Shocking Results V2 Bayliss Akra Exhaust on the Dyno

[@JaretCampisi]

So stock our V2 made 134hp on the dyno and after the exhaust, filter and flash it made 133hp on the dyno. Considering this exhaust costs $6500 plus tax and installation that is a bit depressing...regardless it does sound way better and it still shaved 20lbs so its not all bad. Not sure if we missed something here? Let me know your thoughts in the comments below...

[@rabiaboksmati4406]

another banger!!! whats pops new bike gonna be?

[@JohnBrown-vn2qw]

what the torque curve look like

[@LOCKHIMUP2024]

Depressed ⁉️ I am confused ASF ‼️ Has this ever happened Since you've been doing this ⁉️🤔🤨😳🫤🤷 Something has to be with the flash, I've never seen this before.

[@clubstyleridahd4695]

What Made the previous v2's get into the 150s that this one doesn't have?

[@rafaellastracom6411]

The V2 makes 155 hp at the crank, at that rpm your talking about 12.5% losses and that puts it at about 134 hp at the wheel so the numbers are good. The problem is the full system added nothing and at $ 6,500 it is clearly not worth it. Shit happens albeit disappointing in this case. @@clubstyleridahd4695

I have been remapping my 1200 multi (2013) for about 4 years now. Let me specify that. I have, without any measurement devices (dyno etc..) created, essentially from scratch, a set of fuel maps. I have done this using a lengthy and very painful process of finding the optimal curve through experimentation. Yeah, yeah, I know all the specialists will say this can't be done. All I can say is you should try my bike. I have learned a lot in the last 4 years (just over 120 experimental maps in that time). One of the things I have learned is that the engine responds to very, very specific fueling at every throttle % and rpm. The fueling has to be within less that 1% of optimal for the engine to start responding in an ideal way. My engine now runs smoothly and happily from about 1700 rpm, and will roll on smoothly from that point up. Torque is phenomenal all the way up the rev range. Here's a reasonably quantifiable example of what I have achieved. The 1250gs on paper produces 135 Nm, which is 10 Nm more than my bike. The other day I ran across 3 of these, and they wanted to play. I found that I could stay with them with absolute ease anywhere through the rev range - at lower rpm (from 3000 up) I could quite easily pull away from them. As soon as the revs went up to 5000 or higher, it was like they started applying brakes instead of throttle. A lot of the time (especially at higher revs) I wasn't even using full throttle. I don't think I ever went over 7000 rpm. It was a lot of fun, and no doubt very frustrating for those 3 guys. Another comparison. I also own a 2018 multi (the 1260). Because it has a different ECU, I can't use my fuel map. The difference in torque between my 1200 and the 1260 is nothing less than staggering - anything below 5000 rpm the 1260 is way, way slower than my 1200 in any gear. (I guess I have to mention that the 1260 produces more power than my 1200 from about 7500 rpm); What I am trying to say is that producing an optimal fuel map for a ducati twin is not trivial and not obvious. If the fuel map is off by 1% or more, the bike simply will not run properly. I have looked at many commercial ducati fuel maps - with the experience that I have gained, every single one I have seen looks badly wrong, not even close to an optimal map. Most of them violate even the most basic principles I have found to be sacrosanct when crafting a map. If you can extract the fuel map you were provided, I would be happy to comment - there may be simple things you could try that could provide a better result.

[@benjibradshaw69]

Most tuners just throw aload more fuel in at the bottom end. Poor quality maps with zero development.

[@rs8197-dms]

@@benjibradshaw69 I agree. The maps I have seen show close to zero understanding of how the engine works.

[@projector7141]

Thanks for sharing this. I guess it gets more complicated when you also alter the ignition maps. These bikes have separate maps for each gear! And 4 throttle maps. Plus all the maps for ABS, TC etc.

[@tachena]

Crazy, my v2 dyno'd 154 with just the Akra Muffler and the the Racing map.

[@markroccophillips4243]

@JaretCampisi - I have a V2 Bayliss with the full titanium Akrapovic exhaust system, but I used a Woolich ECU flash and full Dyno Tune, my results increased significantly (148RWHP). I'd suggest that maybe the Dyno was out of spec, as even with the exhaust system, you should still have some gains there. Otherwise, the UpMap either wasn't for that bike, or had corrupt files.

[@thearch1tect249]

You are so lucky to have your dad to be so awesome! Makes me smile when ever the old man is around. Merry Christmas to you, Christina your pops and of course Dado!! Ride safe.

