Spent most of today racking my brain after failing to fit a Termignoni slip-on belly system to my 2016 959. D155102CPT - D155Y2

Instructions were poorly translated Itanglish and pics were for a 1299. Waste of time.

I'm struggling to get the system to fit between the front bracket and the original exhaust pipe flange face. I fitted the dedicated y-piece converter to the two silencers and made it up from the rear using the flange clamp. The front bracket then doesn't hinge far enough forward to align the two securing screws at the front.

I then fitted it from the front bracket and the y-piece hits the rear tyre. It's about 35mm out.

Just seems like the whole assembly is too long or the front bracket is not correct for the Bike. It hits against the exhaust valve motor housing and stops any further movement required to locate the holes.

There's two fixed points; the exhaust pipe flange face and the front bracket support holes.

I know this won't make sense without pics and I'm sure this system will have been fitted before.

Anyone got personal experience of fitting these items? Problems/thoughts/ideas appreciated?

I'm thinking it's the y-piece not properly located or the bracket should have some kind of recessed mid section to profile around the exhaust valve housing.

I can make an adapter plate to accommodate the gap but reckon an exhaust system of this price should be easy. Also it might be an issue when I fit the modified lower fairings if not correctly aligned.

Cheers
Bill

Yes - the exhaust valve assembly should be removed.

Thanks. Whipped the motor valve out so plenty of room to finish the job. The plastic quick connect blank doesn’t fit the wiring tail but other than that the silencers are on. Not entirely sure why they are called silencers. These are loud!

I realize that not every member of this forum is a fan of the front exit Termignoni, however when I heard it on a 1299 a while back, I remember really wishing I had it installed on my bike. If I didn't already have the rear exit and RACE map, I would be hard pressed to decide between the Akrapovic and these. The stats are impressive and indicate that removing the extra bend in the headers could provide a benefit over the previous design that I have. The imposing appearance adds to the package.

I'm sure it sounds good. Not having a Cat however has a lot to do with it in addition to the carbon which produces a distinctive sound of its own.
However, without opening-it up, we really don't know if it's straight or looks like the tail of the dragon.
Pipe diameter and length affect torque in significant ways. Larger pipes pushes peak torque further up the RPM range. Smaller diameter pipes creates better midrange but falls sooner.
Longer pipes also produces more power below peak torque while shorter pipes maintain torque power higher up. Being a racing only exhaust, you may be correct about it being straight inside.

It's all good as far as I'm concerned. different strokes for different folks. On that note, check-out the photo of this custom 899 Panigale exhaust. Mid-range torque might have to take one for the team but peak HP has got to be there assuming the track would allow it as it must be over-the-top loud.

What I meant was that by having the exhaust gases come out of the front, the connections in the rear do not require the header to extend to and enter at the front creating the additional curve external to the slip on.

The picture that you attached appears to be what MarkDucati bought off someone for his 899; he then had a cover fabricated to mimic an underbelly exhaust. You want to talk about loud? There are rumors that you can hear him start his bike in the surrounding towns near his home in Georgia.

Despite the various Italian engineering challenges I’m really pleased now that its fitted. I learned a fair bit about working on the Bike too. Air filter replacement was a job itself. Will get it out in the open air this week hopefully. Just need the UpMap download from the T800 but can’t seem to access the store. Have messaged Termignoni so fingers crossed.

It seems removal of the exhaust servo motor triggers the 'EOBD' warning light on the LCD. How do dealers remove this error message when they fit aftermarket systems? Eg; via Ducati electronics or with some kind of cable plug-in eliminator? I'm assuming there's a Ducati approved method for dealing with the exhaust servo removal.

Not that I care too much as the sound of the Termignoni's drowns out the warning light!!! :)

Termignoni? For the 959? And your dealer told you this? Judging from the V4 Panigale, Akrapovic is still the vendor for DP...

From what I've read on here and my own experience, removal of the exhaust servo motor doesn't trigger a visible error on the dash.

Of course anecdotal, I disconnected my servo motor harness but left the whole assembly in place and didn't ever get a warning light. It wasn't until a Ducati tech plugged into my 959 with their tool that there was any indication of an error. You might want to be 100% sure that the error is not from something else.

I want that exhaust!!! Must sound so LOUD!

It seems a common response for the EOBD light to come on after removing the stock exhaust. Ducati & Termignoni acknowledge this as the ‘race’ map is already installed and just unlocked when upgraded. So nothing untoward there. There are several independents offering plug-in hardware fixes and the exhaust provider also confirmed along with the Termignoni UpMap technical support. Never good to have the wrong lights illuminated but the upgrade should be available by the time Winter finally disappears in Scotland.

Termignoni was my choice. It may be old school Ducati but some things just belong together. Great there are more options these days as each to their own.
If this is a response to my post. You misunderstood.

I have a Termignoni on my 899 and love the brand. However, they only developed an upmap for the 899 and 1199 since they were the DP vendor back then. I was curious who told you they are developing an upmap for the 959 since the map has to be preloaded on the ECU and unlocked. Termignoni would have to have access to the ECU to do that.

the race map for the 959 and 1299 was developed with Akrapovic not Termignoni.

@TheBav1966
Perhaps you're referring to this:
959 16 OEM - UpMap with OEM exhaust
959 16 OEMN - UpMap with Termignoni de-cat

Not much if anything is out there in terms of information and reviews.
Is it real or most likely "vaporware" is anyone's guess right now?


Does anyone know how T800 works to add Termignoni map fit with 959?
I'm doing research to install Termignoni under-belly my own, no much information here in Vietnam
Personally, I wouldn't waste my time waiting for info about this T800 upmap stuff.
IMHO, Tuneboy, Rexxer or Rapidbike is the way to go if you want to improve your fueling.
