Upgrade from the stock S63R downpipes to the MAD S63R catless downpipes for maximum airflow, power, and sound!

Upgrade to the MAD BMW S63R 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 S63R 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:

• Compatible with right-hand drive and left-hand drive vehicles
• Smooth bends for maximum airflow without any drone
• Up to 30HP increase on the stock turbos, even more on upgraded turbos

Fitment:

• 2019+ F95 X5M
