The ProX kit just replaces the OEM valves \u0026amp; valve springs and can be installed using the OEM retainers, bases and valve seals.","brand":"PROX","offers":[{"title":"EXHAUST VALVE CONVERSION SET TI-STEEL KAW (28.SES4409-1)","offer_id":50490977714219,"sku":"28.SES4409-1","price":166.95,"currency_code":"USD","in_stock":true},{"title":"EXHAUST VALVE CONVERSION SET TI-STEEL KAW\/SUZ (28.SES4335-1)","offer_id":50490977746987,"sku":"28.SES4335-1","price":155.95,"currency_code":"USD","in_stock":true},{"title":"EXHAUST VALVE CONVERSION SET TI-STEEL SUZ (28.SES3407-1)","offer_id":50490977779755,"sku":"28.SES3407-1","price":157.34,"currency_code":"USD","in_stock":false},{"title":"EXHAUST VALVE CONVERSION SET TI-STEEL SUZ (28.SES3338-1)","offer_id":50490977812523,"sku":"28.SES3338-1","price":155.95,"currency_code":"USD","in_stock":true},{"title":"EXHAUST VALVE CONVERSION SET TI-STEEL GAS\/YAM (28.SES2424-1)","offer_id":50490977845291,"sku":"28.SES2424-1","price":143.95,"currency_code":"USD","in_stock":true},{"title":"EXHAUST VALVE CONVERSION SET TI-STEEL GAS\/YAM (28.SES2402-1)","offer_id":50490977878059,"sku":"28.SES2402-1","price":155.95,"currency_code":"USD","in_stock":true},{"title":"EXHAUST VALVE CONVERSION SET TI-STEEL YAM (28.SES2414-1)","offer_id":50490977910827,"sku":"28.SES2414-1","price":155.95,"currency_code":"USD","in_stock":true},{"title":"EXHAUST VALVE CONVERSION SET TI-STEEL HUSQ\/KTM (28.SES6351-1)","offer_id":50490977943595,"sku":"28.SES6351-1","price":155.95,"currency_code":"USD","in_stock":true},{"title":"EXHAUST VALVE CONVERSION SET TI-STEEL HUS\/HUSQ\/KTM (28.SES6353-1)","offer_id":50490977976363,"sku":"28.SES6353-1","price":155.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0017\/9568\/6464\/files\/8b74-572a590e6f9c7.jpg?v=1792113673","url":"https:\/\/evolution-motorcycles.com\/products\/prox-steel-valve-exhaust-kit","provider":"Evolution Motorcycles","version":"1.0","type":"link"}