[@Topendz]

This is why it is important to get some serious miles in stock form to get to know your bike throughout the rev range and in all conditions. What matters to me is seat of the pants HP and smoothness and you can only appreciate that once you know the characteristic of a bike in stock form prior to any upgrades

[@projector7141]

This is a great point. I guess it adds to your learning too - like exactly what changes with new equipment.

[@neilparry14]

I have the 1299S and out the full Akrapovic system on it with the upmap. I took it to the dyno and got 179 BHP. The technician said it was running incredibly rich. He then remapped it (6 hour process), and re-dynoed it and got 209 BHP. That was 3 years ago and the bike is still running perfectly so it’s reliable. The upmaps aren’t worth the memory stick. Get it remapped by a professional and reap the true benefits!

[@kemal.yetim.]

Papa is back wit his legendry jacket, dude love ur jacket chracter kudos 1 million👆🧿🎨🎯

[@n.elliott9122]

If I recall 650ib did an early V2 with slip-on, dyno comparison and it gained 12 or 13hp with only a slip on.

[@graham5318]

Noticed that you only have 320 miles. Did the "break in" service get done? If not, maybe something is intervening and limiting power? Or maybe it just needs to adapt as you suggested. Dyno graph shows some losses in multiple rpm ranges. I'm sure you will get it sorted...then maybe a redo at the dyno 🙂

[@colinoz]

I was thinking that too. Ducati's first service flashes the ecu and takes it out of the break in period. I noticed the difference after the first service on my V2.

[@wesleythompson5885]

Yep also super tight engine probly will loosen up a little bit

[@JaretCampisi]

I thought about that too BUT I thought the akra flash would remove all of that regardless? We have a bren flash on the way. We will give that a shot and see if there are any different results on the dyno.

[@alanwharton8855]

I have a 2022 bayliss and those dyno results are a surprise to me, im about to add a Arrow slip on to mine with t800 up map n hope for at least some improvement. improvement improvement

[@JaretCampisi]

keep me posted with your numbers!

[@funcool32]

Did you put the Arrow slip on? I'm thinking of putting Arrows also, so would love to know how you went.

[@alanwharton8855]

No, warranty up in October, will sort after as Ducati won't cover arrow slip on.

[@funcool32]

@alanwharton8855 good luck with it. I've heard the Akro's on the V2 and they sound awesome. Haven't heard the Arrows, except for KZbin.

[@Mike-dd8bd]

I wasn`t going to enter this time around, but after hearing this thing on the dyno I couldn`t resist.

[@n.elliott9122]

Something is up with those numbers. I have seen a 2022 V2 with a full Arrow and tune putting down 152HP and 79 Trq at the rear wheel. Find another tuner or reload that map and try again.

[@Atlan_tis]

152hp is with AIS Delete, other wise it’s up to 146 to 148hp , AIS delete plates are cheap

[@J1Z06]

500k! Congratulations to You!!

[@steveboyle6891]

Yeah that doesn't make sense, think you would gain at least 5hp. Maybe there is some adaptive learning like you said with the reflash. Sounds good though! 👍

[@JaretCampisi]

Yeah we have a bren flash on the way. Gonna put that on and put it on the dyno to see what kind of difference that makes.

[@handiyohanes01]

Use an AFR tools and full mapping the fuel until the AFR are ideal, that will increase the power

[@Atlan_tis]

Something is wrong, i have bayliss V2 with T800+ I tried both EVO map and Race map and it pulls really good in Race map and you can feel it a lot over stock map and I do have Arrow exhaust and Sprint filter

[@JaretCampisi]

yeah we've got a bren flash on the way :)

[@russssh]

Me too! Was night and day difference.

[@bigandbad9]

My BT moto tuned v2 with PO8 and a slip on made 145 wheel. BT moto is the man

[@kensnyder2340]

Sometimes it's hard to beat the factory stuff. The Manufacturer's do a lot of tuning to get the factory power out of these bikes that they produce. The sound definitely improved. But cost return on investment, not good. I know every bike that I have put a full header system on has lost some bottom end.

[@projector7141]

I also think the stock exhausts are beautiful and most of the HP gain is from the filter that comes with aftermarket pipes and the map and the decat. But that's just imho coming into the bike world from race car world.

