{"product_id":"4-high-flow-cat-downpipe","title":"4\" High-Flow Cat Downpipe","description":"The CTS Turbo 4\" High-Flow Cat is engineered to significantly improve exhaust flow and unleash the performance potential of your BMW N55 engine equipped with an electric wastegate. Constructed from premium T304 stainless steel, this downpipe features precise, hand TIG welding with back-purging to ensure a robust and long-lasting build.\n\nHowever, it is explicitly intended for OFF-ROAD use only.
