This center section deletes the front muffler on the 2019+ G29 Z4 M40i. This section reduces exhaust restriction while saving weight for better performance. The Akrapovic Z4 center section is a stainless straight pipe design with a Y-pipe merge collector. This center section fits only with the Akrapovic Z4 M40i rear muffler.
Akrapovic sound is distinctly European and exotic. Engineers tune every tube, muffler, and tail pipe to complement the powertrain. Many other vehicle parameters, such as vehicle speed, rpm, exhaust gas temperatures, and vibrations, are measured and correlated with the sound output to avoid unwanted vibrations or resonances. They further tune the exhaust to produce a thoroughly refined exhaust note that complements and accentuates the BMW engine.
In addition to sound tuning, engineers monitor exhaust gas flow and backpressure to improve performance and horsepower without affecting fitment or sound. Prototypes go through flow testing, dyno testing, and road testing to ensure there is no loss of power and that the optimal blend of sound and performance is achieved.
Akrapovic (ah kropoe-vich) is recognized as perhaps the most premium exhaust manufacturer for high performance cars and motorcycles in the world. Akrapovic's innovative use of materials like titanium and Inconel put them in a upper hierarchy among manufacturers and the racing and performance world has taken notice. All exhaust and carbon fiber products are designed and manufactured in Slovenia with very advanced methods including 3D CAD/CAM. Akrapovic exhausts have been used on MotoGP, Formula 1, Prototype, DTM, GT, and Touring race cars. They have been adopted by manufacturers such as BMW and Yamaha. Akrapovic is the exhaust technical partner for Aston Martin Racing, Audi Sport, and BMW Motorsport.
Note: This exhaust system is designed to change the tone and increase the volume of the exhaust. Some states or jurisdictions have strict sound regulations that prohibit any changes to the factory exhaust. It is the responsibility of the vehicle owner to ensure his/her vehicle complies with all federal, state, county, or local regulations. Installation of this exhaust will not increase emissions nor cause a check-engine light or fault codes on a properly maintained vehicle. It was developed to work with all factory emissions controls and equipment.
