Akrapovič BMW M3 (E9X) Evolution Exhaust System
The Evolution performance exhaust system for the BMW M3 is designed to deliver exceptional power and sound enhancements. It features dual-outlet mufflers, flow-optimized link pipes, and an X-pipe that incorporates high-flow 100 cpsi sports catalytic converters and resonators. The system provides remarkable power and torque gains across a broad rpm range, significantly improving responsiveness during all phases of driving. In addition to these performance benefits, the Evolution system offers substantial weight savings, dramatically improving the power-to-weight ratio of the vehicle. The system is engineered to produce a deep, rich growl at cruising speeds, while also unleashing an aggressive roar during spirited driving.
Please note that when installing Akrapovič aftermarket optional downpipes with sports catalytic converters or without catalytic converters—designed for use on closed tracks only—remapping the ECU is mandatory. Additionally, for any Akrapovič aftermarket exhaust system developed for closed track use, we recommend remapping the ECU to prevent potential “check engine light” warning signals.
IMPORTANT: THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
