GT-One v5.1 is no longer available at this moment. Apparently the financial issues within GT-ROM and their manufactures are still in dispute and all of us have to wait indefinitely. My business partner in Japan notified me that we should try a different approach and ask me for my input, and we decided to offer some thing a little different. Think of it as an alternative.

Couple of Problems are currently facing:

1). The exchange rate is our biggest enemy; as of today 10/26/2008, it is $1USD:92 Yen. When the GB of the v5.1 was issued three months ago, it was $1.00USD:107 Yen. We just lost 15% in USD value, hence a 15% increase in cost for any one who still desires a v5.1. For example, the original price of $2900 will be $3260 today…

#2: We weren’t able to get the best deal from the factory because GT-ROM is the authorized vender. We were able to buy from the factory because GT-ROM wasn't meeting their quota and our purchase was for export only.


The Story:
Being a brass (trumpet) player, I know when bending the pipes, smoother bends can minimize bottle neck of the air flow; therefore, when applying the same approach to an exhaust system, the sound will be more natural and "may" free up more HP, some thing we all desire in an aftermarket exhaust. When examining an exhaust system, immediately came to my mind was that “only if 5.1 have less weld spots and smoother bends. During the last three months, the factory in Japan offered to create our own muffler, I like the idea because I know the quality of workmanship/material of JDM goods is hard to beat. My friend suggest the possibility of having the same factories to produce our own exhaust, and I figure why not? I like the idea!!!

But anyway, here it is:

This is the prototype NA2/LEV Dual Tip exhaust. If you compare to our competing unit, you will find less weld spots with smoother bend, more organic like piping.

More photo and sound clip coming soon.

Pricing including shipping and all international funds transfer/bank fees:
Pricing according to today’s (10/27/2008) exchange rate of 92 yen to $1 USD:

$2,650.00 for dual tips
$2,900.00 for single tip


Keep in mind that the price will fluxuate due to exchange rate. Hypothetically speaking: If the we're sitting at 100Yen:$1:00USD, and amount of orders per transaction. (There is a cost of $50 per international money transfer regardless the amount, and there is also a 5,000 yen service charge to receive the money in Japan)
You will see a approximate price of:
$2350/$2400 for Dual Tips
$2650/$2700 for Single Tip.:wink:


Paypal add 3.25%
AMEX Add 3%
VISA/MC add 2.25%
Personal Check and MO OK.




Again
Keep in mind that the price will fluctuate base on the current volatile exchange rate, I'll figure out the true cost during the time of transaction.

So, this exhaust is made by the same factory that makes the 5.1 but changed a few things so it's not a complete copy?

I'm not trying to knock the idea. I'm just wondering why someone would pay about the same for this exhaust that the 5.1 would cost.

Don't want to hi-jack your thread but am curious why you changed the original post? You stated in the first story that the factory offered to modify the v5.1 to make it their own. You would then buy the rights to this modified v5.1 exhaust.

Claiming that it is your design is a stretch.

Why change the story?
 
Re: Bel Canto - Soprano Exhaust system by NISHIMURA

looks like it will hurt airflow with all those bends, but im sure it sounds nice
 
Re: Bel Canto - Soprano Exhaust system by NISHIMURA

Its a product on offer. Get it if you like it.
Must all product be the 'new and latest'? For me NSX aftermarket is small to get too fussy. IMO.
 
Re: Bel Canto - Soprano Exhaust system by NISHIMURA

I'm interested...but I'm curious how something like that would perform with a CTSC...and how loud is it?
 
Re: Bel Canto - Soprano Exhaust system by NISHIMURA

You can only bend the piping so many ways to get that high pitch F1 sound.

This is what we are competing with:
From ARMS ENGINEERING:

348,000 Yen
GT-ROM 5.1
47.jpg

248,000 Yen
Route KS
f40m.jpg

270,900 Yen

And few other manufactures. They all have similar piping to get that high pitch sound.

If you're interested, please PM me.

By doing this post, you already have:rolleyes: I decided to make the initial post shorter. If you recall, the post was twice the length. At the moment, there is no point of explaining into detail because the way business is conducted in Japan. I also want to avoid translation problem since my Japanese is half ass and his English is also half ass.

Is the proto type for sale?

Yes, it will be $2500 shipped. It is really the final Prototype/First Production type. Don't forget, it is NA2/LEV (2000 - 2005)

So, this exhaust is made by the same factory that makes the 5.1 but changed a few things so it's not a complete copy?

I'm not trying to knock the idea. I'm just wondering why someone would pay about the same for this exhaust that the 5.1 would cost.

Beautiful idea. Get the v5.1 on my other thread:wink: Actually to answer your question, all you have to do is read the original post again.

Also

Some NSX vender in Japan may not be around in the future, with them, their products. v5x may go with it.

