Akrapovic Evolution Titanium Cat-Back Exhaust System for BMW G90 & G99 M5

Description

The Akrapovič Slip-On Line Titanium Exhaust System for the BMW M5 G90 (sedan) and G99 (touring) is a premium performance exhaust upgrade that dramatically enhances exhaust tone, reduces weight, and improves flow over the factory system. Precision-crafted from high-grade titanium with carbon-fiber/titanium tailpipes, this exhaust delivers a deep, athletic sound and measurable performance gains while retaining the factory valve-control functionality for refined acoustics in all driving modes. Akrapovič’s engineering ensures smooth integration with BMW’s electronics without requiring ECU remapping.
