we dyno'd our bike this weekend and our tuner overlayed my bike's stock results with my bike's full yosh results, AND another bikes full area P results with the same jetting (not sure what that is).

as you can see, the AreaP pipe barely edges out the yoshi, but he says that my bike still needs to be leaned out a little and that should put us dead even. we wanted to leave it a little rich since the first race of the year is traditionally pretty cold (been in the 30-40º range) which will lean out your fuel mixture.

final HP readings were after some calculating by my tuner:
Stock: 28.1 hp
Yoshi: 30.6 hp

dotted lines are torque.
solid lines are HP.
not sure what the dashed lines are.... maybe those are torque and i don't know what the dotted lines are??

red is stock.
blue is Yoshi.
green is Area P.

Thanks, Broom. That confirms what I've always thought... that no matter which exhaust (and I consider AP and Yoshi the better of all the options out there) one chooses for our bikes, the end result with jetting is in the area of 30HP. It all ends up a matter of preference.

Did he mention which model of AP they tested? Also, is the Yoshi a full exhaust? (I'm assuming it is)? Last question... why is it the AP readings stop at 12K?

i'm not sure why the areap stops at 12k.

I'm also not sure what areaP pipe he used. it says "Area P No Limits" on the chart. doubt that helps. the yosh is a full system.

Broom -

From the chart it looks like the stock machine didn't touch 25 hp, but you mentioned your tuner calculated it at 28.1; is there a correction factor that he's taking into account on that chart?

yeah, the 28.1 is a corrected number. not sure how that all works.

i guess i need to have my jt kit installed and taken to Advanced to see what they can do with it..... gp full system...... :D.... i thinkit will be close to what people have been posting

Side of the graph says: BHP, FtLbs, CO%. Usually the mix has its own graph on the bottom. Maybe thats what it is thou:confused20:

yeah, i just realized this afternoon thats the reading out of the exhaust. i think its an indicator as to what your fuel mixture is doing. our tuner said the goal is to keep it as close to 5 as possible.

Has anyone heard both the area P 12" and Yoshi system? Any idea which one is louder?

I like the AreaP because its quite a bit cheaper than the yoshi full system.

too bad the other bike didn't have a stock dyno run as well. as we all know, all bikes are not equal. he could have started out stock with more or less power than yours.

but at least your graph gives a pretty good basic idea. i think the yoshi looks better, but the ap sounds better (based only on video clips i have watched).

They are the two best exhausts out there currently. I have the Area-P Short full exhaust system on my bike and my buddy has the Yoshi full exhaust, I can tell you right now, Area-P short exhaust sounds ALOT better than the Yoshi, like it has balls, but thats just my opinion. Sitting idle at a stop light, it sounds so damn good, and then you take off, even better.

How about in a volume comparison?

Jack! Welcome to the forum - where in VA are you?
Do you think it would be possible for you to get a sound clip of the two bikes side-by-side as a comparison for us? That would be awesome!

All the mods that everybody has done to their bikes, how did it effect the gas milage of your bike.

nb

it goes down, but you end up looking like this... :D

With the dynojet and full Area P ...my mpg dropped an avg of 2 mpg.

BUT I'm probably riding it harder now that it has a little more get up and go.

I was thinking it might drop more, 2 is not bad.

I was surprised at how much the milage has gone down by adding the exhaust (and another washer to the needles) But Kelly has got it right, you have an ear to ear smile like this: :D

So...Which is faster and what are the top speeds?:thumbup:

Ha ha 2 mpg isn't bad at all. I guess I look at the bright side of it. I can drive my jeep and get 10mpg if I am lucky. Or I can ride my Ninja and anything over 10 is saving me money....Even if I do get 11 mpg on the ninja, which i think is impossible.

:)

Do the 2 extra horses really make the bike feel and act faster? I'd like to get a new exhaust, but don't know if i want to spend money on a full or a slip on. If the difference is that slight is the extra money worth it? Just trying to get input from your experience. Thanks!!

That would be awesome! I can't decide between the two. There are two many good and not so good videos of both.

i didn't get much time on the bike before we switched, but acceleration feels way smoother and better now. i think it feels a little faster. 10% gain in power is pretty good... even if it only equals 2 or 3 hp.
