The product is built to order in North Carolina, with an estimated ship window of 4-6 weeks. Optional Jet-Hot ceramic coatings are available in various finishes to further enhance heat management and aesthetics.","brand":"Kooks","offers":[{"title":"Default Title","offer_id":52686522089784,"sku":"11542300","price":2546.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/658754314.jpg?v=1784874587","url":"https:\/\/store.motormia.co\/products\/1-3-4-x-1-7-8-x-3-ss-stepped-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
