It is 5 years since I got on WR, but I finally bought it. Since installing also loosens several Bolt and exchanges it with OEM, I think that if you are a little familiar with the work you can install without problems, but if you do not remove the remaining garbage of OEM Gasket on the Exhaust System side well and cleanly Since there is a possibility that Gas leaks after installation, it is attention only there. I am satisfied with the feeling that I changed some sort of appearance after installation. As a ride impression, I was able to feel the change from running. Especially I felt that the growth of 1st and 2nd speed got better and the embreement at the time of Downshift was relaxed making it easier to handle. In addition, I was able to run using Torque up as a whole, up to the sixth speed I did not normally use in skusca. While riding, I certainly feel a fever around sune, I think it's better than Motorcycle with Cowl. Even without buying the Full Exhaust System, it was good enough to buy it because it is affordable and the price is affordable.

The SP Tadao v2.0 is a much appreciated rework of the first version. Now I could use the OEM cover without positioning it upside down. If you want extra low-end torque and a lighter header pipe then this is it. A bit hotter though due to its resonance chamber's design.+Lighter than stock+Low-end torque+Compatible with stock heat shield-A bit hotter-No gaskets bundledView Detail

I installed it with FMF and it seems to have increased low speed!
Both db’s Silencer and I installed OK!
However, since the chamber section has increased, the right foot seems to be a little hotter than the OEM exhaust pipe.
Gold genus sound increases, which may bother some people.View Detail

The silencer was a GruidRide Thailand coon, and the intake diaphragm was removed for full power, and the adjustable fuel conditioner was set to +4.
When I changed from the normal exhaust pipe, the torque increased and the sound became a little quieter. However, you may feel some heat in the right leg due to the expansion chamber sticking out.
You can tell when you are riding in it, but if you buy it and put it in right away, you may not notice any changes.
Please be aware that this is the only change you can expect. However, the effect is definitely there, so if you feel that even a slight performance increase is a very large change due to the 250cc engine displacement volume, I think it is a good buy.
At 25,000 yen, it's not that expensive, so if you want to make your vehicle as fast as possible, I think it's the right choice.
External exhaust systems are usually too large and lose torque in the low to mid RPM range, but this product increases torque in the low to mid RPM range without losing power in the high RPM range.
If you want more power but less noise, this is a recommendation because it is quieter than the normal exhaust pipe.
This is not my story, but I have heard that exhaust leaks may occur depending on the silencer you use, so you may want to check this out carefully.View Detail

I bought it for the purpose of improving my Torque for forest road touring, etc....
If I want to do Full Exhaust System, I want to do it with the same Brand.
I am personally reluctant to combine the Slip-on Silencer with an external silencer, and I like the large size of the OEMSilencer, and I am satisfied with the Silver Silver items that aim to increase the power without hindering the excellent total design of the WR. I am satisfied with the Items.View Detail

Because this one purchased YOSHIMURARS-4JExhaust System additionally to WR250X of my wife's Course running exclusive use car, I combined it with OEM Exhaust pipe and DeltaTorque head pipe and enjoyed it, and then I installed the change of SP Tadao PowerPipe2. The exhaust leak occurred though I installed it in order to determine it firmly. I thought that I could easily cure it from the experience of having done the maintenance, custom, and one-off like the devil to American muscle cars, Harley big twins, VRSC series XR1200, Ducati, BUELL, etc., but no matter what I did However, even if I do it, a slight exhaust leak is not cured.
When we checked our WR250X2007, we found that there was a very small exhaust leak, which we did not notice when we installed it.
I have no choice but to go with a combination of FMF Q4 and SP Tadao for both cars.
It is very disappointing because the chemistry of YOSHIMURA Tadao was great in performance.
I have checked with Yoshimura Japan and they have confirmed that the OEM exhaust pipe and OEM new gasket are the only ones designed and developed. Please check once again. Power loss and Damage to the Engine will be irreversible even if the exhaust leak is very small.View Detail
