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

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

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

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

Mostly Satisfied

Used with NojimaExhaust pipe + TricksterShotgun.
I chose the W Wall S Size because the sound was much louder and the after sound was great. As a result, the sound became 10% quieter or not?
I feel that the sound quality has been improved. But I feel that the sound quality has improved. The sound is now beautiful and low quality.
After has also improved a lot, albeit somewhat.
Has the low-speed Torque recovered?
I guess I was satisfied with my purchase when I looked at the Total.
As for the muffling, it may be no sound at all in M and L sizes. View detail

For volume control

I use it for BL-Factory's Exhaust System.
I have another M Size one and it measures close to the proximity exhaust sound measurement, according to Suma Four Pre's Volume Meter.

BL-Factory MBaffle 110dB
BL-Factory MBaffle + Automatic magic Inner baffle M Size 108dB
BL-Factory MBaffle + Automatic magic Inner baffle S Size 105dB
BL-Factory SBaffle 103dB
BL-Factory SBaffle + Automatic magic Inner baffle M Size 98dB
BL-Factory SBaffle + Automatic magic Inner baffle S Size 96dB

The result was that View detail

Volume drop is only slight.

When I bought a used BMW R1200S, it had a ZARD Silencer installed. At the time of inspection, the Motorcycle shop told me that the volume was a little too loud, so I changed it back to OEM. I had to change it back to OEM every time I had my car inspected, so I installed it for a trial run. It is not so much a change in volume, but just a little bit more "Large" sound. However, the after fire at ThrottleOff has been reduced, and the low speed and low RPM driving has become stickier, and the jerky feeling has been eliminated. I expect that fuel consumption will improve because I can run at one higher GEAR. View detail

Volume control

I have a TricksterShotgun silencer installed on my MORIWAKIFull Exhaust System, but the regulations are getting stricter and stricter, so I purchased an inner baffle.
It was not easy to ride after installation, but I was finally able to see the effect of riding.
As for the effect, the volume seems to have changed a little, and I read that the Torque is increased, so I checked that as well when starting off, and I think it is effective because it is easier to start off Smoothly.
If I wanted to turn the volume down a bit more, I would prefer S over M. View detail

I think there is almost no muffling effect …….

SCPROject's Full Exhaust System for MT-09 and XSR900, 3-Quantity:1pc. nick'70s installed on a EURO4 Spec. with Thailandco.
The mounting position will be right after the Thailandco Φ60 and the claws are up and snug, and I put in the S Wall Type, but measuring the Pipe, it looks like the W Wall Type will fit too.

I chose the SizeS because I thought the sound deadening effect would be large, but I did not feel that the volume became small from the characteristic of the exhaust system.
There seems to be Torque up, but I don't know the effect because I installed it without test driving after changing Exhaust System.

It's probably better than nothing because it's S Wall Type, but I put it in anyway, so I'm assuming it's effective and using it. View detail

It's well made, but...

I used it for Tsukiji TR. It is possible to install it like Mr. Tsukigi's Included Parts:even if the nail for the fixation is not raised especially by pontification. I think that the volume is slightly down. (Idling) Low speed Torque is slightly improved (Start is easy) TR tube is explosive sound in the first place, but I wanted it to become quiet a little more. （When I replace the ZX with a good exhaust system, the Idling becomes unstable, but after installing the Baffle, it has calmed down a little. The high speed does not feel the influence so much even if it does not do the fuel tune setting. By the way, when End Baffle is installed, it is quieter than OEM. I am not satisfied with the high price though the production is good including welding. View detail

Automatic magic Inner baffle

I installed this on a ZZr1100 Mather assembly tube. Basically, it can't muffle the sound. However, it will increase the exhaust resistance, so it will increase the torque. Of course, high rpm will be sacrificed. View detail

It is perfect for those who want to reduce the sound a little. (especially bass).