Vance, I brought this up a few months ago in your thread about doing a knockoff/clone exhaust. Do you seriously mean that there are no welders (people), welders (machine), and stainless/Ti sheet metal & tubing in this country???

This would get you around customs, shipping, & the exchange rate. Common sense would seem to dictate: MAKE THEM HERE!!! There are more than enough race shops & fabricators around.
 
keepin' it real, y0!

I really don't want to do that. I have a great relationship with one of the most active NSX-R parts supplier in Japan and this WILL damage the relationship. We invested some money in this exhaust so BOTH of us can make money. The last GB deal, I was charging $150 brokerage fee per exhaust, after order #3, I actually lost the fees by holding the same price when the Yen got more expensive (I was instructed to wire the money after each exhaust was complete, and the yen kept on getting more expensive as time goes by). As indicated, I rather have parts made in Japan knowing that I'm getting the highest quality steel and workmanship without having to worry about six months later with complaints of problems.

We made the connecting pipes slight larger to ease the air flow and fight the slight raspy sound at lower RPM when competing to similar products. See photo for the change.

If you want to be our first, I can save you few bucks for being the first. We have one coming off the factory this Friday for LEV NA2.

Let me know.

Re: Bel Canto - Soprano Exhaust system by NISHIMURA

Are these being made by Nishimura or Kuroda?

Since its copied anyway why not make it in the states as you can save on customs, no languauge barier, not up an down yen, much much cheaper, better quality and it can be tested for fitment before someone spend over $2500 just to be your test mule.
Oh thats right than you can't charge these crazy prices for just an exhaust.
 
Re: Bel Canto - Soprano Exhaust system by NISHIMURA

I don't mean to be negative, but changes in pipe size actually cause LESS airflow than more. I was discussing this with a friend who is an MIT professor. He said if you took a straight pipe that was 2.5" in diameter and then cut sections out and increased the diameter, you would cause bottlenecking at every joint. Furthermore he said it will cause changes in velocity of the exhaust, and those changes further restrict flow.

I don't know... sounded logical to me and he got into the math that was beyond me at that point.

Maybe this does apply to this exhaust maybe not. I am just raising a question is all. Did you guys check into this Vance? The bends look very good.

Dave, I belief you miss read my post. See the picture on post #14. We used larger piping on just one area of the exhaust, not the entire thing. The reason for making that one section with slightly larger piping was to address two problems I found:

1. One was the "dadadadadadada" sound under low RPM. With slightly larger bore bypass pipe, the accent will not be as strong.

2. second is to relief some back pressure. Many 5.1 owners have CTSC, this should help free up few more ponies, along with smoother bending of the pipes and less weld spots - Which generates less turbulence. This will also help generate a fuller sound. I'm using trumpet as analogy. The amount of piping generate the "key" it's in, and slight larger bore will give you a fuller sound. By keeping the piping length the same, both will have same pitch.

Hopefully that answers your questions. The bottom line is, our competitor is NOT offering your exhaust for export, and they have made it difficult from us to bring them States side. That particular vender is putting bitter taste in my mouth time after time even though the owner is the one who caused the problem by accumulating massive debt to the factory.

Vance, is that exhaust in your possession. Who's the lucky guina pig?

No, I'm going to keep my v2.0 because that's the sound I like (we're working on some thing similar to v.2 right now, but the new project will depend on this one). The final prototype/first production type fits fine, just like any other exhaust from Japan. We have not try it on a NA2 because there are very few NA2 in Japan, but the NA1 version had perfect fitment. We don't anticipate any problems for NA2 because the pipe mapping is around for a very long time. The bottom line is, it is made by a factory that does nothing but high end exhaust system, including exhaust for NSX, GTR, and some Italian brands.

I'm not trying to knock the idea. I'm just wondering why someone would pay about the same for this exhaust that the 5.1 would cost.

The Price difference is huge. In today's exchange rate, you are talking about about $600 plus difference. Also judging from the current situation, GT-ROM is not selling internationally.

Vance, all the big pipes are going into a smaller diameter pipe to mate to the rest of the exhaust. At that section where it gets smaller in diameter, I would think you are creating backpressure and changing the velocity of the exhaust, no? Does what I am saying not make sense?

See the black circles.

When the pipe is enlarged, you loose back pressure. In this case, when compare to what you have, our exhaust will have less low torque, and should cough up few ponies by read line. When you look at v5.0, the exhaust is more restrictive from two reasons, the angle of the bend and two small bypass pipes. That will cause restriction, which will result in few less HP to be freed.
 
Vance I was under the impression that this exhaust was made for a UK company and that the piping was changed due to legal reasons???

I know of this as I asked said company about GT-Roms and they were working with Mr.Taita to get this exhaust made up. ( PS I only wanted one for me )

There will be 20 ready by 11/20 and the prices are very good.

Cheers,

AR
