The factory setup was replaced with a precision built BMW 4 Series Exhaust System using 304L aircraft grade stainless steel, improving durability while delivering a cleaner and more purposeful sound.\n\nThis BMW 4 Series Exhaust Upgrade resolved the restrictive flow of the original system, enhancing throttle response and giving the vehicle a stronger road presence without unwanted drone. Multiple configuration options allowed us to tailor the sound profile perfectly, resulting in a well balanced BMW 4 Series Exhaust that looks sharper, sounds richer, and performs exactly as expected.","brand":"BMW","offers":[{"title":"Default Title","offer_id":55246749696342,"sku":null,"price":658.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0937\/5829\/2310\/files\/65_Newcs.png?v=1788802895","url":"https:\/\/dkuperformance.co.uk\/products\/cat-back-exhaust-bmw-4-series-435d-xdrive-f32-f33-f36-2013-2020","provider":"DKU Performance","version":"1.0","type":"link"}
