FYI , Akrapovic dyno numbers
Visited the Akrapovic web site again bored at work . Noticed that the HP gain on their Full Ti Evolution system is a whole 7.1HP for the 10R .
max. rear wheel power HP / rpm
STOCK FULL Ti Evolution
158.4 / 11880 165.5 / 11900
The Jardine , Muzzy's and others SLIP-ONS make roughly the same HP . Akrapovic even admits to a low and mid RPM power loss <5,000RPM under stock . And the price I heard was around $1200 to $1800 , OUCH !
I don't get it ????????????????? Why ???????????

Kinda thru me for a loop also, they quoted their slip-on as - "The power increase begins right at 3000 rpm, and the increase continues to grow right into the overrev range. At 11900 rpm it puts out 161.8 HP, and the max. increased power is 5.4 HP at 12200 rpm." And has their full system listed as - "The Kawasaki engine with an Akrapovic exhaust puts out an incredible 165.5 HP at 11900 rpm. The power increase over the stock curve is also incredible, a full 11.2 HP at 12500 rpm. Just to read it I would bet that whomever typed up the web pages messed up big time. They used the stock hp on both comparisions at 158.4 did the correct math on the slip on but the full system with an 11hp increase should have read 169.6 over stock. I'll let cha know if its a turd or not I got one coming in next week; just my personal choice their are alot of great systems on the market.

Theirs is a very honest representation of what you would get by just putting the pipe on. Some of the others show you the gains with remapping, but its buried in the fine print. I know for 2 of the ones indicated that was the case.
Jardine seems to be one of the folks that does honest representations as well, and if you check you will see they do not claim nearly those gains.
The Akra will produce more with remap.
There seems to be a great deal of misunderstanding around dyno charts in general, whether that be different dynos or disparate amounts of tuning.

Must be Erich, I am still up in the wind about the different numbers and graphs they listed but if I can just bolt it on without a pc3 and it feel streetable I will be happy. I would like to save the pc3 setup when filters and cams are available on the market. Their slip-on looks nice but I wanted the same uniform pipping. (I'm just anal).

I spoke to Arata in Huntington Beach and the guy said that they won't be in the states for at least a couple more weeks :-( but the numbers going around the company say 11HP without remapping.

It's not like I "need" 11 more horses, heck this bike prolly pulls 30 or so more than my modded RC51 did, but it will be nice to say the least. If the Arata only equalled what the Akra does is fine with me, it's cheaper and it looks better to boot.

Erich , you are right on one thing . Jardine does not claim 7HP . They almost deliver it . And also they deliver it for a hell of a lot less coin . Plus they are AMERICAN MADE .

If we were to ride the "Made in America" wave then this would be a Buell board . . . lol

Do you really think all the Buell parts are made in the USA? Of course not. But then again, don't we have some Kawasaki's made in Nebraska? Or Honda's made in Marysville? Who knows...
I can tell you, as DKET states, Jardine's are made right here in Corona, CA USA! Not that that makes them any better than any of the others. But it is something we are very proud of.

I think they said that maximum gain over stock is 11.x horse power, which is true. They just fail to mention that this gain occurs in the middle of the power band ......

Ya know I can see that in the graph, but I keep trying to put too much thought into it. I guess I would rather have it in the middle than all on top. Thanks for pointing out what should have been plain and simple.

Their claim of 11HP is misleading . They are claiming 11HP but neither pipe is at their peak . Peak stock compared to peak Akrapovic Ti Evolution 1 is 7.1HP . Those are their figures .

Akra makes very high quality systems, they tend to produce 6-8 more max hp with bigger gains at redline where the restriction of the stock system does the most damage. They tell you where the increases are and also provide a graph. How is that misleading?

DKET & bovine are both right. The problem here is that most sites give you peak numbers where Akra gives you numbers across the board. The only problem is that if you only take a quick glance at the Akra site it looks like there saying 11hp at peak. Is it written like this to mislead people so they see more pipes? Only they know, but I have my opinion.

speaking of Arata.... have ya'll heard them? I met a guy at the local sportbike hangout last night with a 929RR with an Arata f/s. Sounds good at idle, then he revs it...... nearly blew my ear drums out! I mean, I've heard people do the same with D&D, Yoshi, and various other pipes and they were loud, but not like this.... I hope it's not that loud when you're riding it, cause you'd go deaf
