AMS Perfomance Uk M3 / M4 Downpipes 


The downpipes are made of T-304 stainless steel unlike all other cheap ones out there.


Will fit the following models:


BMW M3 F80

BMW M4 F82


Some advantages of our Decat pipe:


Better throttle response.

Relief of the turbocharger due to lower temperature and less exhaust back pressure. 

The cylinder charge is increased, which improves performance.


Car feels a lot more free and responsive with this installed and has increased power by 15-20 BHP on test vehicles.
