Upgrade from the stock S58 downpipes to the MAD 3.5" Fat Boy S58 catless downpipes for maximum airflow, power, and sound!
Upgrade to the MAD BMW 3.5" Fat Boy S58 downpipes to eliminate the backpressure caused by your stock catalytic converters. By upgrading to our downpipes, your turbos can now spool faster and achieve maximum power. As a bonus, your car will sound a lot nicer as well.
