Ari's got a new project! This Yamaha YZF-R3 is being transformed into a racebike, and one of the first steps in the development process is exhaust testing. In this vid, Ari weighs, installs, and then dyno tests Yoshimura's R77 exhaust, providing full results on power and torque gains, weight savings, sound, and the installation process.
--
It's not often that you get honest, empirical data about aftermarket exhausts. Well, if you're in the market for a pipe for your Yamaha YZF-R3, you're in luck, because Ari Henning has put Yoshimura's new R77 race exhaust through the ringer. Watch the video to learn about what this pipe has to offer in terms of weight savings, power gains, and sound. Ari even tests the pipe with the quiet insert installed. You'll be surprised by the results!

Well done Ari! Some bikes require an insert to make more power. For Yoshimura the R3 is one of those bikes. Kudos for showing quieter bikes can be made more powerful. Oh and sorry about the foam. We want to protect the systems the best we can :) we are working to not use it in the future.

Yoshimura Research and Development of America, Inc. send me an exhaust for ninja 300 please, thanks y’all the best 🤓

@jimbenson3926 6 лет назад

Hello Yoshimura, Bit of feedback for you, for my GSX 1400 i had fitted Yoshimura stage 1 cams and 4 into 1 titanium machine bend pipes. Brilliant got 20% increase in horsepower and a 2 stroke like power band at 5400rpm. The downside is the pipes scrape like buggery at the 4 into 1 collector. I've had a mini bash plate made up and the gouges cover a area of 25mm by 80mm.

This should be a standard for all dyno videos!

@ShockTech326 6 лет назад

Did somebody say R3 videos?! Keep 'em coming Ari!!

@theFrEAk1171 6 лет назад

Great video! Really excited about this series. This is exactly the kind of content I would like to see from Motorcyclist in the future!

@noahlazarus 6 лет назад

Awesome running into you at Thunderhill. This bike looked wicked in person. Will be sweet watching the vids of you putting it together. Good luck avoiding those DNSs next season. P.S. MC garage for the track. Do it!!!

@emiliobarajas9408 6 лет назад

I'm doing the same thing to my R3 specifically to race in CVMA next year, I'll be putting the same exhaust on next month! Keep up the great content excited to see what comes of your build! See you other there!

@pauljeanettecooper4149 6 лет назад

Nice to see a project bike. It would also be good to see it not take on too many expensive components if possible.

@gzone11ify 6 лет назад

Now that's why I'm talking about, love this kind of video. I can't wait to see the progress on the build

@u9Nails 6 лет назад

I am amazed at how good the stock exhaust is with all that smog control stuff. Heavy probably due to a lot of iron, that's expected. I'm curious if you'll open the motor and port/cam this bike?

@benjytexas 6 лет назад

Just got a R3, now it's time for an exhaust. Thanks for the work!

@sennsir 6 лет назад

WOW! Who would've thought that a baffle could be the cause of hp gains! Nicely done!

@chrisredfield3240 6 лет назад

Must have been running to lean even with the new map.

@austinmiranda8028 6 лет назад

Hell yes, looking forward to more episodes with this bike

@Anand-uz5jo 6 лет назад

Nice work Ari. But i cant help but notice that the factory model R3 in India has 43.5 bhp. Big fan of your videos, really helpful. Also I'm hoping you'll make a detailed video on the track mods you are doing on the R3 just like that video of your RC390. And a comparison too with performance figures and lap times and on board videos. Thanks in advance 😀😬

@sourabhpurohit4140 6 лет назад

The power figure Ari is mentioning are at the rear tire. The manufacturer claimed power is at the crank.

@Anand-uz5jo 6 лет назад

Sourabh Purohit oh didnt notice that. thanks for the clarification

@entitykeeper8869 6 лет назад

I have been following Ari's build. Pipe 38.4hp, Pipe & PC5 38.79hp, Pipe & Re-flash 39.35hp. So a pipe & re-flash about a $1K to make 6 more hp. About 40hp & 20.5tq. That is rear wheel power. My 1978 KZ750 twin was about 45hp at rear wheel. Hmmm.... This bike is faster than it appears to be.

