Exhaust System with a palpable effect

I had installed JOSHO1 Japanese Government Approved Exhaust System, but it only changed the sound and did not lead to speed.
The exhaust system of the scooter is only the one that the performance doesn't change even if it exchanges it, or the one that the low speed becomes scuffed up by the exhaust system becoming good, but since I could feel the effect by using the product of SP Tadao in WR250R, I bought the exhaust system of CYGNUS Glyphus. I bought CYGNUS Glyphus Exhaust System, too, although it is expensive.

We recommend that the O2 Sensor be removed after the Helmet is removed.
I was wondering about the sound of SP Tadao's Youtube because it sounded SMALL,
After the replacement, the engine sounded good even though it was a recognized exhaust system, which was a pleasant miscalculation.
When I started to run, I obviously Torque up and grinned.
This is very helpful because it involves getting through one traffic light on the way to work.

The drivetrain is a JOSHO1 Pulley, WeightRoller 8g, from OEM.
Since it is a Spec. that rotates the RPMs, I think it would be even better to leave it in NORMAL to experience it further.
We are currently using OPRACING Clutch and Torque Camshaft. View detail

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. View detail

POWER BOX Exhaust Pipe

Fits: HONDA CRF250 RALLY

5/5

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. View detail

POWERBOX FULL RS FULL Exhaust

Fits: YAMAHA MT-07, YAMAHA XSR700, YAMAHA YZF-R7

4/5

2023.Since November, YZF-R7 (YZF690) The system is also compatible with the

Purchased at the Yahoo! Shopping store.

At the time of writing this impre,
The only information I have is on the development blog of the producer, SP Tadao,
In fact, this Exhaust System will be available for the YZF-R7 from November 2023 production.
I tried to install the previous production and could not fit the Cowl,
Spec. has been changed so that they can be installed.
Since it is officially certified as a compatible vehicle model, the Gas Repo documentation is of course included.

First, regarding installation,
Although it adds the time and effort of detaching and attaching Cowl,
I think it is generally the same as the installation on MT-07 and XSR700.
Accuracy is not a problem, though the shape is very OEM-like with a so-called lunch box,
Clearance, etc. were no problem, and it all fit together smoothly.

Flange bolts are often a problem when installing an Exhaust System for Motorcycle,
In this R7, after removing the Radiator Bolt and floating it,
By removing the Radiator fan and staggering it inward,
I was able to get Space to use Torque wrench without any problems.
Clearance with the bottom squeezed Cowl section is also fine, as shown in the photo.
Insulation Sticker for R7 is also included.

Next, let's look at sound quality.
I think the MAJOR ones for R7 are around AXIS Lapo and Over.
I have only seen these Exhaust Systems on Youtube videos,
I have never actually heard of it,
My personal impression is that AXIS Lapo Vine, vween." The sound of the Gold genus quality is Main.
Over. Vloroong, vloroong." And so on
I feel that the sound quality is like a Normal muffler sound with a burst of sound that adds power to the sound.
However, the actual impression of the Exhaust System installed this time was also different from the video I saw on Youtube,
The above impression may differ from the actual situation.

Actually, this is my impression after listening to the actual product,
The sound quality is different from the above two types, perhaps due to the special shape.
The sound quality is more bass-like than the AXIS Lapo, which seems to have cut the low frequencies, but it has an over-like bass,
The sound quality is more bass-oriented than that of the Over, or rather, the sound quality is like a high-cut version of the Over sound.
When you turn it, it is as if there is no Gold genus quality, it is as if it is crawling on the ground. "Von, von." It sounded like "I'm sorry,
I used to drive a Panigale before,
It sounded like a sensible (?) version of Ale's Normal muffler. I felt it sounded like a sensible (?) version of the Normal muffler.
After all, the current car has Corresponding Exhaust and the sound of the engine itself is too different from that of Panigale,
It is not the same, but it is pleasant for those who like that kind of sound! It may be.
In fact, there is also an exhaust port under the Exhaust System, which reflects the sound to the ground, which probably helps.

Finally, there is the all-important performance aspect.
Frankly, it is a waste of time for Gold to think about things like the most Large output in today's car inspection Corresponding Exhaust.
Furthermore, the Exhaust System was not developed with this as the primary focus,
I didn't get the impression that Top End's power was increased or anything like that,
I felt a definite improvement in the driverability around the mid-speed range, which is what I was aiming for.
And even if I skipped Shift more than usual, it was easier to just flow with Axel,
That Torque fully turned mid-speed coupled with that sound of how it feels like it is accelerating in Torque,
The Corner is very comfortable to use! It's a great feeling!
I don't think this is for Circuit people, for example,
If you are a public road person, I think you will be into this characteristic.

Recently, the price of motorcycle exhaust systems has been increasing,
And yet, with stricter regulations, we think about it for the purpose of improving performance,
It has become a cosmetic PARTS by any stretch of the imagination,
I had been holding off on replacing it, but it was worth it to see how it went. View detail