[@BenefitMe1000]

Gonna be honest with you Jared the bike has “break in” period for a reason. It’s a mandatory calibration for the rotating assembly to adjust evenly to make power more efficiently. Flashing a tune on a power unit that hasn’t been broken in more than likely wasn’t the greatest thing for it either. The likelihood of a $6500 exhaust causing the bike to make less hp? Not very. I have an arrow slip on, on mine after break in was complied with made 13hp+ with a Bren tune up map. I’d send the info to Bren see if they can help out

[@garyb931]

He Jaret was the rear wheel slipping, I noticed the ABS light flashing. All the best for Christmas and the New Year. Cheers from Australia.

[@chrisbatham861]

I wondering weather the upmap install correctly. Hopefully you can tell the problem next episode..

[@Bayliss21]

My bike with bren tune and air filter and this exact exhaust is close to 147whp. It also pulls with a V4 down the back straight of COTA for at least the first 1/3 of straight. Numbers are low. Akra tune or brentune?

[@JaretCampisi]

yeah getting a bren flash to see how that does

[@alexcallas8222]

If Christina decides to get back on a street bike, that Scrambler is obviously the best choice. Look how the scale and size is proportioned just right for her size. Also, less weight than other Ducatis, but most importantly: tall and wide bars! That's the best way for a newer rider to learn how to countersteer, not by starting out with clip ons.

[@drewgayle8325]

it is still one of the GREATEST bikes around .

[@sandysandor1699]

If you change the exhaust: Do you need to change it again to get the state inspection or not???????

[@Lar308]

I just got the full system termignoni exhaust on my monster 937 plus and the result was absolutely amazing in sound and performance but that only cost €2,500. There is no way I would consider paying that much money on upgrading the exhaust on my 2022 Bayliss even if it gave it 150bph because that's just pure robbery especially when the stock system is super loud and looks pretty good too.

[@DoraTheNinja]

i would do a different flash you are right these usually sit in the mid 140s with a tune and exhaust

[@leadsled8961]

It is only supposed to make 153 PS (150hp) at the crank.

[@paulcabin8]

Happened to me too. You have to do the break in service to have full power unlocked 💪🏻 Same thing with the v4s ☺️

[@Knahledge1911]

I've heard this before as well. I dunno if it's true. I just did the full first service this past Saturday at Ducati of Sanford. I haven't been able to ride the bike since the service because it's been raining everyday, but hopefully it stops soon so I can get on it.

[@TheRealBhuado]

absolutely not. only BMW has this. and that is only a rev limiter. which i guess it is a power limiter.

[@Image-X]

Hey Jaret, this is off subject BUT you MUST get the 2024 698 Mono. Have you seen that thing? It is way awesome and I think I’m getting one for sure!

[@chrisbatham861]

Thanks I'm going too get my Bayliss checked on the Dyno. As brought the same system and upmap from Ducati. I would make Ducati sort that issue.

[@michaelmitchell5909]

Dude the sound is incredible....wow. Hey what was the red ducati teens was sitting on in the showroom while u were waiting for the tune?

[@mike423439]

FYI Jaret. Akrapovic is actually pronounced "A crap o vich" This used to be on the website but when they discovered what crap ment in english, they changed the pronunciation to "AK Ra POV IK" Only the charter customers remember this. I bought my first one back in 2006. Full titanium and still on my 2005 Busa. I absolutely love it.

Actually it’s pronounced “ A Crap Oh Shit”.

The manufacturer “break in” is not a suggestion it’s facts from the people that build these bikes. You follow them first, then do your aftermarket upgrades. Simple as that.

[@superbikesquadracer]

Your dads diavel 1290 has a huge schrath mark on the paint (Right hand side intake fairing)

[@antoniozamboni7979]

You installed a few things correctly, but by the sound I would say that it has a full catalyst. install a bigger air flow, a stronger fuel pump and take it to mapping like for example Chriss more - more mafia. that engine, with everything well done, must give a minimum of 250 hp.

[@99gpandy28]

250hp out of V2 959 ,reckon you need supercharger too achieve those numbers

[@munter10]

250HP?? most people go to sleep before dreaming, ....in your case . . . not so much lol

[@Joe_Av]

Just me or does it look like Pops' bike has some scratches on the right side front fairing towards the top? Hopefully it's just a lighting/angle effect and that he didn't drop it.

[@ginopartosetiko9292]

you should let chris moore do a live dyno tune on it. He'll squeeze every inch of hp out of that ducati.

