A real comparison on a 959
A perfect scenario would be a prominent bike shop installing and dyno-ing each of the 3 kits mentioned on the same motorcycle. That will give us a clear picture of what to expect for each exhaust.
Of course with regards to performance on the 959.

are you going to install your stock exhaust to have a Baseline to compare the new Termi's with?
if not, how will you know if/how much better it performs over the stock?

so if you thread search dyno run stock 959 there is base line runs ( yes for EU version ) they're a little more restrictive then our's in the states but i can only image not by much , plus that video with the EU bike with akra exhaust that was it, now when i dyno it wont just be with with exhaust but also air filter and tuner then dyno and map so im sure my results will have a considerable increase in HP & TQ over EU bike ....

that's exactly what I'm NOT looking for... my bike is bone stock and I'm wondering how much performance difference adding one of these exhausts will do

c'mon... u can't possibly think i'm asking about a slip-on comparison...

Come on bud , full systems on our bikes are point less waste of money if you knew this bike or did your research you would know that , your best gain with exhaust would come just from a slip on
( the why ) again due to the cats being inside the stock exhaust tip or canisters restrict air flow now if you throw in a slip on that deletes the cats and removes the servo motor and that let it breath better in terms more gain ...

Fully agree, especially with the 60mm primaries. The motor does not need bigger headers, so unless you just want to remove weight or do 75mm ones and move your power band up even more, a slip on is your best bang for the buck by far.

The slip-on performance numbers availability are slim to none. The Akrapovic performance specification gains for the now defunct Panigale 899 is only published for the full EVO Akra titanium system and not for the slip-on. And even then, the maximum gains are about 4.7HP in the 5900rpm range with very little advantage at the top end. Moreover, their Akra slip-on spec advantages listed for the 899 are those from the 1199 which is disturbing. (see the footnote on the screen-shot attached) You would think they would have tried the slip-on first before the full Akra? That's disturbing.

wow - do you think that's a typo? like the web dev just copied and pasted without updating the text?

That's not a typo as the gains shown are higher for the slip-on than the Full titanium system. Those numbers are from the 1199 not the 899. Akra would certainly show the 899 slip-on numbers if there were a marketable performance increase. The fact that they are not showing those figures really bother me.

At the risk of being flamed for writing this rant, IMHO, the whole after-market exhaust industry is simply feeding on ego and gullibility. There's no question in my mind that the motorcycle manufacturer's engineering talent and R&D budgets are leaps and bounds beyond what is available at these after-market firms. The reason for Ducati and other motorcycle manufacturers not marketing racing exhausts "in-house" is to detach themselves from the regulatory liabilities. There's plenty of evidence showing that coring the stock cans combined with un-clogging the air intake and re-flashing the ECU to maximize the fuel mixture's efficiency could yield very similar results at a fraction of the price.
I have no problem with buying these after-market parts on cosmetic grounds or weight reduction reasons if that's what turns your crank. However, when it comes to increased performance, we should hold these firms accountable for backing their claims with proper statistical data. As it stands, the documentation on both Ducati's and Akrapovic's website is pathetic to non-existent as seen here attached.

I agree that the performance gains with these after market systems are minimal. The latest generation of super bikes on the market are leaps and bounds over what was available even 5 years ago. For me, the addition of a slip-on system on a 959 would be purely for the DB gain as I would imagine the bike has more than enough performance as is. I say this based on what I know from the current / previous Duc's I own / owned. I take delivery of my 959 this Friday so I will soon learn the skinny on this bike first hand.

Congrats. Mine is all paid for, got my plates but pushing back the delivery date on account of the **** snow. We got a few inches last night. Weirdest April I've seen in years. Looking forward to hearing those DB's as well.
