The WSBK bikes had those features way before we got them in the production panigales, but yes I'm sure their addition and improvements help.

The exhaust on the WSBK Panigale is one of the most complex systems I've seen. Varying diameters, resonance chambers offset lengths, flapper valves and a 2>1>2 design! Wow! Change the cam specs, cam timing and or the intake/throttle side size and length, even just a little, and you would need to tweek the exhaust side at the same time. You would probably need a VERY capable computer along with a specific engineering SW program to calculate all the data.

The whole purpose of such an intricate design is to not to just increase the power but to spread it over in a specific rpm range range. For WSBK it is likely to be in the top third of usable RPM's. It wouldn't surprise me if Ducati has a couple different WSBK exhausts designs. One used for the tight lower speed tracks where a broader torque range is needed and another for the faster more open courses where you need more top end power.

Putting on a leftover WSBK or designing a true copy of the exhaust on stock Panigale probably won't give you much USABLE increase in power. In fact, it would most likely hurt you in the end. Remember, it is a racing package or system....you need to modify the whole engine to near WSBK specs in order to get the most out of the exhaust. If you don't, you will create flat spots and power spikes making it harder to put the power down to the track in a predicable, linear way. BTW - You don't even want to think of how all thus might screw up your traction control either...!

Think about it... There is a reason why Moto GP teams show up a couple weeks before a race to tune for a specific track. It's not just about the tires. The electronics traction control and engine tune along with suspension and brakes are all set up for that track and more important to the super human alien skills and style of the professional rider.

To be honest. I would look at what is used on the Panigale for Superstock class racing as a basis for your exhaust design. They aren't allowed many internal engines mods so their designs are based to making the most of our stock design. Since I'm not independently wealthy any system I would use would have to be somewhat simple, affordable and easy to repair or replace AND make better power too.

IMO - That makes for a very full plate...

..the real deal "black opp" wsbk version wouldn't be any good to "normal citizenry" - so just buy and SL....there is a "consumer version" that comes in a box with the bike

I was having a chat to Troy Bayliss'c team mechanic a couple weeks ago about their current team bikes. They were still using the under akra's. Asked weather they were going to under seat exhaust like WSBK, they didnt see the need to at this stage as the cost (even with their discount) wasnt worth the gains especially this late in our race season and with a new model due.

Funny thing is that if you look at a cost of a Panigale RS, then look at the individual pricing of parts, the RS bike looks to be a pretty good deal!

Strange you have suggested looking at the Superstock class, as Mike Jones races for Aruba Ducati, later in the year if all goes to plan we will be teaming on my bike for a 2 hour enduro. Idea for the race format is to get fast guys teaming with local not so fast guys(like me), and make a race of it. He is a young guy on the up , already wild carded for Avintia at GPs last year. I would expect to see him on a Ducati for WSBK in the future
