[How is it used?
I purchased this for Step up from NORMAL.
Was the one you received as per Image?
The Exhaust System was smaller than expected.
Was the installation difficult?
The Exhaust System itself is small and light, so it can be installed easily.
How was your experience with it?
The volume is moderate, and it looks and feels customized, but no performance increase is expected.
[Included Parts:were they on?
Bracket required for installation was included.
[Was there anything that disappointed you?
The volume went up, but I did not feel any performance increase.
Nothing else in particular.
Power may increase from NORMAL, but those who have already changed to an external exhaust system, etc. may not experience power increase.

*The image above is for DUNK..
The design is simple, calm and high quality.
In terms of performance, exhaust pressure control ensures smooth running from low to high speeds.
High quality glass wool and steel wool are used for the sound deadening material, so the sound is quiet and produces a heavy bass sound.You can enjoy the pleasant bass sound.
Baffle (sound deadening part) is equipped as standard, so you can select two different volume levels with a simple operation.
Use the silencer band to secure the silencer at two points.Easy bolt-on installation.
The center stand can be installed and used without modification.
There are 4 types of silencer outlet: Bazooka type, Popper type, Sport type and Euro type.
The difference is only in the design, not in the performance, so you can choose the one that suits your taste.
Points of Attention

It says it's been shipped, but there's no Yamato tracking number on it, so I don't know when it'll arrive!
