{"product_id":"yonristic-performance-cat-back-exhaust-system-2","title":"Yonristic Performance Cat-Back Exhaust System","description":"The Yonristic Performance cat-back exhaust system is designed for the BMW Z4 M40i (G29) 2019-Present models with the B58 3.0L Turbocharged Inline-6 Engine. This system features a full 3.5-inch high-flow midpipe that transitions into dual 2.75-inch pipes through a precision-cast Y-collector, aimed at reducing backpressure and improving exhaust flow.\n\nIt includes a true quad-tip rear section designed to enhance the Z4's aesthetics and deliver a more exotic, performance-oriented tone. The exhaust integrates seamlessly with the OEM valve control, offering a comfortable driving experience that becomes more aggressive when the valves are opened. Constructed from AISI 304 stainless steel, this system is built for performance and compatibility with future modifications like ECU tunes or upgraded downpipes, without introducing drone or harshness.","brand":"Yonristic Performance","offers":[{"title":"Default Title","offer_id":53709310656824,"sku":"YR-7097-YON-CAT","price":2230.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/820302633.webp?v=1793534049","url":"https:\/\/store.motormia.co\/products\/yonristic-performance-cat-back-exhaust-system-2","provider":"MOTORMIA","version":"1.0","type":"link"}
