The G87 M2 is a performance-oriented vehicle that has garnered attention for its impressive engineering and design. One of the most discussed upgrades among enthusiasts is the Akrapovic exhaust system. But how much horsepower does this exhaust actually add in real-world testing? In this article, we will delve into the specifics of the Akrapovic exhaust and its impact on the G87 M2’s performance.
Understanding the G87 M2
The G87 M2, part of BMW’s M line, is known for its powerful engine and dynamic handling. With a turbocharged inline-six engine, this car is designed for speed and agility. However, like many performance vehicles, there is always room for improvement. Upgrades such as exhaust systems can enhance performance metrics, including horsepower and torque.
The Role of Exhaust Systems
An exhaust system plays a crucial role in a vehicle’s performance. It helps to expel exhaust gases from the engine, which can improve engine efficiency and power output. A high-performance exhaust system, like the Akrapovic, is engineered to reduce back pressure and enhance airflow, leading to potential gains in horsepower.
Akrapovic Exhaust Overview
Akrapovic is renowned for producing high-quality exhaust systems that not only improve performance but also enhance the sound of the vehicle. The Akrapovic exhaust for the G87 M2 is designed with precision engineering and high-grade materials, ensuring durability and performance. Key features include:
- Lightweight titanium construction
- Improved exhaust flow efficiency
- Enhanced sound profile
- Easy installation process
Real World Testing Methodology
To determine the actual horsepower gains from the Akrapovic exhaust, various tests were conducted. These tests involved:
- Baseline dyno runs with the stock exhaust
- Installation of the Akrapovic exhaust
- Follow-up dyno runs to measure horsepower and torque
- Real-world driving scenarios to assess performance
Baseline Performance Metrics
Before installing the Akrapovic exhaust, the G87 M2 was tested with the stock exhaust system. The baseline performance metrics recorded were:
- Horsepower: 453 hp
- Torque: 406 lb-ft
- 0-60 mph: 4.1 seconds
Performance After Installing the Akrapovic Exhaust
After the installation of the Akrapovic exhaust, the vehicle underwent further testing. The results showed a notable increase in performance:
- Horsepower: 475 hp
- Torque: 420 lb-ft
- 0-60 mph: 3.9 seconds
Analysis of Results
The testing results indicate that the Akrapovic exhaust adds approximately 22 horsepower and 14 lb-ft of torque to the G87 M2. This improvement is significant, particularly for enthusiasts looking to enhance their vehicle’s performance. Additionally, the reduction in weight due to the titanium construction contributes to the overall agility of the car.
Sound and Driving Experience
