there is also a micron, m4, and leo vince slip on:



I think big tuna has the leo vince or something

I think the micron is the best...it looks SO clean

Yes, I know, but are there any dyno information regarding thoes exhausts? or weight savings? lowest pricing?

If anyone could find out more info on the Micorn please post it up. I am considering buying this pipe. One thing about it that cocerns me is the baffle it has. I don't want to get a new pipe for it to sound like a stock one. Anyone actually heard one?

To: "integrate" Wow. Thanks dude. Either you got a great noggen on your shoulders, or you're a pipe maniac :wink: The pipes I'm most interested in at this point are the Yosh. rs-5 ti full system w/ duplex headers, Arata full ti sys, and (fading from my want list) Akrapovic Evo and Race sys.

I like the torque curve and looks of the rs-5, but the price is thrwarting. Arata looks nice, but that torque.

I've ridden dirt bikes for 6 yrs, street for 10, though i haven't owned one for the last 4. I never go on track, and my riding will be 80%, twistier than a cup of instant noodle soup, mountain roads. Which explains my desire for midrange.

Any suggestions? :lol:

whats wrong with the torque curve on the arata.
looks great to me.. look at how early the torque picks up.. all the way from 8000 rpm you have more than 40 ftlbs of torque... none of the other systems do that.

the yosh and the akrapovic dont seem to provide the same gains.

having ridden my bike with the arata on the bike felt very strong driving out of corners... and i loved how smooth the power felt.. lots of torque.. no real spikes in the torque and wide power band.

Vish. I was afraid i would step on toes, no offense intended to all of you. I downloaded the arata's dyno chart, but it was soo friggin blurry, i could hardly tell any of the writing. I wish i could ride one to try myself, but I'm in S. Korea and noone i know has bought a 600rr as of yet (fireblades are kings BYFAR around here).

I've been thinking it over and i may just go w/ the Arata anyhow since even if the Yosh did offer some decimal point of a torque advantage, it's not worth the $400. extra dollars, seeing it'll never see actual track duty, which is the only place such details would ever come through. and besides, the exhaust isn't all the mods I'll be doing. If i get pissed off at getting blown out of the water by all the liter bikes around here (which is all Koreans seem to desire), then i'll call over to Houston, maybe you know him, Terry Kizer, or Mr. Turbo. Bye bye power "deficiency". I like the look and size of the 600rr, it's the best looking production bike to date, and that's not just cause i'm a dedicated red rider.

One question for anyone w/ a full exhaust; when you remove the oem exhaust, then the heat shield goes along w/ it. How's the heat radiation? Slow days, fast days w/ tennis shoes on, sitting in traffic, etc.??? Ducati had a bad rep for that. :beer: :banban:

Bye the way, how long is that exhaust can? Maybe i should be asking Dan Kyle for this?? :bitchslap:

not stepping on any toes here.. but i looked at the charts and i like the torque curve on the arata much better.. wider and smoother.

none of the heat shields stay.. actullay the stock one has a metal shield on the exhaust and then a plastic one.. kind of an undertray... the metal one goes away with the stock... the plastic undertray stays.

i removed everything when i removed the stock plastics.. and i used a sheet of heat shield on my track plastics.. (it a little foil with a stick side)

talk to dan about the length etc.. or look at the pictures i put up.

I was going for the Yosh system, but now that I read about the Arata I'm starting to change my mind. I used to know what I wanted! :D

Look at the Yosh system, it gets its horsepower gains without fuel mapping. 7-8hp from the dyno charts. The Arata uses a custom map to achieve similar numbers.

So just think of how the Yosh will perform once a fuel map is made for it.
In my opinion the Yosh can only get better.

My $.02.

Probably not much more. Custom maps are mostly 'driveability' aids, they very rarely add that much peak power.

The difference with the Arata, is that it's ALL titanium, and it COMES WITH A CUSTOM MAP. I have one of Dan's maps on my RC (with Satos) and I can tell you I will now almost always buy from Dan because the work is already done.

Having a custom map made for the yosh probably won't yield more than 1 hp or so on top, and will cost between 200 and 300 dollars (more if they mess up your rear tire, which sometimes happens, good pressure or not), but it will probably feel much better.

Greetings,

Dyno charts are like fish stories.

In December we dyno-tested over 10 systems for the BMW R1100S..... Well tuned bike.....essentially did what the BMW factory did in 2000 to select a system for their BMW BoxerCup series. Their choice was JAMA Engineering who makes the LASER systems, they are engineered to produce performance, great looks and durability. We had the same results with our BMW testing in December.

