【Auto Magic】Inner Baffle Review

Effective for Torque up (Sound deadening effect?)

AKRAPOVIC's Full Exhaust System&Silencer on MC51 (for Race) The combination of the two was used.

In the Circuit, the inner baffle was too loose without the baffle and the Torque was insufficient at low RPM. (BF50S/M) attached.
Torque recovered, but the exhaust sound was still too loud and bothersome, so I purchased a one size small BF50S/S this time.

The sound deadening effect of the BF50S/M is virtually non-existent.
In addition, all of the sound deadening material burned out after about 20 minutes of Circuit driving.

I would like to check the effect of BF50SS in the next Circuit run.

The results were measured with a sound level meter before and after the replacement of M&arr;S.
(1m away from Silencer)
*Please use it only as a reference, as it varies depending on the measurement conditions.
BF50SM (Sound deadening material burned out)
12000rpm (114.6dB)
4500rpm (Not measured)

BF50SM (Sound deadening material rewound)
12000rpm (113.5dB)
4500rpm (96.4dB)

BF50SS (with sound deadening material (new)) )
12000rpm (110.9dB)
4500rpm (95.3dB)
Idling (82.1dB)

For those who drive on the street, we recommend installing JMCAMODEL's Silencer. View detail

Subtle Product.

It has been on the market for a long time now, maybe 20 years.
Used on a BuellX1 with a full titanium muffler from Kasuno.
The construction is quirky. The price is very bullish.
As for the effectiveness, there are other inexpensive and effective ways to muffle the sound. If you are looking for a back pressure control, you may be able to find some use for it, but if you are looking for a S size control, you may not be able to find a good solution.
Please buy one and try it.
I sold immediately. View detail

Somewhat effective

It seems that everyone is buying Bubble, Inner silencer, etc. because they think they are so effective!

The Silencer's original End Baffle is effective (because it blocks the exit).

The insulation, which is called "sound deadening material" in the middle of the road, does not muffle the sound (it does muffle it a little, but only a little).

This product is not very effective, but it does have some effect.
[That's about right. Buy on the second place!

I installed Type S this time, but M Type and Type L are almost meaningless (a little bit is possible).
The average person can't tell the difference between 90 decibels and 91 decibels.
90, 94 and 98 would be totally different.

It only muffles the sound to that extent, so don't give it an over-large rating.

What I'm trying to say is. [Not very effective]. that is to say
[Sound quality changes, volume remains the same. And [The volume changes, but the sound quality remains the same. And Brushbo!

If you want the effect, Long Type is the way to go (though I've never installed it). View detail

I guess it's better than nothing.

I write honestly and without discovery.
First of all, I don't like Automatic magic, but this product has been on my mind for several years (would I like it?).
It was in stock at WeBig, so I kind of bought it.

What did you think after installation?
Better than nothing? Degree.
I think the backward Long Type would be better.
I have Maverick's Inner baffle muffling type, so I am very interested in the backward type.
But I think it's great that the volume goes down with Items like this.

I'm attaching a photo and will leave a comment on the photo.

The exhaust system is StainlessYZF1000 THUNDER ACE of Over, and the silencer is GP Type of the early model of kFACTORY, but I am thinking of replacing it with Stainless carbon of techserfu that I have. I'm thinking of replacing it with techserfu's Stainless carbon.
I think this product would be the most efficient since techserfu is about the loudness of a Large person!
What I'm trying to say is that I want as webigPoint as possible with longer comments.

In case you're wondering, an average slight bending of the nails in three places was enough.
If the amount of bend is taken too Large, it will be difficult to return Large change.
The manual is very poor, but the person in MotorcycleManufacturer is a guy, so it is difficult to understand the manual if you don't have some knowledge of the product.
If you are not a self-starter, please ask a Motorcycle shop and pay for the labor (they should be able to take responsibility if something goes wrong).
This is a report from the field. View detail

The effect is subtle ….

The quality of the product is good, the welding is beautiful and the large size is good. The installation work was not difficult if you have the skill to install the exhaust system, and the size of the product and the inside diameter of the exhaust system is exact, so I did not have to adjust anything.
Exhaust System is Asahina RACING79S for GSX1100S KATANA. As for the volume, I did not feel that the volume was suppressed especially in the Idling condition.
However, I felt that the mid RPM range became Mild, although I opened the Axel and blip pinged it while the car was stopped.
The purpose of this purchase was to install this product as a countermeasure for the volume limit at the time of the last vehicle inspection.
We are very happy with our purchase. View detail
