About the PowerBox for CRF250L MD47.
I installed the PowerBox for CRF250L which was released recently.
I had a hard time installing it because the pipe diameter of the product and the OEM exhaust system is too narrow. (Well, maybe I'm personally not very good at installing them.)
It feels like the torque is increased after 4000rpm.
Also, the exhaust sound seems to be a little lower.
I think this is a good product that can easily Torque up the Engine Displacement Volume of 250cc.

Royal Road Parts for WR250R/X
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.

Not consistent with YOSHIMURARS-4J, for FMF or OEM Exhaust System only.
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.

Torque is lush! Is it resonant when accelerating at high speed?
I chose Stainless Steel Type because I liked the calm feeling.
I bought the POWER BOX without hesitation because I had installed it on my CRF250L before and could feel the effect.
The torque at 4500-6000 rpm is very good. 90km/h is very good. Acceleration from there is also very torque-like, and at the same Axel opening, you can get about +10km/h. However, there seems to be a resonance when accelerating from about 90km/h. I think I should increase the band of Silencer.

sp Tadao sus & carbonExhaust System and SEROWDj17
It is the same length as OEM, and it is Stylish. I was not sure what to do, but I bought it with confidence because the owner of serowOnly vol6 has a lot of installation rate. The installation needed a tool in a certain way. The sound becomes a little large, but it is okay if you get used to it. I can cruise 100km with ease. The fuel consumption became terrible, too, recording 55km/l in Touring. It has become a different thing from the normal muffler of the new car's own normal motorcycle. View detail
Just the right volume
The sound quality is good and the volume is just right, although some people may feel it is not enough.
This is not a bomb, and even if you go touring, you won't get tired of the sound at all.
I can't tell the difference between Power, Torque, and Curve at all.
You can install it by yourself if you can do the usual maintenance.

A SEROW classic!
I installed this on my second car following the SEROW I gave to my son.
It's no longer a staple in SEROW.
I hadn't worn them in a while and completely forgot about them, and I was a little concerned about the way they felt against my Right foot because they bulged outward more than I expected.

One more step & hellip;
It's one piece, so there's no way to go wrong with it.
It's been a while since I've installed a One piece Exhaust System.
It was a Large difference from the old one and it mounted perfectly like OEM.
The volume is much braver now, which is nice!
It also has more power in the low and mid range, and the feeling of revving up to higher RPMs at once, which I think suits the character of this motorcycle.
However, even though it is so good, there is a problem in the processing after the assembly section, and the bank angle is reduced.
I've never even grounded a footpeg Knee Slider.
I grounded it and scratched it after 10 minutes of test running after installing it…
This is a shame because the characteristics and looks are outstanding.

Short Exhaust System without Lunch Box
I did the install myself, Torque is Flange nut 12N, Exhaust Bracket 20N.
I'm not sure if Gasket part number 11061-1372, 38.4mm O.D. and 33mm I.D. is Universal Product compliant.
It is easy to understand because it is written from how to remove Cowl in Instruction Manual.
Flange is quite cramped, so it is better to have Extension and Universal.
It weighs about 4.4kg and is lightweight because it is a Short Type despite being made of Stainless Steel.
Because there is exhaust end under the escape of the Swing Arm, it seems to interfere if the Swing Arm of the outside straight shape comes out in the future.
The sound quality is satisfactory in the feeling that the bass sound became stronger than OEM, and it became quiet when it ran for a while whether the correction came into effect though it was crackling as much as Miss Firea Ring at the time of the shift at the beginning of exchange.
The running fee Ring has no longer the feeling of being stuck in the trough of the Torque around 8000-10000 and it extends beautifully from low to high RPM.
If you like the feeling of the song rising up from the depressed Torque, you may find it lacking in intonation.
I did not feel a sense of luxury in the finish with the weld burn of Stainless Steel as it is, I think that point is TradeOff because it is cheap and performance is good in the Full Exhaust System.

Great buy, used on a 2019 YZF-R25.
OEMExhaust pipe and Slip-on Silencer of other FOR JAPAN MODELManufacturer (JMCA Certified of course) I had installed the Full Exhaust SystemQuantity to improve the volume and the fee Ring a little more, although I was satisfied with it at first.:I was considering purchasing a Set. However, there was not the one of the preference that I wanted such as Design and Manufacturer. In such a situation, I bought it because it was a solid thing when I knew from SP Tadao that there was Exhaust pipe that could be used on a public road and examined it.
Pipe becomes thicker than OEM, and it seems to be able to expect a high rpm range from more than 6000 rpm. Because it was the Level which did not become a neighborhood nuisance by the warmth with a small change in the volume in Idling, it is saved. In addition, even in the Idling stage, I notice that the exhaust pressure from Silencer has increased like Large, and it makes me feel expectation. The low speed torque at the time of 0 start seems to have fallen a little, but it was assumed from the Vibe diameter, and it accelerates mildly in town driving, and I think that it is set up well so that it is easy to handle. It is the Sub chamber that SP Tadao is good at, and the volume has been suppressed. The volume increases, but I think it is good to buy it because I can taste the bass sound more within the specified value. I wanted to modify the rev limit by 500 rpm with ECU because the change with the characteristic was shown. The PowerBoxPipe seems to have a good reputation also for the person who runs the course with the Off car.
The price is not cheap, but the recent domestic Exhaust System certified Full Exhaust System is the quantity with Titaniumium silencer.:I think that it is reasonable when I subtract the silencer part because it is the time when 100,000 yen or more is commonplace in Set. Rather, when it becomes SP Tadao, it is a price which is easy to buy further. Even if the price becomes even higher, I want you to release Titanium bar John like Large type Class.