Try a LASER combined with a PC and some incredable spark plugs that we will soon have available>>>>>If you want real power.<<<<<



We came to one conclusion......never believe MFG'ers MARKETING dyno statements.

The Yosh comes in All Titanium too from my understanding. Although the price of the Arata is a lot more reasonable. I think you can't go wrong with either can, as it looks like both Arata and Yosh have done some good R&D for a great bike.

Everyone just hold on a sec, Comparing the Arata Vs Yosh in this case is like comparing Apples to grapefruit.

  • 1. No data has been brought forth on the bike / dyno chart with the Arata system.
    The Yosh bike is a California bike which is down almost 10 HP to 49 state bikes. The Arata Chart looks like a 49 stater.

    2. The scales of the Yosh chart and the Arata chart are different so the curves are skewed.

    3. The type (octane) Fuel can make a few HP alone. What Octane did each bike have?

    4. Dyno machine types? This is a know problem.

    5. Elevation, Temp and humidity during during Dyno runs. They must be same or very close to be of any comparable value.

    6. An acurate Dyno comparo will only be good if both bike have a PC3 or an EMS.

Lastly from what I see on the Arata dyno chart, I am assuming the red lower line is the stock bike.
Now if the Arata dyno run in this chart is with a PC3 with custom map then I would say that the Yosh gains are better in most areas.
Also has a better torque gain over stock. Not comparing the Yosh to the Arata but the stock to Yosh Dyno runs.
We wont be able to get a true picture of the difference's in gain until the above items are on the same playing field with same bike types.

Just my own $.02 but my bike is over all much more responsive and easier to ride with the Yosh pipe.
Another thing is that yes I am biased because I have a yosh pipe and that my bike was the development bike for Yoshimura-RD of America.
Oh and I got the full system for free. Now If I had not had this oppertunity givin to me I too would be pondering which pipe I would buy.
I dont think that anyone could go wrong on almost any brand of pipe they are all so very good.
As for the remarks that they Yosh system is pricey I dont think that is all that accurate as the price
I see mentioned is the Yosh Retail price. I'm sure most people will be able to buy it from other vendors at a good discount.
After all is said and done, and If I had to actually pay good money for a exhaust sytem my money would go to Yosh. My main reasons are;

  • 1. Yosh thought out of the box and came up witha distict unique can
    (which BTW has better volume for can length than all other pipes
    on the market due to the cans trapizoidal shape, which is also why the can is straight).

    2. I saw how Yosh does their R&D and I toured the factory.

    3. MADE IN USA

    4. Quality in both workmanship and materials.

    5. Yosh still owes me an EMS system when it comes out.

1. bike is a CA model.. a 1000 miles on it.. fairly well broken in.
no.. the CA bkes are not down 10 hp on the 49 state.. all they have is a cat in the exhaust, o2 sensors which kick in at steady throttle and the evap crap.

the CA engine was stock in all respects.

2. scales are different.

3. pump gas.. 91-92 octane.

4. dynojet.. it doesnt make sense to compare charts from different dynos.. or compare different bikes to evaluate pipes.

5. dynos were done close to sea level.. sand city, CA near laguna.

the gain in peak torque does not look substantial on the arata.. but thats the best i have seen in all the exhausts.. including the yosh( only 2 ftlbs)

all we need to do is compare the torque curves and the improvements it made over stock.. the arata picks up 5 ftlbs of torque around 8000 rpm, only 2+ at peak and 5 ftlbs at even 13000 rpm.

thats what i meant when i refered to the flat torque curve.. i've ridden the bike before and after and i like the extra power.. even better i like how smooth it felt.. throttle response was much improved and smoother.

a lot of that comes down to the custom map dan made.. and i'm sure the yosh will develop a smoother curve with the EMS.

the arata compares well with other "factory spec" exhausts.. like the arrow on the same bike.

if the only critera is performance and weight the arata is a very good buy.

the yosh looks good too.. for both performance and looks.. and there are plenty of reasons to buy a yosh... all the reasons you listed for example.

And no, it's not correct to compare the Arata w/ Map to Yosh w/ Map because Yosh doesn't make a custom map available. At least they haven't for any non-suzuki bike that I have heard of. Plus the fact that mapping almost never adds any more (significant) top end.

I'm confused of what you mean about scaling, are you talking about sampling interval? Both have their gains stated in SAE corrected HP. This is why temp/altitude etc don't really matter all that much.

And I don't see yosh posting all of that info either.

There are only a couple of race fuels that will make power with no other tuning, throwing in 110 octane will do nothing and in fact likely decrease power. Fuels like nutec, VP, etc may make extra power by themselves.
