2/5

It's a shame, because Parenthesis looks great.

[How is it used?

I switched my car to a Z900RS and the NORMAL sound was not bad, but
Purchased because the sound quality was a little different from my taste and I wanted to change the appearance and reduce the weight.

The following imprements were installed on a previous Z900 (unmarked)
Full titanium exhaust & SC1-RSilencer by SC-PROJECT
This is a very dry comparison with

Was the one you received as per Image?

Material:I found it surprisingly heavy for this Size in Titanium.
The slanted area on the opposite side of the exit has a rough surface like sharkskin.

Was the installation difficult?

When installing the inner baffle, use a ring to hold it down so that it does not wobble inside.
The system allows the user to enter the parts, but there are many similar parts, so it was difficult to know which parts to use.
I wish they would number the bags containing the Parts.

Silencer band is included, but you need to prepare your own bracket and bolts for fixing.
You need to be creative and inventive yourself.
I installed it in combination with K-fac's CLRExhaust pipe,
The bracket is Nankai Parts' Universal Bracket Length 225mmOffset 75mm (Part No. MSTL-225FR-75),
The silencer was fastened to the OEMLoading Hook by using the OEMSilencer Fixing Bolt.
Spring is the one that came with the CLRExhaust pipe.

However, the Silencer band is a little small in diameter and deformed when used as it is.
The bracket is then connected to the OHLINS Preload Adjuster.
Spacer of 3mm was put in because of interference.

How was your experience with it?

In combination with K-fac CLRExhaust pipe, even with inner baffle in place.
Considerable blast from Idling.
It might be more annoying than the SC-PROJECTFull Exhaust System without Baffle that was installed on my previous Z900 with the same Straight structure.

The Z900 series has a high ColdStart Idling.
Idling in a residential area is a Level that is sure to be Objection from neighbors.
Baffles can be attached to the exits as well,
It sounds like a whistle, like a Large Dump car, and I can't bring myself to use it.

The sound quality is rough and muddy from Idling with CLRExhaust pipe + Inner baffle.
The sound does not become a clear high-pitched or pleasant sound as it is turned, and it remains a harsh, dusky sound until the very end.
The trend may be similar to the OEM sound.

It seems that the inner baffle is causing a lot of exhaust resistance.
I don't feel that the low speed Torque is extremely gone and AfterFirea is not at all.
I feel that the performance has been downgraded quite clearly because it feels like it is jammed on top despite the bombast.

I tried running the next day WITHOUT Baffle's full Straight and it was so loud that I could say it was heinous.
Level, which is no different from the straight pipe of a family car.
The sound quality and running are better than with Baffle, but at any rate, it is too noisy.
It is highly likely that we will abandon the use of the system, although we need to consider whether we should compromise on driving and sound by emphasizing style.

Very disappointed because I like the look of Large.
Link pipe and Quantity as Slip-on Silencer for Z900RS OEM exhaust pipe:There are some that are sold Set.
It might work there.

[Included Parts:were they on?

・Instruction Manual
Silencer Band (possibly Material):(Stainless Steel)
Adapter for mounting on 54mm exhaust pipe, Spacer, etc.
1 pc. each of exit and inner baffle for installation.
K-fac Emblem
(Spring not included)

[Was there anything that disappointed you?

I was expecting the sound quality to be clear and pleasant like the previous SC-PROJECT car.
With Baffle, it was like a very loud OEM that I didn't like.
The sales pitch was that the volume could be adjusted by using a combination of inner and exit baffles.
The volume of the Inner is not as low as expected, and the sound quality is poor.
Exhaust resistance is too Large and performance is down from NORMAL to Large.

2/5

Disappointed with the roughness of the finish.

[How is it used?

I switched my car to a Z900RS and the NORMAL sound was not bad, but
Purchased because the sound quality was a little different from my taste and I wanted to change the appearance and reduce the weight.

The following impressions are in comparison with the SC-PROJECT full titanium exhaust that was installed on the previous Z900 (unmarked).
So it is very dry.

Was the one you received as per Image?

The finish was worse than expected.
All of the pipes have scratches from the manufacturing process, and all of the exhaust pipes have weld marks.
It looks as if it is not a Pipe, but a plate material that has been rounded and welded.
The surface of the bending part is decorated with wrinkles.
Roughened surface like sharkskin can be seen throughout the entire surface (especially on Tail Pipe). (Tail Pipe is especially bad.)
Material:I also felt it was surprisingly heavy for Titanium.

