【SP Tadao】POWERBOX FULL RS FULL Exhaust Review

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

I feel good! is this!

[How is it used?
Intake, ECU, and Plug are in NORMAL condition.
Review after driving more than 300 km after installation.
I have no complaints about the OEMExhaust System, but I fell in love with the look and concept of this product.

Was the one you received as per Image?
Exhaust pipe - Exhaust System1 pc mono, arrives well packaged.
Material:Polishing is beautiful. It is hard to get dirty, but I like the brown burnt exhaust pipe, so I will not take care of it.
Black weld residue was on the end of the car. I blew it off with a stick and parts cleaner. I am not particularly dissatisfied with it.
Sticker is the Quantity:1 pc. Attached

Was the installation difficult?
It came with an easy-to-understand instruction manual.
As with the OEM, this is a single piece, so the screws are tightened while holding down the front and back. Lay the product's step ball on the floor as it is so as not to damage it. Be careful not to hurt your back.
Gasket used OEM new equipment.
I don't like Liquid Gasket, so I applied a thin layer of YamahaGreaseB to the OEM Gasket and stuck it to the Engine.
Each Torque referred to the Service Manual it had previously.
The bolt on the chamber side was hard to tighten, but I put the included RibbedLock washer here. So far, there is no loosening. I am impressed with the cost of such a small detail.
BabyfaceRear Sets for MT-07 were also added.
SW Mo TEC's patented Center Stand was removed at this time because we wanted to save weight, but it could be used together.

How was your experience with it?
I have not weighed it, but it feels lighter when causing, handling, and driving.
When starting, I feel as if the Engine Displacement Volume has been increased. I don't feel like stalling. Torque up at low and mid RPM, and the engine starts to blow up lightly. It doesn't feel jerky even when going up to first gear on the usual road.
With the OEM system, there was a vibration and a noise that seemed to cause the engine to stall at speeds below 3,000 rpm in 6th gear, but with this exhaust system, the engine flows smoothly and smoothly.
The volume is the same as the Japanese Vehicle Inspection Correspondence, but the sound quality has been changed and the bass is more effective. Actually, this product has two exhaust outlets and a hole on the underside of the chamber, which may be a reflection of the OEM exhaust system of New Model 09. 270 degree Crank is also included to make it sound like Harley when it is used with Blip Pingetc. It is good. AfterFire is appeared when ThrottleOff, but it is not abnormal Level, so I leave it as it is because it is good parenthesis.

[Opinions and requests to Manufacturer
I want full titanium for 07 series. On the other hand, if it is released now, it would be Shock (lol). View detail