[@GeorgiaGrowGuy]

Moore works on Japanese bikes.

[@jedsampsel7746]

Yeah that doesn't seem right. Even if peak numbers were not better I would expect more power across most of the torque curve. I know some dyno's you can set it to correct for temperature changes and maybe it was related to that vs he first time IDK. I imagine the upmap is on the conservative side, but still should be better than stock. It would of been good to know the air fuel ratio ( I didn't see that unless I missed it) to make sure it isn't way off causing the low power numbers.

[@jeffp9246]

What did your last V2 build add?? Had the same exhaust.

[@JaretCampisi]

145hp

[@snak-s7952]

Yeah, I was hoping for more power too. I own a 2023 Bayliss and I am having a lot of hardships with it. To start my idling is terrible. Too low and shuts down at every other stop or light. The clutch is hard to get right. Last month my rear break starting seizing with my Rizoma pegs, so that almost killed me while driving! Gotta fix that before next year. My Akrapovic is like yours. No recognizable power difference for me. Love the look and sound but functionally, I am so disappointed with my Bayliss mechanically speaking. This is becoming another expensive Italian vehicle. Still awesome though

[@Atlan_tis]

I have 2022 bayliss, never had an issue, over 2000 miles , never had issues with rear Rizoma Pegs

[@SeanDonDada]

A brent tune will fix all your issues

[@anthonys6385]

Was it a Bren flash? I've seen a +10 hp run with similar mods

[@bill_4359]

No, a Ducati map.

[@JaretCampisi]

Nah it was the Ducati upmap that comes with the akra flash

[@anthonys6385]

​@JaretCampisi something similar happened to my monster 821 with a termi map. I fixed it by adding a rapid bike auto tuner. Love the build series for this

[@1canstuntman]

Bet you forgot to unplug the O2 sensors and not sure about the Akra but Arrow, termi etc also require that disable the exhaust servo trigger signal in the ECU. Thats very very suss and shocking for a full system... especially at that price point!!! Loads of half system Arrow vids getting high 147-155hp at the rear wheel.

[@kupalisky3553]

Can you feature some Aprilias? Too many ducatis on this channel

[@wopadobop]

still breaking in too. keep that in mind.

[@Maree.612]

Having a full system doesn't necessarily make more power. Aftermarket systems are lighter, but some slip-ons result in more power on the dyno. Chris Moore and Brock Davidson proved that.

[@age6439]

Still a fantastic bike Jaret! did I see you had a new car in your garage?

[@gt5552]

Teens loves shopping for the next build bike.

[@hrsjohnny]

maybe there is no power gain but it sounds better than the V4 :)

[@Francus6969]

Still a hell of a beautiful looking bike

[@rabiaboksmati4406]

Less power?! gotta be the flash..

[@lukotoystv]

maybe because Dado wasn't there so it didn't perform. LoL... Looks and sounds badass dude. I'm sure you all gonna fix the problem.

[@712_Performance]

Get a proper map and dyno tune that’s fully gone thru by someone like Nate at 2 Wheel Dyno Works instead of “up maps” and it’ll be better.

[@ricardoabreu69]

Something electronic maybe is cutting the power. 🤯🤯🤯🤯

[@CbrRob]

Remove the flash and get a custom map.

[@JaretCampisi]

we've got a bren flash on the way

[@russssh]

Should make about 145-155hp after a full system and air filter. Something isn’t right with yours. My Bayliss was transformed after a full termi system and P8 filter with tune.

[@hssw20c24]

The v2 engine makes 155hp.. not to the wheel. what you're saying is impossible unless they do engine upgrades lol

[@russssh]

I thought so too until it was dyno’d at 155whp at Cube Performance, a Ducati specialists who run the Ducati Australian Superbike Team here in Australia. The dyno could be inaccurate though as it seems too high but who knows?

[@Gixflix1]

I'm thinkinking maybe Ducati got it spot on at the factory. Sounds nice though....🙂

[@sammyboy211v]

My 15 year old V2 Aprilia RSV1000R made 132hp on the dyno...

[@MatrixDesigner85]

Sounds good, looks good the hp change wouldn’t be on my mind 😆

[@lold6130]

It would be disappointing if this was a track bike but for the road it's no biggie. It still pulls 135 mph in 4th.

