Sports Exhaust

The Instruction Manual also says that some leakage and rusting should occur, but even so, the symptoms are severe.
I did some research and found a few cases of people suffering from similar symptoms.
Leakage does not seem to improve much after trying to reapply more liquid Gasket.
It seems that the shape of the Band or Gasket itself is causing the problem.
It would be better to re-fix it with a Stainless Steel hose clamp after applying liquid Gasket.
I'll have to cover up the rust with a heat resistant matte black...
Both are only symptomatic treatments and may not be fundamental solutions…

I was dissatisfied with the quiet sound of the OEM Exhaust System, but after installing this Sports Exhaust, I am satisfied with the crisp, single-cylinder sound.
Also, the engine response became to respond linearly to accelerator operation and I am satisfied.
If you don't want to break the NORMAL look, but want to make it sound better, this is a Recommendation product.

I bought it because I didn't want to ruin the OEM look too much and the price was reasonable compared to other products.

In conclusion, I'm pretty happy with it.
Compared to the clogged OEM exhaust system, the new exhaust system has a better release and spins up to higher RPMs, but it doesn't lose the large torque feeling underneath and feels like good balance.

I like the sound quality like an off-road motorcycle, but the volume is a large fine-tuned, so I think it is better to pay attention to those who have an influence on neighbors.

The silencer part is made of steel, so it can't be helped, but if you don't take care of it when you wash your car or after being exposed to rain, it will rust easily. (When I was touring along the seaside, I found rust on the welded part of the bracket where the paint would be thin.
I also had a leak from the connection between the exhaust pipe and the silencer, but this was solved by applying liquid gasket and tightening it a little tighter than the specified torque.

There is also a negative part, but it is an exhaust system that can be very satisfactory when driving becomes much more fun and it thinks in the cost effectiveness.

When I turn on the Cell and start the Engine, the first thing that strikes me is how good it sounds.
It's a good Exhaust System that makes Motorcycle feel like it's got some energy.
Compared to NORMAL, it has a higher response and a more nimble feel.
But my favorite part is the sound.
I would like to RECOMMEND you all to do the same.

Installation
To put it simply, you just need to remove the Under Guard, remove the Side cover, remove the OEM Exhaust System, and then assemble it in the reverse order of removal, so the difficulty is not so high.
However, it is necessary to remove the side cover in order to remove the fixing of the silencer, but this tends to be a hard time because the fixing method cannot be read from the outside and the position of the nail is bad (the nail breaks as shown in the image).
In addition, because the Side cover is fixed with the protrusion part and the bolt, even if the nail is broken, it is not a problem, or rather it is good because it became easy in the next work (removal of Silencer is necessary when changing Suspension).

[About performance]
The torque at low rpm is reduced a little bit, but at high rpm, the exhaust system has more power. Well, it is the shape and bore of the exhaust pipe that determines the performance of the exhaust system, but due to the characteristics of this vehicle, it has to be the same shape as the OEM exhaust system.
If that happens, you can use the Silencer to Pull it out. Or "Pack it in. If the OEM is clogged up, it's the only way to get the job done. Pull it out. The difference can only be emphasized by the fact that it is not possible to pull out Large in the width of JMCA. "Large and unchanging, down and up. It becomes Exhaust System. It was imaginable before I bought it, and after I installed it, it was just as I imagined.

[About sound quality and volume]
It has a crisp sound like a single cylinder, but the sound here is a little different from what I imagined. Even though the sound is higher and louder than OEM, I can't feel the increase in speed. The sound quality may be a little similar to the Spatras that were popular in the past, and the SR and TW had a similar sound.

【Review】
Because of the low engine displacement volume of 125, it is not possible to get into the flow of the car unless it is revved to a high rpm. I don't know if the reason why the silencer is made of steel is because of the cost or because it is the best material to achieve the performance. I don't know if it's because of the cost or the choice of material to achieve the performance, but it seems that the cost and the performance are good.

[Note added]
I don't know if it's because of the slightly different materials (Stainless and Steel) or if it's a structural defect in the joint, but I've had exhaust leaks and the car body has been dirty. However, the exhaust leak was prevented by adjusting the band position and applying a larger torque than specified.
