Upgrade from the stock B58 downpipe to the MAD B58 catless downpipe for maximum airflow, power, and sound!

Upgrade to the MAD BMW / Toyota Supra B58 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 / Toyota Supra B58 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.

  • Compatible with right-hand drive and left-hand drive vehicles