[@yiannishayabusaofficial]

AWESOME video amazing superb top

[@ChrisMHDFilms]

The only reason why you didn’t get higher numbers on the dyno is because it was done in 4th gear. Take it back to the dyno and ask them to due a 5th gear pull. BT-Moto does pulls in 5th gear this is why he gets higher numbers. I bet if he would do it in 4th gear he would have similar results.

[@JaretCampisi]

I thought 4th gear was the universal gear used because it has a 1 to 1 ratio?

[@ChrisMHDFilms]

4th gear ratio is 25/20 & 5th gear ratio is 24/22

[@HarrowedDreams]

Show the entire dyno graph WITH afr! That's where the proof in the pudding is

[@cocomatef]

Just a clue- no SBK race team is using underbelly exhaust, it´s just for aesthetics(ugly).Needs a lot more pipe for hp increase.

[@jasperpearce8316]

Brentuning to the rescue!!!!

[@Image-X]

Something is definitely not right. You should still be getting higher numbers without another flash. It could possibly start producing more after it learns. Only one way to find out. If it still doesn’t produce like it should….. dump it in Ducati’s lap to fix.

[@ChaseN194]

Should have brought this bike to EDR

[@ravenmoto310]

Sad. Mani just unwrapped one for Xmas, so in time we will see what he gets.

[@motochiptuning]

⁠its always the case buddy :) your usa tuners are 99% autotuners,copy paste handhelds noncence flashing etc. . suggest u find normal tuner and do it on dyno cistum tune individual cylinder tune. On V engines its mandatory. All other tuning is waste of time and money

[@isaalghazi9131]

The Stock Ducati 'Up Map' is usually GARBAGE. Best to get a custom PROPER tune for the engine to take advantage of the better flow from the Akro system.

[@Ducatirati]

[@michaelmitchell5909]

I thought the flash was from acro?. That dude that did the dyno had to do something wromg.

[@JaretCampisi]

the flash is from Ducati and comes with the akra full system....we did the exact same thing on the dyno that we did with the stock exhaust

[@youmatt2]

let me explain as owner: you made a mess, the Ducati Map (please stop call it “Upmap”, it’s a completely different thing and company) is tuned for the original filter, with the Sprintfilter now you a have a fuel/air ratio too lean, you need to adjust with a manual fine tuning, not another flash, please do not make the mistake to put another over-layer of map above the ducatis r-evo

[@dmartin23]

you haven't done the break in miles. The oil also needs changed after 600 miles to the correct viscosity. No wonder your dyno results are out, you haven't even broken in the motor. Ducati also advised that you don't rev the bike past 7k for the first 600 miles.

[@83jward]

Sounds like it needs a dyno tune instead of a flash.

[@712_Performance]

This. “Up maps” are always trash. Proper tuning will wake it up.

[@jacktupp1427]

Why is it people are so consumed wirh hp figures? Torque is as important. Putting those aside more importantly is the A/R. What is that throughout the rpm range? If you were on top of these things you could answer your own question!

[@rexwilliams4273]

i thought you dyno in 5th gear and not 4th

[@nickscarantino304]

Dude, Theirs nothing wrong as long as you enjoy the music coming from that insanely beautiful V2! However, I can appreciate your disappointment after spending $6500. Dollars on an Akrapovich exhaust expecting a bit more HP? Keep in mind that the Dyno readings are just numbers for conversions over a beer, a couple of HP’s on the Dyno are almost meaningless? However, your performance gains from the weight savings should be noticeable from the seat of your pants! The rule of thumb is for every six lbs. of unsprung weight eliminated from the vehicle is equivalent to a 1 HP gain in your HP to weight ratio? The true measure of power that can’t be measured from Dyno readings but rather from a scale? And for every three pounds of weight eliminated from the wheels it’s an equivalent to a 1HP gain in HP to weight ratio because rotational mass doubles? In addition the bike is going rev easier & acceleration out of corners quicker! Because the engine has less weight to bare? Eliminating wheel weight with carbon fiber rims is going to be mega! So you did great although a little expensive? That single HP difference is really no difference at all, Dyno’s are notoriously inaccurate for a number of reasons on many levels, go Dyno at a different facility on a different day, with different weather conditions using different pump gas & you’ll get different readings? That Dyno run showed me just how good the engineers & designer at Ducati are at their jobs! And that you don’t need to spend a lot of coin unless you want to hear some louder exhaust notes coming from your motorcycle? The very best way to make a vehicle faster is to first put it on a diet! Like you have already, enjoy the bike & throw the Dyno readings in the Bin!
