MAD BMW F9X M8 DOWNPIPES S63R

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.

Choose between these options

Primary and secondary - Most power and Sound *Tune required for Cel*

Primary only - Power & sound without the smell *Tune required for Cel*

Secondary only - Slight Increase in Power and sound without the need for a tune *no cel*

Around 5 + hours seems to be normal.

May I ask why installing the same downpipes on an M5 takes only 3~4 hours? What’s so special about M8? I got quoted for 6 hours of labour which seem to be way too long

Yeah, that seems to be more like a normal time as the youtube installation video also took around 3 hours

No difference but most shops charge around 5 hours of labor.

[g2lujinn]

Alright, found another shop who’s willing to charge 4 hours of labor, this makes more sense
