4/5

Lighter weight and improved throttle response

This is an impression with K&N's Filter and SP Tadao's PowerBox installed.
The assembly was requested to the Shop at the same time as the OVERSwing Arm for the one-year inspection.

[Weight]
It weighs about 2 kg less than the OEM Exhaust System.

[Sound Quality]
The thump-thump feeling during idling increases, and the sound becomes more Race ish before the power band.

[Volume]
It will increase. If you do not like this, it is better not to replace it.
This is the Level where you have to be careful in residential areas and you will want earplugs (Type with holes) for long-distance, high-speed touring.
Please keep in mind that the official introductory video does not turn to Power band, so please keep this in mind if you include it in your selection candidates.

Outputs
The throttle response is better, probably due to the lower exhaust pressure, and the feeling of shortness of breath in the latter half of the power band that was felt with the OEM exhaust system is considerably reduced. Before the replacement, the engine was screaming from 8,000 rpm, but after the replacement, I do not feel any strain even if I turn the engine up to 10,000 rpm (must be due to the filter). (There must be some influence of Filter)
In addition, the speed is higher than expected even when driving the same way as before the replacement, which suggests that the output Torque is improved from mid-range RPM onward.

I have heard that low speed Torque drops when changing to Other Brand Product, but immediately after the change, I felt that Power increased even at low speeds. After multiple runs, the Torque dropped slightly near the Idling area, so I assume that the fuel condition changed as a result of learning.
(AfterFirea sometimes appeared at medium RPM→low RPM with AxelOff, so the fuel mixture was not optimal)
I will try to take a power curve with Timing of Sub computer introduction. View detail

Cospa best

I liked the look and the fact that it is a Japanese Vehicle Inspection Correspondence was a deciding factor for me to buy it for a trial.
This was my first time replacing the Exhaust System, but it was easy because it is a Slip-on Silencer.
Even an amateur can replace it in about 30 minutes to an hour while reading the enclosed Instruction Manual.

【It was good point】
Bolt On allows for easy replacement as it is set up for each vehicle model.
When idling, the bass sound at low rpm is pleasant to listen to and gives the feeling that the exhaust system has been replaced.
They look good (depending on the individual) and are inexpensive.

[Things that bothered me]
The enclosed Instruction Manual shows a picture of WhiteBlack, so you have to look closely to see some of the details.
To be honest, the high-pitched sound at high RPM range may not be much different from before the replacement. To the untrained eye, I don't feel that the power has increased either.
The Gasket is included in the package, but it is not a tight enough seal and leaked air, so it is better to prepare Liquid Gasket separately (I didn't have it, so I went to buy it…)

I also found a bracket to connect the Silencer band to the car body, but I didn't like the angle and the chattering sound it made when idling if I put the bracket on. I think it's unnecessary …?
If you usually work on your own and have tools such as Hexagon and Wrench, you can easily replace them.
It looked and sounded different and was quite enjoyable.
The price was low, so if you take that into account, I think it is cosmetically sufficient. View detail

Slip-on Exhaust S1R Silencer

5/5

Silencer of YZF-R6 is changed to Carbon!

[How is it used?
AKRAPOVICSlip-on SilencerMegaphone until now (Titanium) I had been using a Silencer, but after driving over 30,000km, I decided to change and makeover the Silencer for a change of pace.

Was the one you received as per Image?
Size seems to be similar to OEMSilencer.
The AKRAPOVIC product I had been using up to now was just a gold-attributed Pipe, so compared to that, the AKRAPOVIC product is large and different, and has a presence after installation.
I feel that the black carbon matches the black body of the car.
The inside of the Kan is straight and hollow, and the airy appearance of the exhaust is exciting.

Was the installation difficult?
Since it is a Slip-on Silencer, installation is easy.
If the OEM can be removed, it may be possible to install.

How was your experience with it?
Anyway, the sound is pleasant.
The sound quality has changed to bass, probably because of the change to CarbonMaterial.
I thought that the volume would be quieter because the silencer part would be larger, but the sound is uplifting, and I feel a fresh feeling that I cannot believe it is a motorcycle that has been with me for over 15 years!
I had thought that only a Full Exhaust System could give me a pleasant exhaust sound, but the system has betrayed me in a good way.
YZF-R6OEMExhaust pipe catalyst (a.k.a. Bento Box) I had felt the limitations of the Slip-on Silencer because of the presence of the, what is it? What is it, say, a horn on a musical instrument? Does it have the same effect as a wind instrument? The bass is accentuated and exaggerated, and it sounds great.
And it goes around pleasantly from bottom to top.
Fuel consumption naturally worsened, perhaps because of the reaction to the change in driving style, which turned pleasantly up to the top. (LOL) 。
The sound quality makes you want to rev the engine to high rpm.
However, it also has a Torque feel from below, and its performance is clearly different from that of the previous Gold genus Pipe.
Stop&go in the city is also easier to drive than before.
A renewed sense of driving pleasure. It's wild!" Sound was obtained.
It is the best place to run.

[Included Parts:were they on?
A pipe is included to connect the silencer body to the exhaust pipe.
It can be connected tightly with high accuracy.
In addition, it is fixed with Spring, but it has a Spring cover, which seems to prevent chattering noise.
Mounting bracket, mounting bolts, and nut are included and can be installed right out of the box.
Two Brothers RacingSticker included.
I'm a little happy.
Maybe I'll put it on my toolbox.

[ITEMS TO BUY TOGETHER
Mounting bolt and nut were included, but they were made of a tasteless Stainless SteelSilverMaterial, so the bolt was replaced with a separately prepared one.
[Silencer band side] M8×15Bolt + M8Nut
[Body and attached Bracket mounting side]. M8×35Bolt + M8Nut
In addition, M8Spacer of FUJI Tsubo Type by KN Planning (Black) separately prepared and installed.
I installed it with a Bolt I had at home and the color is different, so I would like to replace it with a Titaniumium Bolt again sometime soon! View detail
