Shopping online? Don't worry! Our online store will remain active! We hope to ship orders placed for in-stock items as normal during the shutdown. Anything else will be dealt with upon our return.
Thank you for your understanding, String Theory Garage Team
BMW Z4 M40i (G29) | Akrapovic | Slip-On Line Exhaust System (Titanium)
Manufactured to exacting specifications from high-gradetitanium– with parts cast in Akrapovič’s in-house foundry – this system utiliseslightweightmaterials to reduce overall vehicle weight andoptimize powerand torque through the entire rev range. MeetingECEtype approval, the design of the system fully adapts to the lines of the car, and the single-muffler layout with four superb hand-craftedcarbon-fibreround tailpipes give a distinctive look to the rear of the car. Various sound modes add to the experience, with a sporty 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.
An optional Akrapovič Sound Kit is available to control the various sound settings, and optional tuning opportunities exist through the addition of the stainless-steel Evolution Link Pipe set. As with the Sound Kit, fitting the Link Pipe will negate the ECE type approval.
Fitment and EC type-approval are valid for engine type B58B30C. ECE type approval is only valid for cars equipped with otto/gasoline particulate filter.
For installing the slip-on system, the stock exhaust system has to be cut. Please read the instructions carefully before the start of the installation.
