Black, light and quiet.

I was not particularly dissatisfied with the OEM Exhaust System, but I happened to find the Exhaust System development blog, and I was browsing it with interest, as the parts that tended to be a little jerky were connected pleasantly. I was browsing the Exhaust System development blog with great interest.
I was told that delivery would be around July, so I waited patiently and was impatient when it arrived right away, but I had time to install it right away.

The Instruction Manual for installation instructed us to remove the lower bracket of the Radiator, but I think it would be easier to remove the upper bracket as well.
*Work is easier to reach and work from the Left Side, mainly with respect to the direction of travel.

BoltQuantity under the belly after removing the Bolt of the Exhaust pipe.:The OEMExhaust System comes off with 2pcs, but if you don't have a Jack or foot under it to support it, it will bottle up and fall off.

If you follow the instruction manual, there is no problem in particular, but if you fix the Exhaust SystemBody first, you will have a hard time connecting each exhaust pipe and the assembly part, so you should put some dustcloth on the wood or jack to prevent the wound from sticking. I think that it might have been better to put dustcloth on the wood or jack so that it can be moved back and forth with the Exhaust SystemBody supported, and then insert it into the exhaust pipe, while looking at the Exhaust System that was damaged by hitting various places while supporting it with my foot. I am thinking about it while looking at the Exhaust System that was damaged by hitting various places while supporting it with my foot.

I have only done some light driving around the neighborhood, but it was easy to ride with Torque coming out from low rpm.
However, the characteristics of the OEM exhaust system have not been changed from the OEM exhaust system to a larger system, and the volume is not bothersome, so even if you ride a long distance, you will not get tired of the sound. I don't think I will get tired of the sound even if I ride long distances.

Exhaust systems for the New Model MT-09 have been available from overseas, but we think this would be a very good option for those who are concerned about the design, which would lose the sense of compactness that had been settled under the belly, and the non-approved parts. View detail

POWERBOX Stainless Steel Full Exhaust System

power box exhaust pipe 2

Fits: YAMAHA WR250X, YAMAHA WR250R

Torque will increase.

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

POWER BOX SUS Slip-On Exhaust

Fits: YAMAHA XT250X, YAMAHA SEROW250, YAMAHA SEROW250, YAMAHA XG250 TRICKER

5/5

It's a staple in SEROW.

[How is it used?
I bought this to change the silencer on my serow 250.
I had already replaced the exhaust pipe with SP Tadao's one, and the exhaust pipe alone was effective.
I also decided to change the Silencer because I felt it was clogged in the high RPM range.
I thought about other Manufacturer, but I decided to use the same Tadao.
Was the one you received as per Image?
This time I chose Stainless and it was beautifully made and well packaged.
The shape of the silencer is also different from other manufacturers.
Once installed, you will not feel any discomfort.
Was the installation difficult?
The instructions included with the product are very detailed and easy to replace. The installation screw holes are perfect.
You can see that it's properly made.
How was your experience with it?
The engine has no stress from bottom to top.
It was a fun Engine.
I feel that the accelerator operation at low speed has become severe because the response has become better.

POWERBOX PIPE

Fits: HONDA CRF250RALLY

Japanese Webike user

5/5

Feeling good was real.

I switched from First Model Type, but I installed PowerBOX on First Model Type as well.
Because the valley of 5000rpm disappeared and I was able to ride pleasantly, I waited for this time and installed it. Even before I installed it, New Model, intake Cam was changed and there was a low speed Torque, and the valley of 5000rpm was not bothered, and I thought that I did not need PowerBOX, but when I looked into the HP of SP Tadao
The contents to develop for RALLY50 were described.
After reading every development article, I wanted to have it and installed it.
I'm sorry for the long preamble but this is how it happened and I drove it today. The engine displacement volume is increased by 30cc, the torque is increased above 5000rpm and the car speed is increased by 10km than usual. I was able to drive at about 70km/h in 6th gear with only accelerator operation on a country road with gentle up and down.
I am Large happy with the performance and look for a small expense.
As a side note, the exhaust pipe of HRC's Motocrosser was equipped with a tube similar to the powerbox made by Yoshimura.
One more ad-vise when you install it by yourself, if the O2 sensor is very hard when you remove it, you should have it removed at the shop where you bought it.
In my case, I managed to remove it while spraying lubricant, but the threads of the sensor were crushed. In the end, I couldn't install it and it took a lot of time to get it replaced under warranty at the shop where I bought it. View detail

POWERBOX Full Full Exhaust

Fits: KAWASAKI Ninja ZX-25R

4/5

Certified products:？？？？？？

At NAPs Yukiura, we test rode the ZX-25R with SP Tadao Exhaust System, and our desire doubled.
I was patient, but I couldn't resist and bought it.
The installation was done quickly, but the Instruction Manual was easy to understand, and the removal of the OEM Product & SP Tadano Exhaust System installation was completed without any particular problems.
Gasket was prepared in advance, as it was better to replace it.

The replacement work of Exhaust System is only work of 8 Nut of Exhaust System and Bolt1pc. of Exhaust System exhaust pipe part.
Cowl related, too, when Right Side was removed, it was possible to work, and there was no particular obstacle.
Even if you work slowly, you can complete it in 2 hours.

I applied the engine and it worked fine, and that was it for the day of the exchange.
The next day, in the morning, I checked the tightness of Nut and Bolt and started running without any problem.

Since it was warmed up, it was a little noisy, and it started running.
I get to Route 134 and, well, I open the Axel in earnest and it's deafening to me and the sound is LARGE and LOUD!!!!
Is it like this? So I spent a few days to check it.

I don't like the loudness of the bike, and I'm thinking of selling the whole bike. What an idea ・・・・.
And in time, I was able to confirm on the Net that GoldSponge would change the noisy sound of the Exhaust System.
So, I decided to use Gold Dashi, which was not the method you recommended, but because of its shape, it seems that it won't slip out if I stuff it into the exhaust pipe.

When I told my wife about the Gold Dashi, she had a Small one and I packed it up as soon as possible.

Then, the sound quality which was grating became good, and I did not feel noisy though I think that the Largeness of the sound did not change.

Now, it runs good. The sound quality is good, too. Oh, good.

And the performance, especially the large change, I may not know. View detail
