MAD BMW S55 CATTED DOWNPIPES M2C M3 M4 W/ FLEX SECTION

Upgrade from the stock S55 downpipes to the MAD S55 catted downpipes for maximum airflow, power, and sound!

Upgrade to the MAD BMW S55 downpipes to eliminate the back pressure 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 S55 with stock turbos, even more on cars with upgraded turbos.

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.
