BMW M3 M4 F80 F82 F83 REMUS EXHAUST (2014 - 2020)

by Remus

Remus BMW F80 M3 F82 M4 Axle Back Exhaust System improves airflow of exhaust gases for greater performance and a less muffled exhaust note.

Why choose the BMW F80 M3 F82 M4 Remus Axle Back Exhaust System?

The Remus Axle Back Exhaust System has a diameter of 70mm, 5mm larger than the OEM exhaust system. This increased diameter allows the exhaust gases to escape more quickly, reducing back pressure. This provides a slight power and torque increase, whilst unlocking far greater tuning potential. The Remus Axle Back Exhaust System also comes in lighter than the factory system which has other vehicle benefits including acceleration, braking and handling.

The Remus Axle Back Exhaust System for the BMW F80 M3 & F82 M4 integrates with the factory valve system, retaining the functionality of the vehicles active exhaust electronics.

This system has EC homologation, meaning it's completely legal for road use.
