OEM Product quality outside the company.
Single-cylinder and two-cylinder motorcycles, such as the SR, are said to be motorcycles that enjoy style and sound. Therefore, there are many kinds of external exhaust systems to choose from. However, this time, we chose this one because we wanted to replace the OEM Exhaust System after understanding the OEM Exhaust System well.
To begin with, what kind of merit or demerit is involved in changing to an external exhaust system?
Merit
1:The appearance that matches one's ideal. dress-up effect.
2:Exhaust sound to your liking. Straight pipe construction without much sound deadening material like OEMs, so it is easy to produce sound. It can be a crisp exhaust sound or a roaring high-pitched sound.
3:Good disconnection makes it easier to feel Stress at high RPMs and easier to turn to higher RPMs.
High rpm is stabilized and most large horsepower is increased.
4:Lighter weight:2 kg or more lighter than OEM. The OEM exhaust system is heavier than the external system because of the complex construction of the exhaust pipe, which is wrapped with a muffler to suppress the loud noise. 。
5:The material is highly resistant to aging.
OEM exhaust systems are often made of steel, and if used for long periods of time, rust can cause holes and leakage of exhaust gas. 。 For external exhaust system, Plating Processed Steel, Material:Stainless Steel and Material:It is strong in Rust due to the use of expensive Materials such as Titanium.
Demerit
1:The vehicle may not pass inspection due to exhaust system noise. Also, there is a possibility that the exhaust gas standard may be exceeded by a large amount due to the large amount of exhaust.
2:Vibration may cause Stress to Passenger. OEMExhaust System reduces not only the sound but also the vibration associated with the sound by its internal structure.
3:Decrease in fuel consumption. The structure of the exhaust system is simple and easy to exhaust, which makes it easy to speed up, but it makes it difficult to start and accelerate. Therefore, the Axel is turned more, and more fuel is used than usual, resulting in lower fuel economy.
4:Low-speed Torque tends to drop in exchange for higher RPM.
So, the answer is "OEM is the best". It is not better to be satisfied with OEM, but people always want to improve the sound, looks, and performance.
So I thought,
(1) Exhaust Gas and volume of Japanese Vehicle Inspection Correspondence.
(2) Weight.
(iii) Manufacturer.
(4) Power characteristics close to NORMAL.
The task was to find an Exhaust System that met those desires.
And here is the Exhaust System.
good point
◎Japanese Vehicle Inspection Correspondence.
◎OEM 7.2kg, Planus 5.1kg→ lightweight.
◎Sakura Industries originally manufactures OEM exhaust systems for SR400 and YAMAHA vehicles. The quality, volume, and performance are unmistakable.
◎Tested by Chassis dynamo. Power output is good even without intake setting.
As for Demerit, it means that the price is high.
OEM exhaust systems are more expensive than external exhaust systems. Considering that, I don't think it is that expensive.
There is no right answer to the question of what to look for in an external exhaust system, and it varies from person to person.
If you understand how good the OEM exhaust system is, and if there is an external exhaust system that does not destroy the characteristics of the OEM exhaust system to a large extent, you may call it a good exhaust system. I think it is a good exhaust system. It is a pet theory (laugh).
We have introduced this method of selection because it is also possible.

Although high.
Very good product, albeit expensive …
OEMs are too quiet to have a presence, and vice versa.
Felt it was dangerous and converted it. The sound edge was well
I like it without being too loud.
I am old type, but New Model around me
As for Emblem, there are pros and cons.
Depending on the Custom condition, it may float.

Hmmm.
The construction is good, I just think the price is too high.
The sound is not too loud and not too quiet, but it is a little noisy when you open the Large Axel.
I use it for RH16J, but the valley which I do not feel in NORMAL is bothering me in PLANUS.
Specifically, I feel a valley around 4500rpm, when the Winding Corner starts up, when accelerating to pass, etc.
Sometimes the acceleration stops around 4500rpm and you have to Downshift to get it past 4500rpm.
It will not bother you on flat ground or in town etc., but I think it will bother you if you are running sporty.
This is a characteristic that makes me wonder if Sakura Industry does Bench tests but not much actual running evaluation.
In the end, I changed it back to NORMAL because this valley is a STRESS to run on.

The quality is worth the price!
The price is high for the size of the SR, but the quality is the same as the YAMAHA quality because it is made by Sakura Industries, a subsidiary of YAMAHA.
Naturally, the vehicle inspection is compliant with the 2018 and newer vehicles.
Weight:5.1kg for Planus compared to 7.2kg for NORMAL. It's not light, but it has super strict exhaust gas regulations. [Color] I think the developers had a hard time because they were doing it with Clear.
Durability:NORMAL same, etc... is packed tightly and will not deteriorate over time.
Sound quality:The pulse seems to be more loud at low to medium speed, but when you open the Axel at high speed, it sounds like it's going boom! And it's good to pop.
The texture:The plating layer is thicker than the NORMAL and the texture is quite good, and the Style is also a Large person because the tail is not jumped up excessively.
Performance:Because I put it on at the same time as Mr. SP Tadao's PowerBOXExhaust pipe, I don't know the performance with SilencerSingle Item, but the performance of the high rpm range was improved as total (TOPSpeed is up more than 20Km/h).

Fits: YAMAHA BOLT-R, YAMAHA BOLT-R, YAMAHA BOLT-R, YAMAHA BOLT-R
Improved appearance, sound quality and weight reduction!
I bought it because I thought it looked like the best of the ones that are adapted to the vehicle inspection
To install it, you have to remove the body and exhaust bracket because the holes don't fit as they are I tightened the Exhaust System and Bracket temporarily and installed them, then it was easy to do
The Flat black paint job is good, but it looks like it's going to get scratched quickly
The sound quality is more elegant and the volume is a little smaller than NORMAL measure (The bass sounded Smaller.)
Small TypeLight weight makes it look better and better

It's good, but it's still expensive
Finally, a planus that is compatible with the current model I bought it even though I thought it was expensive
Accuracy and texture are perfect Sound quality is not so different from OEM The sound quality is the same as OEM I wouldn't recommend it to anyone who values sound So that's a tough one
The Planus Emblem on the side is shining and makes me feel a little bit superior every time I see it!
But I think things are good, but they're still expensive I wanted it to be released in the 50,000 yen range at least
