The MAD 3.5" S58 Fat boy is the largest BMW S58 catless downpipe on the market!

Upgrade from the stock S58 downpipes to the MAD 3.5" Fat Boy  S58 catless downpipes for maximum airflow, power, and sound!

Upgrade to the MAD BMW 3.5" Fat Boy  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.

The flex pipe Section will help reduce the stress and unwanted vibration from the downpipes.

Features:

  • Largest 3.5'' Diameter piping compared to standard 3''
  • Compatible with right-hand drive and left-hand drive vehicles
