【SP Tadao】Power box exhaust pipe Review
To the price price
I am in good shape.
It is thicker and longer than OEM
Combined with the external exhaust system, I had a hard time installing the PowerBox so as not to touch the Crankcase
Performance is Image which makes Torque's regulation uniform when opening Axel
Specifically, it keeps the Torque constant regardless of which throttle opening you open
Combined with FMF's Exhaust System, I was able to experience the above changes finally after lowering the Sprocket of Front
Be careful when combining with a missing Exhaust System

Easy to install
To begin with, I bought it for replacement for an OEM that looks rusted and battered.
The product itself can be installed without any difficulty, but I tried to replace the stud bolt because it was a good opportunity,
It still broke and Shop took care of it.
I am happy with the way it looks and the way it is attached to my car.
The most important thing is the effect, but I have run about 30 km and I don't feel it….
When you say it, it is like a smooth Speed ride.
Scattered bells could not be heard.
This time, I am satisfied because the appearance is important to me.

Magic tube
PowerBox is a popular choice for not only CRF250rally but also 250cc Single.
From the start, the torque and acceleration were clearly better than those of the NORMAL, and the mid-range acceleration was also without any stress, giving the impression of a 300cc class cruising capacity.
The sound has also changed from a caged sound to a crisp and refreshing atmosphere.
It feels so good!" The magic tube, not the magic wand, that turns Motorcycle into a Motorcycle and casts a spell on Motorcycle
Considering the price and performance, I felt like running anywhere Reasonable forever.

Speaking of CRF, this Exhaust System
Speaking of CRF!
It is easier to ride because I no longer feel like stalling at low speeds in first and second gear.
I don't know if it was only the effect of the Exhaust System, since I changed the Silencer at the same time, but it was good anyway.

This is good...?
SP Tadao used to run SDR with Jackal Chamber. Silencer is equipped with SP Mukawa's Cone Oval Exhaust System.
I am removing the exhaust pipe for the first time, so it would be helpful to have an instruction manual. It is also nice that the pictures are in color. This time we are using an external silencer, so the outer diameter will be different.
I assembled it without Gasket, including the first match. The first time I assembled it without Gasket, I felt the exhaust air escape. I immediately applied the liquid Gasket that I had prepared. It is better to prepare it in advance if you are going to change to an external exhaust system.
I have previously installed an external exhaust system on another motorcycle. The heat from the assembly burned and discolored the lower part of the under cowl. This time, I had enough space for a single cylinder, but I put aluminum tape on the side cowl just to be safe.
The Silencer is not NORMAL, so there is no comparison, but I think it shows the effect of the POWER BOX. Normally, when you replace the silencer with an external silencer, the exhaust sound is better than the normal silencer. The exhaust sound becomes louder and the torque drops as a result, but when the power box is installed, the torque drops less than expected in terms of exhaust sound.
When I turn it up to 4500 RPM, it makes a gurgling sound that belongs to the Gold family. When I was running another motorcycle with an external exhaust system, the spring that came with it started to make this sound. It is similar to the sound I heard at that time. This time I checked the Exhaust System and Silencer to make sure there was nothing wrong. I believe this is the chirping sound that was described in the instruction manual. The sound quality reaching my ears changed and became weaker when the Cowl was installed. After that, I have been using it for more than half a year and there is no crack. There is no discoloration of the Cowl due to heat. There is no discoloration of the Cowl due to heat.
I felt that Overall, the ride has been easier." I think it's even more amazing if it's NORMAL. I think NORMAL would be even more amazing since I can feel it even with Silencer outside the company.
At first, I wondered how it would work on a single cylinder when I saw the exhaust pipe popping out of the box. If you want to replace the exhaust pipe with other brand product, I think SP Tadao's POWER BOX is the best choice.

Ease of handling up!
The motivation for purchasing 19MRALLY50 was Ann Label's
I wanted a RALLY50TrekExhaust System, so I replaced it right away.
Normal muffler is not very impressive, but it has been around for 2 years.
I got on and started driving in the woods from time to time, and the low RPMs were not too much.
I installed PowerBox because it is not Smooth
I can't get rid of the Down Type Exhaust System, though.
Replaced PowerBoxPipe+Normal muffler
My first impression is that, as expected, low RPMs are now available.
Long our GEAR ratio (15-39) I've been working on it for a while now.
It was jerky and unusable below 4000 rpm, but after the replacement
It can be used at 3000 rpm for light loads and when Axel is opened.
The feeling of moving forward has increased.
From there, it will turn to Flat until 8000 rpm, so
There's no sense of excitement, but I get the impression it runs on Torque.
Conversely, the RALLY50TrekExhaust System is a low RPM Torque
Moderate and loose, good extension from 6000 rpm.
It was fun to turn it because it felt like
The sound is OEM exhaust system, but the bass is strong and crisp.
It's comfortable even in NORMAL.
Naturally, it's not noisy and you can run peacefully and mentally.
It was fun to run at a leisurely pace (lol).
Well, it's also a commuter car, so I'm happy with the practicality of it.
Pipe replacement is a Motoskill Crash Bar.
It is not possible to install it with the ring of wisdom when it is still on….
I had to Rose them all, so that was the only hassle.
