Key Features of the Akrapovič Exhaust System
- High-grade titanium construction for weight reduction.
- Optimized exhaust flow for enhanced performance.
- Distinctive sound that enhances the driving experience.
- Easy installation with a perfect fit for the BMW Z4.
Dyno Testing: Measuring Performance Gains
Dyno testing is a method used to measure the power output of a vehicle’s engine. By connecting the car to a dynamometer, technicians can accurately assess horsepower and torque before and after modifications. This process is essential for quantifying the performance benefits of the Akrapovič exhaust system.
Before and After Comparison
In a controlled environment, a stock BMW Z4 was tested on a dynamometer to establish baseline performance figures. The following results were observed:
- Stock horsepower: 250 hp
- Stock torque: 300 Nm
After the installation of the Akrapovič exhaust system, the same vehicle was retested. The results showed a remarkable increase in power:
- Modified horsepower: 275 hp
- Modified torque: 320 Nm
Benefits of Upgrading to Akrapovič
The addition of the Akrapovič exhaust system not only increases horsepower but also offers several other benefits that enhance the overall driving experience.
- Improved Throttle Response: The optimized exhaust flow allows for quicker throttle response, making the car feel more agile.
