Good at low rpm.

I used it on a VIRAGO250 Drag pipe.
At low engine speeds, the treble sound was muffled compared to the Exhaust Interference Silence Type, resulting in a mild sound. If I had to say so, I would say that the bass sound remained.
However, when the Axel was opened to high RPM, it became difficult to open, probably due to the Glass Wool, and the sound seemed to become a little louder.
In contrast, with the Exhaust Interference Silence Type, the Axel was easy to open even at high RPM and the sound was not as loud. However, at startup and at low RPM, the sound is a bit high pitched and light.
In the end, we decided on the Exhaust Interference Silence Type inner silencer, which is easy to run. View detail

I should have gone with DX.

I used to use 57.5φ ones from DAYTONA, but they were getting damaged and I used these to replace them.
DAYTONA's inner silencer was a Short Type, but KIJIMA's was a Long Type.
As expected, the middle area on the Exhaust System side was narrowed like a BottleNeck, and the bulge on the front side of the Silencer had to be cut off with a grinder, but it was within the expected range, so no problem.
However, the supplied Glass Wool sound deadener was only one roll of PelePera, so I added an old one and packed it in the box.
Minus point was the lack of Glass Wool in the new one alone.
Next time, I will consider modifying the BottleNeck part on the Exhaust System side to make it straighter so that I can use the Mad Max product.
For now, we have also achieved our original goal, so this is our evaluation. View detail

Muffled replacement available

There is a muffled replacement and you can hear the bass well. View detail

KERKERMegaphone on the Inner silencer.

The inner diameter of the pipe after the assembly part of the KERKERMegaphone installed on a Z650 is Φ60, so I bought it to use as an inner silencer for vehicle inspection. The proximity noise level when installed as it is is about 97-99dB using a noise measurement application. How reliable is the app? But I wanted to muffle the sound a little more, so I stuffed Glass Wool inside the punching pipe.
In this state, it is now 95-97 dB, so for now, the car will be inspected with this.
I had hoped for a more muffled sound, but the StraightPunching pipe did not produce the Large effect I had hoped for. View detail

It's just that the volume will be lowered, but..

Motorcycle：KLX125
Exhaust System：OVER Stainless Steel Carbon Exhaust System

History
KLX125 OEMExhaust System sounds too small to notice the automobile I couldn't get it, so I changed it to the Full Exhaust System of OVER, and I had a dangerous experience rarr;End It became an annoying sound explosion even with Baffle, so Inner Consider purchasing a silencer

?attachment
Because the end shape of the Silencer is not straight, it is called the exhaust pipe and Mounted between Silencer
(It's only held in place by the momentum of the exhaust rather than mounting, so if you give it a shock, it will move )

Good points
The sound of the external exhaust system's single-cylinder sound, like a group of half-greater cylinders, is not too loud Became sound enough to Appeal the presence in the automobile
It's cost effective in terms of ensuring that the volume is reduced

Bad points
After about a month of use, I found out that the rust was on the large..
Stainless steel is still the best inner silencer

There is a certain amount of sound deadening effect

This is for the external exhaust system on my Harley
Glass Wool of thinness is rolled from the beginning, but when I use it, I will use it as well as one roll of Glass I added the Wool and then inserted it
Without Inner silencer, the regulation volume is lightly exceeded, but it is 94db when installed The volume dropped to View detail

Normal

Bought it to reduce the sound for my custom made Yamaha sr400 exhaust,it will silent the sound at lower rpm range of my exhaust but Doesn't work at higher rpm range the sound note would become even fatiguing,I guess this is subjective for different exhaust. View detail

With silencing effect

Added to XL 1200 C SPORTSTER 1200 External Exhaust System.
Buy this item whose inner diameter is the closest.
The cotton part is hard and hard, it will silently sound.
Because the exhaust pressure of Motorcycle is high, cotton became a mosaumosa in a relatively short time.

Although it is not currently used, I think that it is effective when lowering the volume of Exhaust System at the time of vehicle inspection View detail

It has an effect

I used it for the XL 1200 C SPORTSTER 1200 Exhaust System.
Exhaust System was a sharp exhaust sound near the straight pipe outside the company,
After installation, the sharpness of the sound calmed down, and it became a slightly muffled sound.
It is an impression that the sound is rounded.
I think that the volume was also suppressed and it was effective enough View detail

Muffler effect perfectly

Since the Other Company Product Expression System of CRF 230 F was a bit of explosion to run on the public road, we installed the Inner silencer.
Because it is a Universal Product, we need some ingenuity, but the effect is outstanding.
It's not too quiet, it's too noisy.
I can recommend it.. View detail

Large satisfied

I attached it to Slash Cut Exhaust System of VIRAGO 250.
Easy to install, it became a very nice sound.
As my feeling, it sounds like I made the sound of a straight pipe purely Small.
The power of the sound has increased with a little expense and I am very happy. View detail

It is an ordinary inner silencer. Since it is consumable goods, cheap one is good. Of course, silence is also O. Be careful of a size in the case of purchase.

Although it had equipped with the custom muffler almost near a straight pipe, the nuisance to the neighbors was considered and purchased.
As operative, although it does not become precocious, it becomes abbreviation half [ of the state of a straight pipe ], and a high sound with sufficient normal in which tone quality also bursts disappears, and sound volume becomes crisp touch, and is large satisfaction.
It is the good touch which adjusts the grade sound volume which is the quantity of glass wool.
Muffler sound can be enjoyed now, without seldom caring about a nuisance to the neighbors.
However, about attachment, it was fairly troublesome.
Since this product is made more greatly about 1 mm than a notation size for exhaust leakage prevention, it does not enter, unless it will delete the outer circumference of a fixed portion, if an apt size is purchased.
Although I used the grinder, I think that it becomes fairly serious work in case of manual operation.
And since just it has worries about exhaust leakage when becoming distorted, the way which purchased the size smaller than a size needed from the beginning, and filled the crevice with the gasket may be comfort. View detail
