New MAD Product Release - F90 M5 CATLESS + CATTED DOWNPIPES S63R

MAD BMW F90 M5 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*

Features:


Pretested on a vehicle for fitment
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
Lifetime warranty on defects and fitment
90 day return period
All orders ship in 1-2 business days
Flex section

Not necessarily there are 1000's of cars with midpipes and secondary cat deletes that have 0 issues with the dealer and warranty.

A dealership can deny a repair under warranty if the aftermarket part caused the damage.

These pipes actually reduce pressure on components so they shouldn't be blamed for causing any type of damage.

Worse case they can deny to work on the vehicle but thats very unlikely for a secondary cat removal.

Is it fair to assume that these inexpensive 200 cell high flow cat downpipes, like other inexpensive 200 cell catted primaries (CTS, ER, RD) are for smell control or to improve the environment, but that they won’t prevent a CEL? The high flow cat primaries that I am aware of this far that will not trigger a CEL are $2000-$4000.

You are 100% correct.
