelli vertical (Yamaha Slider, BWs etc.) Questions about the product Downloads and Media Data sheetInstallation guide\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: Yasuni\u003c\/li\u003e\n\u003cli\u003eSKU: YAS307B\u003c\/li\u003e\n\u003cli\u003eAvailability: In stock\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yasuni","offers":[{"title":"Default Title","offer_id":53461504622935,"sku":"YAS307B","price":313.43,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/4027\/5287\/files\/695243_6336221.jpg?v=1777841419","url":"https:\/\/mattmoto.pl\/en\/products\/exhaust-yasuni-r-black-minarelli-vertical-road-legal-yas307b","provider":"MattMoto Skutery","version":"1.0","type":"link"}
