Nice video. It looks like an incredible product.
We have been in touch with RexXer through our copyright attourney, we don't like the fact that they have been selling our Cruise Control without permission.

Oh boy, that's a shame. Looking forward to your final results.

Sorta settles it then huh fellas? Thanks for all your work here, Wayne. Akra should pay you royalties.
I have been reading this thread with quite some interest and I have concluded that Akra's full system seems to be better than Termi's full system. The data provided by our fellow posters proves this point.
It makes me wonder though, can any one explain where this improvement is coming from? Are there are any geometrical changes that is influencing this change?
Dont you guys think Termignoni will be embarassed after seeing that change when they are Ducati's defecto performance exhaust provider?
I just bought a Termi full system 2.5K GBP, there is an Akra full system for sale here in the UK for 3K GBP, so tempted to get that one instead and return the Termis.

Return the termis. The akra is on the SL. That should say enough in terms of what ducati will be putting on future bikes

Hey now!!!! That's only a 5k package for you. And it comes with a gold rim around the termignoni sticker.

I'm seriously thinking of pulling the trigger with the Akras. These in conjunction with a Rexxer flash to the stock ECU should be all you need. MotoMummy still have them at a good price so maybe once the expense of Xmas is out the way, they will be next on the Project 1199SPS shopping list!

One thing that everyone is overlooking is tuning.
What I mean is; These before-and-after or with-or-without the latest system (in this case the Akropovic) dyno runs are usually with no tuning on the 'before' and tuning on the 'after' run.
Who is going to pay to have the bike tuned twice? Most of the time not the customer and not the tuner. He's got other paying jobs to do.
This commentary isn't about the Akro, those guys flat do their homework and their stuff is as good as it gets from a performance standpoint and that's all that matters to me. If it looks good, fine, if it's ugly but makes power, catch me and tell me that it sucks. (JMO)
The example is the Tri-colore that I did for Ray Kang. The baseline with the Tuneboy tune was way too rich everywhere, but particularly bad at 9600. (I don't have my dyno runs handy so excuse any inaccuracies.)
Which is why it only made a peak power of 165hp for a baseline.
Rather than tune it the old fashioned way (reading, modifying, and writing the ECU), I got the Tuneboy Trim to communicate and tuned it.
The result is in the Technical section. What you see is before-and-after tuning.
If you do a before and after a pipe change and don't do any tuning, the result may or may not represent the two system, but most likely will have nothing more than pure luck to get any gains.
The calibrations for a lot of Ducatis are way too rich at WOT so if your new pipe increases the torque, the calibration will be less way too rich.
Keep in mind that if the mixture is 20% too rich in places the new pipe will have to make 20% more torque in those places to make the fueling correct.
In the latest dyno charts, it appears that the Akro makes 68% more torque at 4900 RPM. Well, it (probably) doesn't, the dip is (probably) due to rich misfire on the baseline run and tuned on the final.
I can't be positive without seeing the AFR chart. And even that can indicate lean in the middle of that dip due to misfire. It can be in the middle of a very rich trend, then show a spikey 18:1 right at the dip.
If the new pipe does make more torque in that dip, it may not misfire, therefore showing big increases, but tuning will make it as good as it can get.
You don't need to spend $5000 to get benefits from tuning, and that makes tuning the value part of the equation.

Is the "Troy Babich" dyno graph above showing a TuneBoy flash,RexXer flash or PCV etc.?
The post does not say what was used to tune that bike.
Topolino
Can I ask why you would chose the RexXer flash as the tuning method.
Do you have the software to make changes to the RexXer flash, as I understand it you cannot adjust anything with the RexXer unless you have the RexXer pro and the software, this would cost almost as much as the exhaust system.

These three screen shots show the air fuel ratio of the Panigale tuned using the TuneBoy software.
The first is 47% throttle, then 62% and last is the 100% throttle trace.
The two lines on each graph show the front and rear A/F ratio.

Thanks for asking that very important question Wayne.
Thanks for asking that very important question Wayne.
someone commented that the graph still has a dip in the torque.
The following screen shot shows a tuned 1198S vs the 1199 Panigale with Akrapovic.
The 1198 had the full Termi exhaust and was also tuned on the TuneBoy dyno in Sydney.
The axis on the bottom of the screen is road speed, both bikes in fourth gear.
Red is the 1198, blue is the 1199.
You can see that the Termi 1198 has more of a dip in torque(110kph to 115kph) than the Akra 1199(105kph to 125kph)
In the same gear the Panigale with Akrapovic has more HP than the 1198 Full Termi at all road speeds, it also has more RPM but that is what a gearbox is for.
I hope I have answered any questions the forum members have about the Akrapovic system, I have no connection with Akrapovic but I am the programmer who writes the PC and ECU code for the TuneBoy product.

One last graph and I am sure this is a question in many minds.
This graph shows the following bikes on the TuneBoy dyno.
Red is the 1199 Akrapovic.
Blue is a standard BMW S1000RR
Green is a 2013 ZX10R, standard exhaust but fully tuned.
This along with the "Troy Babich" graph showing 191 DynoJet HP should clear any questions about DynoJet numbers v DynoDynamics numbers.
