Upgrade from the stock B48 downpipe to the MAD B48 catless downpipe for maximum airflow, power, and sound!
Upgrade to the MAD BMW B48 downpipe to eliminate the backpressure caused by your stock catalytic converters. By upgrading to our downpipe, your turbo can now spool faster and achieve maximum power. As a bonus, your car will sound a lot nicer as well.
