Show original supplier description
This genuine BMW Rear Muffler is engineered as a direct replacement for specific X3 and X4 models. It is designed for the X3 35i series manufactured from April 2013 and onwards, as well as the X4 35i series equipped with the 3.0L engine. This part is a direct substitute for the older part number 18308604209, ensuring a seamless fit and restoration of your vehicle's original exhaust system. As a genuine OEM part, this rear muffler is manufactured to BMW's exacting standards, promising the same quality, performance, and durability as the original component. Please note that while this part is listed for 2013-2017 BMW X3 and X4 models, it specifically applies to the 35i series with the 3.0L engine and requires a production date from April 2013 for the X3. Always verify fitment with your vehicle's VIN to ensure compatibility.