Low-speed TorqueUP
Installation is easy
I installed it expecting to increase the torque at low rpm.
Maybe because my expectation was too large, it was like this? It's like....
However, the Torque feeling has definitely increased.
It may change depending on the Silencer you combine.
I'm currently running it on OEMSilencer, but I plan to replace it with FMF sooner or later.
I was able to install the Heat Guard with no problem in the OEM orientation.

Added low-end torque with quality to match
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 bundled View detail
Slow Torque you can feel
[How is it used?
Forest road and mountain play sometimes Course
Was the one you received as per Image?
The quality of the product, including the welding, was better than I expected.
Was the installation difficult?
The accuracy of the product is good and I was able to install it without any difficulty.
How was your experience with it?
First of all, when I installed it, Torque started up immediately by opening it from Idling.
I found that starting the car was much easier.
Secondly, I feel that the engine is more sticky at very low speeds, climbing gullies, etc.
Throttle response will be a little dull, but in the mountains, this is the best way to reduce energy consumption.
However, when you are playing with FlatDirt and swinging the rear, you will feel the dullness of Response.
[Included Parts:were they on?
It came with no excess or deficiency.
[Was there anything that disappointed you?
None in particular

Large human volume
I had YOSHIMURA but it was too noisy, so I installed this one as my last hope. The sound is very quiet and I can run it at night in a residential area without any problem. I am satisfied with everything except the high price. View detail
No Demerit
I've always been curious about SP Tadao's "PowerBoxPipe I finally installed it on the final fifth and final XG250 TRICKER after taking over the SEROW & XG250 TRICKER series.
Since it is only the change of the exhaust pipe, there is no dramatic change in the whole area like Full Exhaust System, but if it runs all day, you will get used to it, but at the place where the corner that can run continuously while enjoying acceleration and deceleration at 40-70km, it is just the right thing to do. Feels good! You can feel the acceleration.
The effect may not be felt depending on the situation such as continuous running at a constant speed, but it was a good purchase that further upgraded the SEROW-XG250 TRICKER system with high sensitivity even in NORMAL.

reasonable in price
SP Tadao has always been a motorcycle dealer in Yamaha, so I bought this bike.
As the name suggests, the Tune upExhaust System as loud as NORMAL? I think.
Especially the middle acceleration!
It is reliable.
However, the price is about 2 to 3 times higher than other companies.
I think it's overpriced, but a bit pricey.
If I have a complaint, it's the rain puddle in the exhaust section. (Lol)

"Weighing in without sacrificing speed. Then this Exhaust System
2.4kg (3.2kg can be weighed) compared to 5.6kg for the OEMExhaust System
3,000 to 5,000 rpm; clearly more powerful.
From 5,000 rpm and up; you can't feel any cleavage and it spins easily.
Although the Speed ride seems to be slightly better.
Maybe it's just my imagination because the sound is changing and so on.
At least it's not worse than the OEM.
I saw in the other imprecation that Clearance was a fewmm.
My body (2019) has over 10mm of Clearance on my body (2019).
Interference and other issues seem to be fine.
If you like the look of it, it's not a bad buy.
However, the Exhaust System is It's too loud. I do not recommend it if you are not a fan of this product.

Was good
2020.In early September, I replaced the YOSHIMURASlip-on Silencer that I had been using until then.
Difference 1. Yoshimura...The sound around 3000 RPM is very comfortable. SP Tadao...The sound around 4500 RPM is very comfortable, so I tend to open a slot. 。 I don't feel much of a difference under 3000 rpm, but I think the SP is a little drier and the Yoshimura has a more refined sound.:I'm very happy with the sound of the SP over 4500 RPMs, which is much more to my liking. 。 I still get caught up in turning it around. You have to be careful. 。 However, the eyeball emblem that was recently glued on (as it was when I bought it) has come off! 。 Eh! I thought it was an adhesive, but it has a problem with heat resistance. I bought a two-part heat resistant adhesive (Made in USA) at We-Big. Hohoho...
I am not too concerned about the appearance, blow-up performance, etc. because I am satisfied with Large...

Take your pick.
I installed it after the PowerBox (PB).
I replaced it with a lighter one as well, since I started to worry about the gap between the 6,000 RPMs that was improved with the PB and the 7,000+ RPMs that were fine to begin with. So I changed it to lighten the weight.
The volume and sound quality, which I was worried about, is not too loud and just right.
The company's website describes how they struggled to match up with PB in the development process. Personally, I think that after all this cutting and pasting and trial and error Yeah, we got something. That's what I love about the Large, so I'm happy with this story and the lightness of the product in my hands alone.
for that reason "Race Specification out and blasting. And "Carbon and titanium makeup. I'm not sure if this product, which has no

Sound quality is bass, volume is moderate, design is good.
I replaced the 2018 DG31J with the company's exhaust pipe and then additionally replaced it. It was hard to find a good fitment, but DG16J, DG17J, and DG31J all fit.
The build is very good and installation is effortlessly perfect. The sound is low pitched, not the pattering sound that is common with the Exhaust System on Off cars, and the volume is modest as per the Catalogue. The warmth is large and sturdy without much care.
The extension of the high RPM is better, which is good for touring use.
I was worried about the clogged design, but when I installed it, it felt strangely good.
