Upgrade from the stock X3M/ X4M S58 downpipes to the S58 catless downpipes for maximum airflow, power, and sound! Upgrade to the BMW 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. Expect up to a 30HP increase on a tuned BMW S58 with stock turbos, even more on cars with upgraded turbos.