I like the sound and style of the exhaust system of YOSHIMURA. I bought it to reduce the sound a little more to go to RidingSchool.
It is just for reference because it is the volume of the smartphone app, but Idling was 88.6→86.4db in the diagonal rear, and it was 103.0→98.5db in the side of the car body when it was blown to 5000rpm. The bass is cut, but the high rpm is clear and the sound is not muffled.
After replacing the exhaust system, I had to be careful not to stall the engine when starting, but now I have more room. Also, the jerkiness of the 5th gear at 45mph has calmed down.
Then, I was worried that my GSR750 had an individual difference, but when the engine started to rev down, it would start braking with a bang bang bang bang bang bang bang bang bang bang bang bang. Now it's calmed down and the embracing itself has loosened up.
Also, there's less AfterFire ya.
The price is high, but I am satisfied with it because I will probably never replace it. View detail

VMAX 1200

In the case of 4500rpm, when I measured, with Automatic magicInner silencerwsSize, from 102-103db to 98-99db, 4 to 5db surely dropped. The price is high, but it is only high. The price is high but it is worth the high price. In addition, the silencer section has a 100mm long section with a wmSize Baffle that has been rolled with more Glass Wool, and at that stage, 108 to 109db dropped 5 to 6db from 102 to 103. If I put two Baffles, 10db will be lowered at the most Large. After that, I put on OUTEX Catalyzer100 Cell, the function of the muffling is about 1db lower, but the smell has decreased a lot, but only Owner can understand because Motorcycle is Motorcycle. The most effective is the Baffle on the end of the silencer, I have a DAYTONA End Baffle and it has reduced the sound from 115-116db to 110bd. If you want to muffle the sound without changing the sound quality, Automatic magic's Inner baffle is the best choice. However, I think that Glass Wool will be ruined soon. It's a great way to make sure you're getting the most out of your purchase. I'm glad I bought it. Please refer to it. View detail

Fine-tuning to fit the size

The size didn't fit and I had to fine tune it.
I chose the S Size and it is definitely muffled and quiet.
Inner baffle and End Baffle make it as hush as an OEM.
However, be careful because the top will not turn at all.
The price is high. View detail

The muffling effect is subtle, but...

It is used in combination with BEETSingle SilencerSlip-on Silencer.

Installation is easy and accurate as shown in the Instruction Manual.
You may think that there is not so much change in the sound deadening effect as you expect, but the lack of torque feeling at low rpm, which is common with the external exhaust system, has been improved and the instantaneous fuel efficiency at cruising has gone up.
There is no clogging feeling at high rpm and the performance of 14R is the same as before. /The performance of 14R is the same as that of 14R, which can easily go out to XX? (Lol)

I thought the price was a bit high, but it worked in terms of performance, so I'm happy with the results!

I'm sure the quality is there, but..

I bought the CBR250RR Full Exhaust System to counteract the dullness and muffle the sound of the feeling It is Installation is easy because you only have to insert it into the end of the middle pipe
I'm happy with the low speed dropout to some extent, but the price is still Neck
If you buy it for the purpose of muffling sound, I don't do Recommendation You can muffle the sound if you put Glass Wool around the middle pipe and Punch tube View detail

I bought it for its muffling effect, but the effect was not as good as I expected

Seeking the muffling effect of the SCproject Sc1 in STREET TRIPLERS Φ60W-I bought the S. I'm very happy with the sound quality, but the muffling effect was not as good as I expected The sound quality became better, but the muffling effect was not as expected At high RPM range, it was a little clogged If you want to get the sound deadening effect, the Long Type is better But the price is high and it's difficult to try different types View detail

Not enough for the purpose of turning down the volume

Striker's HYPERDimension (Full titanium) Attached to
As it is, the volume of the car is not inspected (over 100db) But even after installing this product, I don't think the volume has dropped much I'm still concerned about starting the Engine in a residential area
The sound quality, which was just“galloping”and felt coarse, has definitely improved and It has a Mild heavy bass It is pleasant to drive with no hindrance to extension at high rpm

If your goal is to lower the volume, we recommend the Long Type View detail

It's a sound I like

After replacing the Exhaust System, because the sound is too large, I changed the Exhaust System to fit the diameter of the car I put in the Inner baffle I can feel the effect right away after I put it on, and it makes a huge difference with or without it I am very satisfied with the results View detail
