Выхлопная система BEAMS SS300 для YAMAHA JOG ZR

Nice and beautiful all Stainless Steel the sound is good the egine is blowing better than before and with pearing holder.and what the mosst I like is made is the quality.

I fitted the exhaust to a 2007 APE50 FI, the style is good & the fitment easy. I ordered the semi race baffle as an extra which was also easy to fit. The sound is nice for a 50cc single cylinder, not too quiet & also not too loud. I think the Beams SS300 is a good midrange priced exhaust, which I would buy again.

This was the first time for us to replace an existing exhaust system.
The work station time was about 30~40 minutes. I don't think there were any particularly difficult Points.
The construction as a thing is very beautiful. There is nothing cheap about it, and it looks beautiful.
Baffle is sold separately, Semi-racing baffle is used.
My impression after using it is that it has more extension at higher rpm than before, and I can feel that the power has increased in that area.
However, the Torque feeling at low rpm seems to have decreased a little, so the power output has probably changed to a higher speed driving style.
The sound quality, partly due to the Baffle, is now lower and more resonant than before. The volume is also a little louder, which may be a little annoying when driving in residential areas at night.
Overall, I think it is a good product, and if you are a Custom beginner, you can't go wrong with it.

It looks good and sounds good. More importantly, the engine now blows better and revs higher. Because of this, I feel that the maximum speed in each gear position has increased more than 10km/h. The effect is very Large. It was the right answer to change Large.
Without the Baffle, the sound is very loud and you can't hear the engine sound at all, which is definitely annoying to the neighbors because the sound quality and volume is so good that it's hard to believe it's a 50cc engine and a CUB. (Lol) You can't Engine early in the morning.
When I put on Standard Equipment's Standard baffle, I can hear the engine sound very well with almost the same volume as the OEM Exhaust System when starting and idling the engine. When I run the engine, the sound quality is good, but the volume is a little larger than OEM. In fact, it is easy to use because I can open Axel without stress in the town.
If I change to Racing baffle, the volume will be higher and it will be more fun on the mountain road. I don't know if I can use it or not. "Not installed on LITTLE CUB." The answer was "yes", so I am a little hesitant.
By the way, these differences seem to be the difference of LargeSmall of the exhaust pipe diameter mainly.


≪Impression.
[OEMExhaust System Sprocket is OEM (F14T・R39T)
It is not impossible to run at 30km/h in 2nd gear on level ground, but it is difficult to cruise because of engine noise and vibration.
On a gradual uphill slope, the car will not accelerate past 30km/h in 2nd gear, and even if you force the car to go up to 40km/h, which is the upper limit of 2nd gear on the Speedometer, the ShiftShock will only be Large and the Speed will not increase.
Neighborhood public road testCourse (Lol) When I tried cornering at over 40km/h on the gentle uphill LeftCorner of the hill, I raised 2nd gear to 3rd gear at 40km/h before the corner and rammed it, but the GEAR ratio did not match the engine output and it stalled immediately. In other words, I can't go over 40km/h on uphill.
Even when going downhill, if you go over 40km/h in 2nd gear, the engine will not turn, so you have to go up to 3rd gear. But at the start of the corner, if you keep the engine in 3rd gear, it won't accelerate because it doesn't have enough horsepower. But when the speed is over 40km/h, I can't drop to 2nd gear. In other words, Rhythm is too bad.
As a result, the GEAR ratio and Engine RPM don't match at all on hills, so if I continue to increase the Driven Sprocket tooth speed, it will be even worse because there is too little Torque.

[BEAMS Full Exhaust System] Sprocket is OEM (F14T・R39T)
Acceleration from 30 km/h to 40 km/h in 2nd gear, both on level ground and uphill (How to increase Engine rotation) The GEAR ratio is still the same as OEM, so I felt as if I shifted the Peak horsepower generation rpm and Red zone to the high rpm side just by changing the exhaust system. The way to work (Flat road) There is a road with 30km limit in the 2nd gear, but this exhaust system has made the high rpm range of 30km in the 2nd gear also the limit normal use range.
By the way, I'm cruising in 3rd gear at 30 km/h in the mid-range, and I have plenty of time to accelerate out of the 30 km/h limit in 3rd gear.
The pickup of the engine is improved and it blows well, especially the high rpm side becomes very extended, and the ShiftShock when I raise it to the third gear in the rev limit range over 40 km in the second gear becomes much larger than the OEM exhaust system. It became considerably larger than OEMExhaust System, and the acceleration became slow. If the speed is maintained and the rpm is lowered a little more, the torque will be thicker and the acceleration will increase.
The rev limit has been increased so that I can get out of the corner at 40km/h in 2nd gear, and even at 40-50km/h in 3rd gear, the acceleration at the start of the corner has been improved, so downhill cornering has become more fun. It will be interesting to see what happens when I increase the number of Driven Sprocket teeth.

Really good finition as always ! But note that if you get a muffler just for the stylein every case you might need to get a cdi, otherwise your bike will loose speed !as well air filter might be recommended since your bike will put out more air that it receive.The last part If you want lowder sound i recommande you to get the semi racing baffle which will give you a soft sound. I dont know why i always expect the sticker to be stick on the muffler at first. I guess thats the final touch when its well setup. Anyway Enjoy
