Unleash the true performance and sound of your BMW M3 with the M. Flow Sport Series Cat-Back Exhaust System, engineered for the 2001–2006 3.2L models. Designed to deliver aggressive performance and head-turning style, this system is built to make your M3 stand out.
 
Featuring 2.25-inch mandrel-bent piping for optimal airflow, the exhaust flows through dual straight-through mufflers and exits via a bold quad-split rear setup. The system is finished with polished 3-inch double-wall angle-cut tips with folded edges – a sleek, sporty look to match its powerful sound.
 
Dyno-tested and proven, this system delivers M. Flow’s signature exhaust tone – aggressive on the outside with a moderate cabin presence. Please verify local noise regulations before installation.
 
This cat-back system replaces all components from the catalytic converter back, offering improved performance and a deep, refined sound. Built from corrosion-resistant stainless steel and crafted using advanced 3D scanning and robotic CNC manufacturing, it ensures a precise fit and easy bolt-on installation.
