Want the best sounding exhaust system for BMW 340i or 440i?
The Evolution link pipe set upgrades the Akrapovic Slip-On exhaust system to the Evolution system.
The Evolution link pipe set is constructed of high-quality austenitic stainless steel.
It features an arrangement of two central link pipes, which replace the single pipe stock design for the best flow of the exhaust gases from the engine.
It is designed to increase power and torque and reduce overall weight, while delivering a deep and raspy sound with no unwanted drone.
When installing the Akrapovič Evolution link pipe set, remapping the ECU is mandatory in order to prevent potential check engine light warning signals.
