Switching to Arata.. need some info.

Highly thinking about switching to the Full Arata Matte Black Exhaust. Going to be selling my Akra to Fantas but just want some info before i make the big dive.


Interested to hear about sound and looks. Is it loud, quiet, in between. Is the Arata REALLY worth it?

The Arata is a very nice pipe with a nice low rumble at idle. It's slightly quiter than my Leo if that gives you any reference. The FS weighs nothing as well. I put this same pipe on another '05RR last year. Sounded great!

one of the componets of a great exhaust is how well the sound freq gets true it, the smooth bends in the right places and silky wields make for better hp figures..

i'm hoping so there too becuz i wasn't super impressed with my dyno run with the setup i have now.

i actually produced a little less hp then an 04 with a slip on d&d exhaust and pIII and v stacks. i have a full akra race, pcIII, bmc race air filter, v-stacks

Where the two bikes dynoed on the same dyno in similar conditions? If not, then your comarison is kinda rubish...

i definitely felt a difference from stock right i put it on and even more when i got the pcIII in throttle smoothness & runs well with the map, i just wasn't expecting to make less thats all. anyone have any directions towards some dyno runs others have done?

I have a question for you.... i can't believe that with a FULL AKRA you produced less hp then q's D&D slip on!! something don't sound right with this to me.
like others have said, there are many factors to consider.
I could see if you had some lower end exhaust but to me , going from an Akra to and Arata can not be a huge difference. (the arata is friggin sweet though) I don't really think you will see a difference to be worth all the work in swapping out the exhaust again.

I would try and get a custom map for that akra first.


what are you gonna do if the Arata doesn't show you the results your looking for either??? Just gonna keep buying exhausts???

i agree with you, how can a D&D slip on (which i'm sorry to say is not as good a quality as the akra, sorry if you own one) make better gains that a akrapovic system, don't sound right,

ahhhh ok.........


I'm still having a hard time understanding why you aint getting the performance out of the Akra full system...

I'm not bashing you or nothing bro..... It's just that me, personally, If I dished out all that cake for a full Akra, , , It would have to have me "REALLY" disappointed in order for me to just re-sell it and buy another brand!

Like i said before I don't think you can go wrong with either one and if you have the money to play with....try it, iguess. Let us know what the Arata does

I bought my Arata used off of Ebay and have been very happy with it. Very noticeable difference vs. stock even before I added the PCIII. Especially noticed more power lower in the rev range and overall smoothness. As far as sound, not too loud, sounds nice EXCEPT at about 7000rpm the airbox screams! It's definitely not coming from the end of the exhaust and I can't find a leak anywhere. It just really resonates at that rpm. Makes me stay in lower gears to stay under 7000 or conversely higher to stay above it. Earplugs also help! Overall I am very glad I changed from stock. Plan to get it dynoed when things warm up.

Would the fact that i didn't install exhaust gaskets have anything to do with the low ball dyno run after the custom map?

whoa, wait up a sec. What did the bikes make stock? what did they gain from the mods? That is ALL that counts and all that can be compared. Two different bikes are just that, different bikes. You could both have Arata systems and custom mapping, doesn't mean they will make the same h.p. sheesh.

In saying that, to get the equivelent system in an Akra to the Arata, you're loking at Factory race systems, which you and I can't buy very easily and cost a tonne. To look at them, they are very similar to the Arata's. BUT will you gian 5h.p more from the Arata over the Akra? I'd say not, but you wuill feel the difference riding it, it will accelerate faster and drive harder off turns etc. It's not all just about dyno figures, but it will be better. Can you post the graphs, or has this been done already?

yah i can post the graph, gotta find it, might have it on my website just have to link it. Yah i never did the whole no mod dyno run and after mod dyno run, but i did do a dyno run on a different dyno before the custom map and v-stacks so I have that to compare to the recent custom mapping and dyno run.

yeah, but you can't say what you gained from stock to now, so it's not all that relevent, BUT I think you'd find that an average of many dyno's would inicate a stock figure from between 98-102 or so, h.p, and so, you've gained between 0-4 h.p. I wouldn't be happy with that, and I've seen 10-14h.p from the Arata mapped, vs stock, so it'll be interesting to see how you go. Let us know.

did you compare your bike before and after IE, stock vs aftermarket? If not you have no base reading. Did Spankie boy do a before and after as well? the only way to know which exhaust did better was to see what gains you made over the stock exhaust dyno. If you gained 8 and he gained 6 and you bike is still lower hp than his it is because he has a stronger motor.......you cannot compare bikes

wow i havent heard from birdman in a while. Im suprised he sprung up so much on this thread without the words "yoshi" and "great" :-P Good to hear from ya again birdie. For the akra vs arata... i think the matt arata is beautiful. If i didnt get my exhaust for such a good deal off egay, i would have gone with the matt arata although akra makes some good quality products as well.