@berkayt5319 6 лет назад

@gronkgrunk 6 лет назад

Really liked this vid, showing us what we need to know. Great job again guys. Will follow the progress of this awesome R3!

@Masterdome95 6 лет назад

I have similar results with my '17 CB500F, installed a Powercommander V with IXIL decat headers + Yoshi R77. Gained 3HP and 7Nm torque from stock after the dyno run.

@guiluvimont 6 лет назад

I do not know how the Power Commander mapping works, but here in Brazil, in the championship that exists of motorcycles YZF R3, motorcycles have about 42hp in the wheel (about 48hp in the engine), only with preparation that includes race exhaust, air filter and iridium spark plugs and of course, the electronic preparation. And one of the preparers that I know uses the original ECU of the bike to reach that power, some others uses Rapid Bike or Bazzaz..

@topgun8683 6 лет назад

Sweet ride Ari, that's the kind of bike you can rip on at the track !

@GETUPANDGO 6 лет назад

Nice, that's awesome, now I'm even more determined to get myself a new exhaust

@INNOVVDashCam 6 лет назад

Great test! That exhaust pipe looks really shinning good-looking!

@gooondie 6 лет назад

Love this! Turn this into a new series!

@outty77 6 лет назад

I have that same pipe on my F800GSA - just swapping out the muffler saved 5 lbs.

@johntran1014 6 лет назад

I found 2 Yoshimura exhausts at the markets, with rust all over the thin metals that are held on by the little round rivets ( I think they're called ). I was going to buy them but seeing rust also inside the cans, I let it pass. I was thinking if its stainless steel, it shouldn't rust at all.

@definitelynotpewdiepie 6 лет назад

Excellent video. I love watching race bike builds. Please do more of these.

@imadecoy. 6 лет назад

I think the full race Akrapovic exhaust for my bike is designed to work with the stock mapping.

@dizi17 6 лет назад

great idea for a series. right on !

@justinp1471 3 года назад

Awesome video really love your channel. I was a bit surprised thought there would be a little more HP gain. Price to performance is super high. Nice bike, I think it would be a wicked track bike once complete.

@mikeskidmore6754 6 лет назад

I don't recall any difference in sound .. I still have the stock exhaust on my Yamaha FZ-07 because I don't like loud.. I think they still have race classes for Yamaha RZ-350 that would be a little more exciting to ride.. You still have the buddy pegs on it.. Aria @Motocyclyst Magazine .. I subscribed to Motorcyclist and others for years before internet ..

@mihirkulkarni07 6 лет назад

Hello Ari.. When can we expect more videos on your R3 build up? I loved this series.. I was hoping for more..

@peterhird3542 6 лет назад

Ari can you do a video explaining the use of a Power Commander? I hear a lot on posts about their use but I’ve never installed one. Great video by the way👍📹. Cheers

@cavesuki8510 6 лет назад

This was my first bike it was AMAZING!!! & fun as hell, coming off a kawa & ninja this one was the best imo

@ImConstantlyConfused 6 лет назад

Thank you for emphasizing the point that you need to adjust the tune after the exhaust change. It bugs me so much when people slap on parts and think that's all there is to it. If you change the type of air filter, you need a new tune (or carb re-jetting for carbureted bikes) if you change the exhaust you need a fuel adjustment... You don't want to end up running lean because you cut corners and half-assed the job. BTW, that exhaust sounds better (on camera at least) with the baffle in. Great job with the video!

@ALMX5DP 6 лет назад

Ari, does that mean you'll race with the baffle in place? It cant weigh too much at all and if it can repeatedly make an ounce more power, it should be worth running. What are your thoughts?

@isumairuchiru 6 лет назад

Wohoo.. gonna get R3 soon and here you gonna project on R3...l

@natural9743 6 лет назад

Always get what you pay for-great vid

@sourabhpurohit4140 6 лет назад

Hey Ari. Always great videos by you. Keep them coming. But what about the RC390? Do you still have it? I think RC is the best track bike in it's category.

