Impression
It's great value for money! The changes in appearance and sound are obvious, and there are many areas where you can feel the difference, so it's a great value for money.
Cold idling (1500 rpm) is quite loud, about 9 dB louder than stock. Once it settles down (750 rpm), it's comparable to stock, with almost no noise entering the cabin.
On the other hand, while driving, the racing sound actively enters the car, motivating you.
Personal thoughts
Appearance: ★★★★★
Sound: ★★★★★
Price: ★★☆☆☆
If you want to make your car sporty, we recommend that you incorporate this into your customization first, as it is expensive and there are almost no other options available.
