Details:

It's not just the power and quietness!
The muffler sound will not bother people inside car, but once you put the gas it will have sporty sound.

This is the ideal muffler shape!
The φ 75 without the throttling and straight design gives big power and low exhaust pressure and still comfortable sound for the inside of the car.