@MC-Racing 6 лет назад

Nice little track-weapon.. looks good. and i love makinge a small displacement bike a racer :-)

@benb2058 6 лет назад

When you said you were going to re- dyno the bike after installing the baffle I knew there would be a twist ! pretty awesome to learn that .I never would have figured more power with the baffle in. I have a two brothers exhaust on my V-Strom 1000 wonder if the p1x power tip would kill my d-cell pop and give me any more power??? It's a little on the loud side anyway it sounds like a good reason to try it thanks for the tip!

@sanjo7ph 6 лет назад

Hi Ari! Great videos. I'm a big fan.

@JamieS1992 6 лет назад

my R3 power wheelies now have an M4 slip on power commander K&N air filter smug block off plate going to get it tuned soon with the commander i am hoping for around 40HP also I keep my baffle in remove the baffle and give it a try and you should notice the loss of engine braking and it was enough for me to not ride as well so i popped it back in

@Nalopotato 6 лет назад

18 lbs! Mother of god. That's as much as my FZ-09 stock pipe

@martinarnaudov3566 6 лет назад

Good evening to all, i saw that Ari sad something about "if you run a full exhaust system it is not very good without a REMAP". Can someone explane why exactly you need a remap? Is it bad for the Engine somehow ? Or it's just not benefiting at all from the full exhaust system. Thank you very much and have a good night :)

@kornboy22 6 лет назад

Why did you not tune the power commander on the dyno instead of using a fixed map? Fixed map is pretty good but tuning for an individual bike is better.

@Frenchcrop 6 лет назад

Cool project Ari.

@dugwthree Год назад

i did that years . Spears racing set me up with fuel controller and said to use the baffle also . My exhaust has the full carbon fiber muffler. was packaged the same as yours.

@KizzaHigh_OCTANE_HSV 6 лет назад

I'm curious. Of all of the engine sizes you could have chosen from why did you choose a 300cc bike? I would've thought maybe something in the real of 600cc

@Cutlerylover4life1 6 лет назад

I always thought 300's would be a really fun class to race

@manupmukherjee 6 лет назад

Why not Akra or the M4? Akra offers better gains throughout the rev range.

@radrcer 6 лет назад

Clear and concise video. Thats how they should all be. Id rather track a stock 600 than a built 300, but to each their own🍺

@Siper2 6 лет назад

Great video, Ari! It's all a matter of averages of course, and a 10%+ power gain is pretty awesome for not much time invested! Those spring pullers do look pretty sweet. I learned a trick when I was installing a used center stand on my '94 Yamaha, a couple years ago. If you DON'T have a spring puller, bend the spring in half as much as you can and stick a couple pennies into the gaps. Then bend it the other way, and repeat. That adds length and allows you to simply slip the spring in place. Then extend it and............poof, full refund. :-]

@caruser4 6 лет назад

Great idea on a build series!

@mrvwbug4423 6 лет назад

Can't wait to see this thing on the track (you will post track vids of it I hope). What kind of work has been done to the suspension. I know stock R3 suspension is fairly soft and probably not up to any serious track riding.

@camillecorpuz 6 лет назад

Great vid and awesome project! I'll be following this closely as I'm putting together my first track/race bike with goal of racing my R3 next year. Was looking at the Carbonin fairings. How would you compare the quality, materials, and ease of install to anything else available for the R3?

@andrew8502 6 лет назад

love these sort of vids!

@randomtom 6 лет назад

Any chance we can get a verbal or text insert on the weight in kilos for us outside the US that's don't use pounds and ounces? :)

@bramantyo2505 6 лет назад

Thats 2 cylinder sound awesome. Can u make a video about engine block off plate? Some say it can remove the deceleration "bang bang" sound on the aftermarket exhaust. Thanks

@treycarter440 6 лет назад

On most bikes it will reduce it since you aren't shooting oxygen into the exhaust, but youll still probably get some on decel. My 600 sure does and it has no cat or air injection. Its just from being tuned a lil rich on top, pops when you let off due to the excess unburnt fuel in the exhaust.

