Akrapovic Catless Downpipe (Stainless Steel) for BMW M4 F82/F83 2014-2017 - Decat Track-Only - Evolution Line Compatible

Akrapovic race down pipe for BMW M4 S55 – F82 Coupe and F83 Convertible – 2014 to 2017

Take your M4 to the next level with Akrapovic’s non-catted turbo down pipe. Designed for circuit use, this straight-through front pipe frees up flow from the S55 twin‑turbo engine, sharpens response and delivers an aggressive motorsport tone without the droning that spoils road trips. Built in high quality stainless steel with Akrapovic’s hallmark precision, it is the ideal foundation for tuning and pairs perfectly with the Akrapovic Evolution exhaust system.

We run these on our own cars and customer builds and the feedback is consistently outstanding. If you are chasing maximum performance potential and a truly race-bred soundtrack, this is the upgrade experienced BMW enthusiasts choose.
