【SP Tadao】POWERBOX pipe Review

I liked it so much I bought it immediately.

I purchased the parts I needed, referring to the reviews and videos. There were cheaper stores than Webig, but I decided to buy from Webig because they answered my inquiries carefully and I had a good impression when I bought YOSHIMURA's Exhaust System last year. I was very happy that the delivery was much quicker than I had expected.
Removal and installation were easy, but an unexpected accident occurred:one of the screw threads on the bolt holder on the engine side was crushed.
The torque has been increased, and the driving has become much more enjoyable.
It was Polished Stainless Steel and it looked good once it was burnished. View detail

Maybe it works.

[How is it used?
Touring Main.
Was the one you received as per Image?
Street Image
Was the installation difficult?
Leave it to Shop while you repair it!
How was your experience with it?
I feel that the Motorcycle has become much more honest. I don't feel a drastic change, but I feel that the power increases smoothly with less jitteriness at low rpm. (Lol) I'm not sure if the Torque is higher than it was in NORMAL or not. But obviously the Torque is higher than in NORMAL, and the Speed goes out in a similar RPM range, so if you don't weigh yourself, you might get Large weird.

Parts that can be liked or disliked

Used for 2023MODEL8BL and Exhaust System is SC.

Rucksack is now more like a parallel twin than a VTWIN.
Torque is Fee Ring aligned from Large grains to Small grains.
If you like the sloppy, sticky feeling of OEM, it might be a little hard.

And the exhaust noise is a little quieter.
It also makes a lot of noise on the front bank side.

But it is clearly Torque out from 3500~.
The speed ride is clearly faster.
Driving in the partial range is also quite easy,
Control at very low speeds is also improved.

Tadao indeed! I like it. View detail

Installed on both crf250l and sv650x.

I put it on my crf250l and clearly felt the Torque up, so I put it on my sv650x.
First, the sound has changed. I think it is slightly lower and only the exhaust note is audible.
It's a nice sound. By the way, the Exhaust System is Delke Big.
Also, I'm not sure yet, but I think Torque is also going up because of the sound.
And BackTorque seems to have decreased.
I am satisfied that the sv650x was just right for me as it was too embellished for me. View detail

Considering the price.

I installed it on a ’21 2BL-VP55B.
It was easier to remove the Normal pipe if the parts other than the Bolt to be removed were also loosened as described in the Instruction Manual.
In terms of work, it took less than an hour and there were no problems,
The Gasket attached to the Connector side of the Normal pipe was probably going to have to be destroyed to get it off. The Gasket attached to the connector side of the Normal pipe was not likely to come off without destroying it,
It is better to prepare the Exhaust System separately instead of reusing it as instructed in the Instruction Manual.
I used KITACO's Gasket for both the work. (JPS-3 and XS-06) was already prepared.

Also, although unrelated to this product, the normal bolt was badly rusted, probably because it was made of steel.
I felt that the Exhaust System side, in particular, would not come off after the next grinding if reused, so I later replaced it with a Stainless Steel Cap Bolt of the same diameter.

I think the effect is generally what everyone else has written about.
Silencer is NORMAL, so the sound does not change, but in the mid-low range, the Engine Displacement Volume is slightly increased? I have an illusion that the Engine Displacement Volume has been slightly increased in the mid-low range. I also feel that embellishment has been reduced.
I wonder if I can see the difference at high rpm if the back is also changed, but I can't see much difference with the normal silencer.

To be honest, I felt the construction was not very beautiful,
Considering the price, it's a good idea.
The price fluctuation is large and the delivery time is long when there is no stock. View detail