Bike Almighty Guru, i love your videos.

@DEeMONsworld 6 лет назад

Perfect. Exactly similar to my results with my MT07. more power with baffle in(LeoVince underbody in my case) that out, Curious why you opted for a power commander rather than an ECU flash. I ran a custom flash by 2WDW and an active tune WB Lambda sensor and ecu mod by FTECU.

@RTK171 5 лет назад

Can you cut the header pipe down to bring the exhaust can back so it doesn't hang so far back? From the bike Great vdo

@ruikazane5123 6 лет назад

Then Ari would teach us how to manually tune the mechanical systems and a larger volume injectors, right?

@hejmuesli 6 лет назад

Ari could you and Zack do more content with older used cheaper bikes? Maybe revisit bikes that were great bikes at their time. Or just go shopping for bikes that you would consider yourself either if you were strapped for cash or if you wanted a 2nd or 3rd bike to compliment the one(s) you already own.

@davehillsden 6 лет назад

they did a video where they set a modest budget and went and bought bikes and gear and went for a ride up the coast. I wanna say about a year ago. Go to their page and you should find it. Also the channel 44teeth in the uk has just started this same project as well with an old srad 750 and a zx7r.

@davehillsden 6 лет назад

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IwePyWF36TU.html there you go. Ari and Zach took $1000 each and bought bikes.

@hejmuesli 6 лет назад

I know this, and thank you :) I want used and older bikes to be a reoccuring theme in their channel :)

@hejmuesli 6 лет назад

Again, thank you. I saw the 44T video, too. I just want more, more, more of this sort of content :)

@ruelpalma9724 6 лет назад

Hey ari just wanna ask as u mentioned u said if you had a full syatem exhaust you can’t be running without a power commander installed in your bike but heres my question i’ve been running for almost a year now since i ride my r3 without a power commander is there any problem in the future if i will keep ot like that? Run with yoshimura full exhaust system pls let me know thanks

@JensEskildsen 6 лет назад

Would be awesome with a baseline for the stock motor with the fuel controller added.

@entingbhetoycolags9952 6 лет назад

Hi! Ari can you run also a dyno test for cbr 150fi i just want to know what is the good exhaust (mufler) for that small 150cc engine... thanks... im a fan and subcriber...

@RideWithAyan 6 лет назад

Nice bro

@archetypex65 6 лет назад

My question is what is the dollar amount per horsepower value. I'd like to see an Roi on that. I'm guessing that the yosh system had to be running somewhere between $500 and 1k? I don't know what a Power Commander goes for these days I'm out of the loop... but it seems to me that's quite a costly investment for 3.6 horsepower gain and basically no torque increase. Which means you're not getting any more power off the corners but just straightaway speed. I'm wondering if there would be a much cheaper way to gain one or two horsepower for less than half the cost of your investment. Is there a chip available to change the engine mapping without installing a power commander? Will there be a cheaper alternative to the Yosh system maybe a little heavier but still lighter than stock something that flowed a little better.

@chrisredfield3240 6 лет назад

Maybe cheaper just to fit a big bore kit and keep the rest stock.

@izrinzamirkamaruzzaman1099 6 лет назад

im curious of the A/F ratios/graphs for the 3 setups.mainly wondering if a full race exhaust will make the bike run lean...

@senicyrus7418 6 лет назад

@mariovaron7630 6 лет назад

Best chanel

@jospi2 6 лет назад

I've heard about the sound issue before, loud exhaust = power loss through sound waves.

@treycarter440 6 лет назад

Its not the sound waves that cause it. Its often due to back pressure and length. There is always some optimal configuration to make the most power at a certain RPM on any given motor setup. You play around with either the back pressure or the length, you shift the power around. Sometimes outside of where the motor does its best which is bad.

@chrisredfield3240 6 лет назад

There is a limit to how quite a bike is and still have full horsepower uses energy making it quite.
