there is no performance reason to choose one over the other, pick the one you like the looks and price of

Thanks!! 14371ebu. Here in the usa we have one o2 sensor. No need for the other part number

if that was the case why would the factory put this system in it? it pops and flames with the stock exhaust you just cant see or hear it

@ got it. Thank you so much for clarifying mine and others stupidity lol

@@Jurshhh it’s not stupidity. It’s just not knowing and people repeating it again and again so it seems like it must be true

thank you! fingers crossed that date holds!

your tuner is the proper person to ask

I am definitely not a genius, but I greatly appreciate it Good luck ! I hope you have a successful , fulfilling career !

looking at their website, no , looks like they only sell a full system

you may be correct with the akra but I asked the guys at Toce and its pronounce like an s , toe ssss

no its not, stop it

I like the more quite leo vince, the dominator is too loud

I would wait and see what comes out specifically for the r9. I know there is going to be some different ones than we have now for the mt09 any filter that lets more air in is going to let more dirt particles in. no way around it. I have sprint filters on all of my bikes and have never had an issue just depends on your priorities, I know people with aftermarket filters with a ton of miles on their bikes with no issues

@@vcyclenut Thanks, I guess all I can do now is wait patiently lol.

@ you and me both

Sorry I don’t know

That is in every exhaust testing/tuning video I do.

Please be specific on what maps your speaking about There may be more maps that woolich will need to give access to. As I said in the video it’s common on new ecu’s to work with woolich to tweak what we have access to. I’ll be able to speak more to that once I start testing with the actual bike.

@@vcyclenut ok, I've made an assumption that @19:37 ETV Deceleration is the table which would Yamaha's engine brake control menu option use to set amount of the engine braking. However four maps which you showed looks same. So it is probably not the case.

@ it is the base engine braking map for each power mode. 1-4 There may be more maps that are taken into account if the bike has a few deceleration settings.

@@vcyclenut yes, and that (a) appendix in name would correspond to second EBM level.

Arguably the CP3 has best Quick Shifter in the Biz. Kaw has a lotta work to do to catch up, IMO.

none, stand out to me that I would call one the best

To be totally fair. My bike is putting down bigger numbers than it was when I first started testing.

im guessing you are in Europe? In the USA we only have one o2 sensor

It’s leaner in some areas and richer in others. Air fuel is never just lean or rich like most people think about it If you leave the intake side alone it’s not dangerously lean with the exhaust if that’s what you are really asking.

Pretty sure there are sound level measurements in the video

lol. I did say length of pipe was important. Remove the exhaust completely you loose 100% of the scavenging effect

I’ve always found the sprint to perform better than an oiled filter. Waiting on my distributor to get the sprint in stock.

No word yet but they don’t give me their plans for future development.

@@vcyclenut Thanks for the response.

It bolted right up with my usa spec bike.

It bolted right up to my usa spec bike

@@vcyclenut in what sense usa specs, did you buy the exhaust for the 2023 correct?

@@giostella6761 meaning some market 24 mt09’s have 2 o2 Sensors. The usa spec bike has 1. Yes it’s the 21-23 exhaust

Are you asking if a slip on is safe with the stock mapping?

the ecu is not interchangeable but all of the mapping related to tuning are identical on the 2 bikes because I set up my ecu's to the customers modifications and preferences, I can do 2 flashes for the same bike with same mods and they might not be identical but yes all things being equal they are the same

I’m guessing they are balancing velocity with how much it can flow for the desired rpm’s they want the exhaust to work best.

Thanks. I’ll check them out

Make sure you replace the muffler with at least as long pipe

it makes no difference in performance , its all personal taste

Crower has some for mt09 i wonder how wild they are. And how high they make power.

Yes and we will see other companies coming public with some

I don’t think they will be a direct bolt on as the areas that most of them bolt to are a bit different. I’m guessing a simple bracket would make some of them fit but hard to say with the lower fairing which ones without trying.

Mounting location beneath the bike will not be the same. Side-pipe will be required to be changed, probably lengthened. In short, no.

@ all guesses till I have a bike here

@@vcyclenut Guess is the appropriate word, I suppose. I know the frame isn't the same as the MT frame. The side mounted exhausts may be appropriate but the mounts will probably change. Belly exhaust may not work anymore due to fairings.

@ the stock exhaust is the same and belly mount

Glad it was helpful!

The act to equal the pressure between tubes. I’ve never noticed a difference in power when testing system with vs without cross over tubes.

@@vcyclenut I've wondered about it. I've seen it done both ways on expensive brands and I've never seen a rhyme or rhythm about the logic one way or another.

wish I knew, calculating safe piston speed and comparing to some other motors I would guess north of 12,000

@vcyclenut Im curious why moto 2 engine 765 are that much capable compare to Yamaha r9 wsbk. Similar engine to me.

@ internal component quality. Pure race motor vs production based motor

@@vcyclenut r9 WSBK is based from the oem R9 and moto 2 are based from the moto 2 streetbike. There is a street moto 2 model limited but it exist.

@@vcyclenut street model 13250rpm, moto 2 gp 14 200rpm.

that makes sense, I always say old school tuning knowledge dies hard

Two stroke and four stroke engines' exhaust systems function exactly the same way, but the engines have different needs. You can "tune" a four stroke just like a two stroke for the exact same reasons, but you're now dealing with mechanical timing principles related to poppet valves and cam lobes. If it weren't for the emissions regs, four strokes have a lot of potential left untapped. Cost is the biggest things with them, as adding a VVT system to broaden efficiency usually extends the cost of a given engine (non-superbike) beyond the market value of the category.

I don’t know where to send you in Manila.

yes , the akrapoivc is much more quite. Its physics, the larger canister is able to efficiently reduce the sound

I found it on ya website Do you have a discount code? I liked and subscribed!

no, sorry I cannot discount the shift lever, there is not enough margin on it

@@vcyclenut hey! I'm in Australia it says you don't post?! Can you use a shipping provider that SENDS TO AUSTRALIA? I can't seem to find this product anywhere else.

@ contact me through the website and we can set something up. Vcyclenut.com

@@vcyclenut all done

Damn that sucks!

The Hindle is next I looked Into the termi. Its expensive and I have to pay full retail on it. Its a lot to spend on a system for flash development that I don't think will be used much.

@vcyclenut thanks for the reply, I think I'll be going with the hp6 dominator exhaust, it's not too loud and still makes good power! I'll be sending my ECU to you soon, thanks for the content!
