Limitations on vehicle height

Despite being Stainless Steel, it is lightweight at 4.4 kg and relatively inexpensive.
However, the Clearance of the Exhaust End and Swing Arm is at the Limit, so the ride height cannot be raised.
Please be careful if you are planning to change the Spec. for Circuit driving etc.
Also, please consider if it is acceptable for the exhaust air to hit the swing arm and cause it to become brown.
As for the power feeling, I didn't feel it much since the difference is only a few horsepower at 250Level.

I bought an early lot and there is a problem with grounding at the Right Bank.
The current lot seems to have been fixed, but there are no good images because of the later release of the Titaniumver and the above problems.
It is a pity, because the lightness and design are good. View detail

Certified products:？？？？？？

At NAPs Yukiura, we test rode the ZX-25R with SP Tadao Exhaust System, and our desire doubled.
I was patient, but I couldn't resist and bought it.
The installation was done quickly, but the Instruction Manual was easy to understand, and the removal of the OEM Product & SP Tadano Exhaust System installation was completed without any particular problems.
Gasket was prepared in advance, as it was better to replace it.

The replacement work of Exhaust System is only work of 8 Nut of Exhaust System and Bolt1pc. of Exhaust System exhaust pipe part.
Cowl related, too, when Right Side was removed, it was possible to work, and there was no particular obstacle.
Even if you work slowly, you can complete it in 2 hours.

I applied the engine and it worked fine, and that was it for the day of the exchange.
The next day, in the morning, I checked the tightness of Nut and Bolt and started running without any problem.

Since it was warmed up, it was a little noisy, and it started running.
I get to Route 134 and, well, I open the Axel in earnest and it's deafening to me and the sound is LARGE and LOUD!!!!
Is it like this? So I spent a few days to check it.

I don't like the loudness of the bike, and I'm thinking of selling the whole bike. What an idea ・・・・.
And in time, I was able to confirm on the Net that GoldSponge would change the noisy sound of the Exhaust System.
So, I decided to use Gold Dashi, which was not the method you recommended, but because of its shape, it seems that it won't slip out if I stuff it into the exhaust pipe.

When I told my wife about the Gold Dashi, she had a Small one and I packed it up as soon as possible.

Then, the sound quality which was grating became good, and I did not feel noisy though I think that the Largeness of the sound did not change.

Now, it runs good. The sound quality is good, too. Oh, good.

And the performance, especially the large change, I may not know. View detail

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. View detail

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. View detail
