{"product_id":"r-11-full-exhaust-system","title":"R-11 Full Exhaust System","description":"The Yoshimura R-11 Race Series full exhaust system is engineered for competition use, offering a substantial performance upgrade for your motorcycle. Crafted from durable stainless steel, this system provides a significant weight savings of 4.3kg compared to the stock exhaust.\n\nThis full system delivers impressive performance gains, with a reported increase of +14.6% in power and +14.6% in torque, both achieved at 6,400rpm. It can produce up to 104.0dB at 5,000rpm without the supplied dB killer, and 101.0dB with it installed. However, it is crucial to note that this product is explicitly designed and intended for closed-course competition use only and is not street legal. Use on public roads or land is prohibited by federal and state regulations.\n\nInstallation of this system requires careful consideration. Yoshimura recommends remapping the ECU to achieve optimal performance, especially when frequently using the high-rpm range or riding on a race track.","brand":"Yoshimura","offers":[{"title":"Default Title","offer_id":52664156684600,"sku":"170-196-5F50","price":1141.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687544055.jpg?v=1784334282","url":"https:\/\/store.motormia.co\/products\/r-11-full-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
