【DAYTONA】Inner Silencer (Glass Wool Silencer Type) Review
Effective
Used for muffling of YOSHIMURAExhaust System for Initial Model GROM.
As a result of trying out variously, I was concerned about the durability of Glass Wool but this was the best sound deadening performance and sound quality.
Although it does not correspond to NORMAL, it is quiet enough and there is no performance deterioration in daily use.
Processing
Baffle Because the outer diameter is about 2 mm Small, it is 0. We wrapped 3 mm Aluminum plate 2 rounds.
I was worried about the scattering of Glass Wool so I rolled Aluminum mesh.
Since cheapness stands out when wearing it, I painted black on the place that can be seen from the outside.

Not much volume reduction. Might need to work on it.
I used Φ47 on a SR400 one-off muffler.
The image is after installation. You can see that the aperture is slightly narrowed at the back.
The construction is good and the Parts themselves are satisfactory.
It is Straight Type, not Interference Type, and the aperture is slightly narrowed.
Since the amount of Glass Wool is only a little apologetic, the muffling by the Glass Wool is hardly functional.
I wish there was at least twice as much because it is too little and blows right off the edge.
The main point of this product is that it has a larger diameter than a typical Chinese baffle, but this makes it less effective in muffling sound.
Even if the aforementioned Glass Wool is re-stuffed, the sound is Large-timed because of the caliber of the bore.
The exhaust energy of SR400Level is about 3db lower than that of SR400Level when this product is installed as it is (I wish I had measured it). Therefore, it is difficult to make an exhaust system that makes a lot of noise to be more powerful.
I think it would be quite effective for 125cc to 200cc with a little less Engine Displacement Volume.
If you want to use it for a larger Engine Displacement Volume, I think you can enhance the effect by putting two in series or creating an impulse in the middle like in the Illustration to eliminate the straitened state. The object itself is good, so it depends on the processing.

To muffle the sound of the external Exhaust System!
[How is it used?
When I installed an external Exhaust System on my cbr600rr, it was almost intuitive Sound.
Buy this one.
Was the one you received as per Image?
The size is perfect. 2 inch type, I think.
Was the installation difficult?
Since a hole is required for fixing the inner silencer, the machining of the hole was Large strange.
How was your experience with it?
It has a slight muffling effect, but it is still noisy, so I packed two Stainless Steel Scrubbing Brushes. It is much quieter.
[Included Parts:were they on?
[Was there anything that disappointed you?
