● Mounting parts: Air filter replacement, intake suction kit, sports muffler (center dual)

I installed the filter and intake suction kit, thinking that it wouldn't change much, but the response of the engine became lighter enough to be clearly seen.I am more satisfied than I expected.

One month later, I put on a sports muffler.
Exe said that the torque will increase at the exhibition, but it is a drastic change in the middle rotation range of 2000 to 4000.
The torque has been increased in the practical range, making it very easy to ride.
There was almost no change in the fuel efficiency that I was worried about.
Regarding the sound quality, it is a very good tone both inside and outside the car, but at around 2500 rpm, the bass is muffled inside.
Depending on your physical condition, you may feel uncomfortable. (I don't care if it's open)
The rear view is the best when installed at the same time as the rear under panel.
