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.
Expect up to a 30HP increase on a tuned BMW B48 with stock turbo, even more on cars with upgraded turbo.
The heat will expand/weaken the pipes, while with engine movement, the flex pipe will help reduce the stress on that red hot expanded/weakened pipes.
