GREAT NUMBERS!! Diavel V4 Dyno Day! How Much WHP?! 

Alright, guess the power numbers below 👇No cheating! All in all, the Termignoni was well worth it :) tinyurl.com/5z8n58nz

I installed the Termignoni Dragster exhaust, P80 filter , and Upmappe, No db killers on my 2023 Ducati Diavel V4 at 11,500 miles and I have put over 500 miles with the exhaust so I'm at 12,000 miles plus. I definitely feel the increased HP and Torque. Gas mileage went from 30 mpg to 25 mph but who cares. Also the bike always ran HOT at 210 F to 218 F. Now it runs at 187 F to 195 F. I feel like it finally sounds like it looks. It's a head turner and a Street burner.

Amazing video Mani. Damn I can't get over that amazing sound! Now the bike is complete, the look and the sound to match and the added power! Never was a big fan of the old Diavel, but this V4 got me 100%! I'm considering it as my next bike if I have the money.

ducati in the workshop called this the megamonster

Both those power curves are pretty nice, great gains on the map too. That TQ pop at low RPM is going to be spectacular on the street.

The air intakes from the Bentley Diavel V4 look so much better than the stock intakes, and are a nod to the OG Diavel.

Sounds so good and the gains were proper. BTW, that dyno guy is remaining loyal to the stock Windows 11 wallpaper.😅 EDIT: 9:43 Woah, that thing just rockets forward like a lightweight superbike.😮

I have the acro installed by ducati when i purchased the bike which cost me an extra £5000 but its worth 10k to me due to how it sounds. im telling you, its the best investment ever. I get superbike riders give me the thumbs up. it makes all the difference compaired to the stock. its supposedly 8bhp more than stock but i honestly dont know. its very agresive and looks amazing.

Ducati dealer near me has a new diavel with the akropovic race exhaust installed. 29k for the bike. Seen the exhaust alone is 6500 plus installation and tune.

Brilliant gains, looks more like the bike's been big bored, more torque everywhere 😎👍

I'm anxious to hear the sound comparison myself. from YT sound clips, I think Termi's sound better, more raw!

Sounds great.

I would like to know how the bikes feels after the work on twisty mountain roads, on the motorway it won't give you the real benefit. I will be installing a K&N filter and an remap once the first service has been done, I won't change the exhaust as I will be touring in Europe next year and some countries are cracking down on noise levels, Switzerland and Austria especially. Thanks for info and the mods you have done. I will also put an oil additive in the engine, Activ8, it reduces friction so the engine runs more smoothly and cooler, you can notice it on starting, the engine spins faster on the starter.

Impressive. Are the torque waves related to wheel balance or fuelling? Cant wait to see when BT finetune their package too.

I really like the look of the stock exhaust and wish there was a way to make it louder... anyone feel the same and attempt to modify stock while keeping the 4 pipe look?

Wish Dat air intake part shud also b in red ..dat plastic ting spoils d look

Shame Ducati didn’t put sf engine in this bike and electric ohlins. Would be one hell of a bike

BT time

And the motor didn’t let go like the you know who (bmw).

bro loudest exhaust for Kawasaki ninja h2

Ducati specifies 168 hp at the crank for the Diavel. You have measured 148 hp at the back wheel. Supposing there is a 15% loss in power from crank to BW it means 148 at the BW is 174 hp at the crank. That is better than what Ducati specifies. 155 hp at the BW means 182 hp at the crank. And this is without a tune? But then again who cares about crank horse power figures.

My WR250 sounds better with stock exhaust...lol
