Description
Shopping around for the best exhaust system for BMW Z4 M40i?
Manufactured to exacting specifications from high-grade titanium, with parts cast in Akrapovic’s in-house titanium foundry.
This system utilizes lightweight materials to reduce overall vehicle weight and optimize power and torque through the entire rev range.
Meeting ECE type approval, the design of the system fully adapts to the lines of the car, and the single-muffler layout with four hand-crafted, larger diameter, carbon fiber exhaust tips give a more aggressive look to the rear of your Z4.
Various sound modes add to the experience, with a raspy and animated roar from the six-cylinder engine when the revs rise, and a more pleasing experience in comfort mode, ideal for cruising with the roof down.
