Talking Mastery of Art & Design B58 Downpipe ***NEW PRODUCT***



Mastery of Art & Design (MAD) specializes in BMW bolt-on aftermarket parts. The current catalog includes BMW charge pipes, downpipes, and intercoolers. All high-quality pieces backed by a fitment guarantee and a lifetime warranty!

MAD offers 90-days to return any product; if you do not like it, send it back.

Upgrade to the MAD BMW 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 BMWs with stock turbos, even more on cars with upgraded turbos.

Features:
  • Smooth bends for maximum airflow without any drone
  • Up to 30HP increase on the stock turbos, even more on upgraded turbos
  • Lifetime warranty on defects and fitment
  • 90 day return period
  • Spot on fitment

Hi,
It does not fit the M550 . It only fits the B58 engine
