The G drum has three expansion designs, which increase horsepower while reducing torque loss with a larger expansion rate (the increase in horsepower is worse than that of the S drum, but the torque loss is almost zero). Generally speaking, the number of tailpipes depends on the displacement of the car. The larger the displacement, the more exhaust gas is emitted, so the larger the displacement, the thicker the tail throat, but this is not true!

Exhaust sound: The front and middle sections of the G drum have excellent performance, with slightly better low torque than the S drum and lower sound waves.
