●Performance comparison


- The maximum values for both power and torque exceeded the stock system
- When measuring the power output, we also measured the exhaust pressure (*). As the engine speed increased, the difference became larger, confirming a significant reduction in exhaust pressure.
- With improved exhaust efficiency, making a muffler that will show its true value in further tuning!!
