After riding this bike for a month, I think it was too quiet and with genuine muffler. I hear nothing but only wind over 60km/h (40mph).

So, I decided to replace the muffler and chose Delkevic’s slip-on carbon-fiber exhaust muffler. Because, it is really bargain price.

Those are the middle pipes.

And those are exhaust hangers. Something’s wrong.

Stickers.

And the mufflers. I chose 350mm KIT2674.

You can see the baffle in the back.

From the engine side. By the way, the baffle is removable.

It was easy to install, but something is wrong.

As I thought, the hanger were different. They sent me the correct ones immediately.

Ta-dah!

I uploaded a comparison of sounds, so please refer to it.
