At the time of vehicle inspection, it was pointed out that the proximity exhaust noise was at the very limit due to deterioration of the muffler over time, so I was looking for a quiet muffler.
AutoExe's muffler was recommended by the dealer, so I chose a dual tail type stainless steel muffler since the normal muffler.

After installing it, I ran about 100km and realized that the exhaust sound was quiet as intended.
However, there is no change in the feeling of power, and I think that you can enjoy driving as before.
