Very Good
Cost performance is good, but there is no large performance change.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.View Detail
