BMW X3M X4M COMPETITION DECAT DOWNPIPES | MTC MOTORSPORT

• BMW X3M F97 2019+
• BMW X4M F98 2019+

We have tested this product and found increases of 30-40bhp on a standard car.

These downpipes fit the stock catback as well as all aftermarket catbacks that match up with the OEM downpipe.

Professional installation is recommended as some exhausts sit slightly different from others and can be tight. You may also need to code out the new PPF filters on some of the newer cars.
