Show original supplier description
Introducing the MAD X3M X4M Axle-Back Exhaust System, engineered to elevate the driving experience of your BMW X3M or X4M. Crafted with precision and passion, this exhaust system delivers a thrilling blend of performance, sound, and style. Designed for seamless compatibility, the MAD X3M X4M Axle-Back Exhaust System can be effortlessly paired with either the MAD Single Midpipe (no cutting required) or the factory midpipe (cutting required), providing flexibility and customization options. Experience an enhanced exhaust note that resonates with authority, while enjoying improved exhaust flow for maximum efficiency. This axle-back exhaust features 4.1-inch (101mm) tips and retains the stock exhaust valve actuators, meaning the operation of the exhaust valve is unchanged and the exhaust tone can still be adjusted via the M-drive settings. Computer-controlled exhaust valves are retained to limit noise during low-speed driving and open fully during high-load conditions. Drone abatement technologies are integrated to reduce cabin resonance, ensuring a pleasingly louder, sportier sound without unwanted noise. The MAD X3M X4M Axle-Back Exhaust System is specifically designed for the 2019-2023 BMW X3M F97 and 2019-2023 BMW X4M F98 models, including the Competition variants with the S58 3.0L engine. It offers factory-like fitment with included mounting hardware.