The SC-PROJECT product was surprisingly light, with excellent finish and precision.
I assume the lightness is due to the use of thinner-walled Pipe than this product.
Naturally, the thinner the material, the higher the technology required for bending and welding.

Was the installation difficult?

The joint with the Tail Pipe also went in without any problem when combined with the same K-fac Bullet Silencer.
Aluminum's split flange seems easy to install, but in reality, it is not easy to install on the Stud.
It is difficult to do because of the "Rose" effect.
The installation of the assembly was easy, with no particular misalignment.
Clearance with the lower part of the Engine is quite low, making it difficult to set an extreme Pushing Up Style.
The Bracket that fixes the Wiring of the OEM's Lambda sensor was removed because it hit the assembly area.
The Lambda sensor mounting part is for the Z900RS, but for some reason, the position is on the opposite (back) side of the OEM.
It looks hard to do when removing it because it is about 10 cm away.

Since there are only two fixation points, one at the exhaust flange and the other at the silencer, it can be used for a long period of time.
Durability is a little uncertain.

How was your experience with it?

The thick exhaust pipe that looks like a hand bent, and the silencer angle of the pusher is also good for Parenthesis.
Material also gets a burnt color if it runs.:The good thing about TitaniumExhaust pipe.
The sound may depend on the Silencer combined, but since the catalyst and SaPig equalizer are eliminated, the sound is basically bombastic.
The sound quality is muddy from the Idling, with a rough, dusky sound rather than a clear, pleasant sound.
Exhaust pipes are just bundled together and not etc. length, which may cause turbidity due to exhaust interference, etc.
Frankly, I do not prefer it compared to the pleasant sound of SC-PROJECT.

Combined with Bullet Silencer but with Inner baffle
It seems that the exhaust resistance is quite low and I don't feel that the low speed Torque is extremely low, nor is the AfterFire at all.
It feels like the performance is down because it feels like it is stuck on top of the bomb.
I would like to eventually try it withwithout Baffle and other Silencer to see how the volume, sound quality, and performance changes.

If you think that you can get a Titanium Full Exhaust System at a relatively low price if you choose a cheap Silencer, you can get a Titanium Full Exhaust System at a relatively low price.
I would recommend it if you think it's cosmetic but don't care about the rest as long as it looks good.

[Included Parts:were they on?

Instruction Manual、Material:Includes AluminumFlange and Spring. (Also available for SilencerSpring)

[Was there anything that disappointed you?

As already mentioned, the roughness of the finish, weight, and sound quality are all disappointing.
Perhaps it was made by an apprentice? The finish makes you think
I must say that it is a bit disappointing to ship this Level in a product that costs more than 100,000.

According to the Instruction Manual, it is not returnable once the Vinyl containing the respective Parts is broken.
It is better to Check well before opening the package.

What does it mean that the initial four-month wait was suddenly delivered the following month?
Would it be too much to suspect that a B-grade shipment was made...

It was expensive to prevent Rust.

I have attached a Stand Hook even though I do not have a Maintenance Stand. The purpose is to prevent bolt hole rust.

I ordered at Tension at night even though I'm not particular about K-FACTORY, and when I reconsidered, it had already shipped and I was done with it.

If you want to prevent Rust, you can use a cheap one.

As mentioned above, I don't have a maintenance stand, so I don't know how I feel about it, and I don't have any feelings for K-FACTORY as dress-up parts. View detail

The O-ring doesn't fit.

As other posters have pointed out, there is no space for the O-ring to fit. I'm disappointed with this, though I'm sure the purchaser is supposed to do something about it. View detail

Looks good, effect unknown, medium difficulty to install

I installed it on my CB1300 SP.

For some reason the CB1300SP doesn't have a Fork Guard. ('; Ω; `)

I've installed KIJIMA's 1,000's in other cars, but KIJIMA's were fixed with Tie Band, so it was quite easy.

This is Bolt On.

The screw is a Torx screw to prevent theft.

It comes with the L-shaped Torx wrench you need to install it, but you will need a separate tool to fix the Nut.

The difficulty of installation is higher than others.

In brief, Power pushes Nut into Fixed Band, and Power spreads Fixed Band to cover Outer tube.

Then tighten the Bolt with Power.

We use Power all the time.

When installing, it is necessary to work carefully so as not to damage the Outer tube.

I like the way it looks installed, just like Image.

However, the cosmetic is bad, so if you just want Fork Guard, KIJIMA is enough.

So if you are looking for Titaniumium color, this is the one for you.

Material:If you want to use Carbon Style (Carbon Seat must be attached), you can use KIJIMA. View detail
