Evolution Line (4-2-1) Full Exhaust Exhaust

Installed on a GSX-R1000R 2019

The motoGP GSX-RR has an AKRAPOVIC exhaust system, so we chose AKRAPOVIC instead of YOSHIMURA to match the system.

First of all, I would like to say that GSX-R1000R (2017-) It does not correspond to Japanese Vehicle Inspection. and Don't use on public road.
This time, I decided to purchase the Full Exhaust System replacement for the catalyst damage countermeasure on the premise of Circuit running.

[Installation related
I think it's about 4 hours if all goes well.

First of all, GSX-R1000 (2017-) Due to the configuration of the vehicle, it is necessary to remove not only the Side cowl but also the Seat cowl because the removal of the exhaust device occurs.
In addition, not only Radiator, but also Oil cooler is air-cooled 4-cylinder, so it becomes the model of the part that takes time and effort as Full Exhaust System replacement in the first place.

Because it was the first time to exchange the Full Exhaust System with many joints of this kind, I struggled for a while to install it in the car body after assembling the Exhaust pipe part.
With this method, there is too much freedom in the insertion allowance and angle, making alignment a difficult task.

As for the point, the Exhaust Pipe Flange part can be disassembled.
So, if you remove the Flange part from the Pipe and install the FlangeSingle Body to the Engine first, and then insert it in order, I think you can go smoothly.
Even with that in mind, the Spring assembly of the Exhaust Pipe Flange is the most difficult part, but I can only say that I'm very enthusiastic about it…

It is also necessary to reassemble the rotating part of the exhaust device, but be careful not to break the exhaust device.
The hexagonal part is held in place by a 7mm bolt, but care must be taken to ensure the hexagonal part is secure when removing it. If you try to remove the 7mm bolt directly, the rotating part of the exhaust device will be turned by force and can be easily damaged.


[Feeling of use]
The exhaust sound was a little louder than the OEM Idol with the attached Baffle. It was about the same.
When I turn it, the volume is clearly Large threshold.

Also, when I reassembled it, I really felt it was lighter.


【Included Parts:Related】.
There is a relatively detailed Installation Manual, but it is the English version.
I think you can read it somewhat because it has diagrams.

In addition to the Exhaust pipeBody, there is also a part that physically cancels the exhaust device.
So, for the time being, there is a complete set that can be hung on the Engine.
By the way, you can see something like Wiring in the picture of the contents, but it is an extension of O2SensorWiring.

As a manufacturer, it is recommended to rewrite the ECU when using this product, but I have been using it without rewriting.
I am using it with Baffle installed because of that, but no particular problem has occurred at present.

The joint part of the exhaust pipe and the insertion part of the silencer are both insertion spec. but the gasket is unnecessary.
The application of CeramicPaste is necessary, but this is also included in a small amount.

The Exhaust Pipe Flange section requires the OEM Gasket, which is not included and must be prepared if you do not want to reuse it.


[Was there anything that disappointed you?
Unlike Titaniumium exhaust pipe which has colorful burnt color, this exhaust pipe is purely designed for performance.
The Silencer is finished in Beauty, but the Pipe part is not finished aesthetically, so if you are looking for looks, it is better to choose another one.

What can I say?
I had a hard time wrapping my head around that until I realized Flange was out.
Also, you can't change the oil filter with this product installed, so you may need to remove the exhaust pipe upstream every time you change the oil filter.


[Summary]
I think it's a pretty Stoic product to make.
It in the first place is a racing exclusive parts.
Stoic spec without flashy.
So-so volume.
ECU rewriting recommended
Poor Maintainability (Oil filter replacement is a pain)
High degree of difficulty in exchange (It's too dull to reassemble with OEM every time the car is inspected)
and if you expect to use it on public roads, you should give it up honestly.
But it's also a Large layer to reassemble every time you go to Circuit…

It is the AKRAPOVIC of the world, so you can be sure of its lightness and performance.

but it's not something I would recommend to the general public.

Also, it's Made-to-Order, which means there's a considerable wait time after you place your order.
I waited about 4 months.
When you need to order, you need to order well in advance.

There is a considerable difference between watching the movie of the person who installed it and actually listening. It was a powerful sound and it was quite a blast.
I am running with my mind in the neighborhood
As bass sounds like it feels comfortable running, it is Large satisfied!
Installation was quite Large strange, I had little knowledge, I worked alone in an amateur and it took 8 hours. However, I think that I do not regret it because it is sound quality that matches it!

Volume without Baffle is an explosive, but there is no sound cracking than the one attached to Slip-on Silencer and Link pipe.
With Baffle it will hold me quite a lot of noise.
The warmth in the residential area is awful.

It is a feeling that said that making details is stone AKRAPOVIC.

To install it, you can attach it if you slightly shift the Oil cooler, but since there is a possibility that the Exhaust pipe is hit, I think that the work of removing the Oil cooler is OK.
Who wears it and Rear Sets (Me too) Fixed location will no longer fit, so some ingenuity is necessary.

If you do not set the fire setting, it will be worse because it is lower than NORMAL, so it is better to adjust the adjustment.
