Final answer:
The advantage of the 2020 370Z NISMO's H-pipe configured exhaust system design is improved engine performance through better exhaust gas flow.
Step-by-step explanation:
The advantage of the 2020 370Z NISMO's H-pipe configured exhaust system design is that it improves engine performance by increasing horsepower and torque. The H-pipe design allows for better exhaust gas flow by merging the exhaust gases from each bank of the engine, resulting in improved scavenging and reduced backpressure. This design feature can enhance the overall driving experience, providing a more responsive acceleration and a deeper, more aggressive exhaust note.
