Upgrade to the MAD BMW S63R downpipes to eliminate the backpressure caused by your stock catalytic converters. Upgrading to our downpipes allows your turbos to 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, and even more on cars with upgraded turbos.

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