We decided to see how these exhausts stacked up against each other in the horsepower and torque department. We used the same bike, on the same dyno, on the same day, and with similar conditions to ultimately bring you the most comprehensive exhaust comparison video for this motorcycle.
We compared the exhaust power gains from multiple brands such as Graves, Akrapovic, and M4.

The audio quality of clicking up and down gears from three different exhaust systems was amazing. If possible, would like to see more bikes featured like this as it’s some of the best exhaust comparison content out.
Thank you. We have been getting more requests for this type of video lately. We will do some more in the near future. Currently we are workinig on the GSX8S platform so a video like this with several exhausts will soon be made.
Absolutely agree. Never seen a video give such a good comparison of sound, look, appearance, and stats before
@@TSTindustries A decibel meter would be nice just so we can see a real comparison of the different exhaust loudness. You can get two meters, one for each camera, for around $40 total and it really would add some nice info for the videos with no real effort beyond turning the DB meter on.
Yes^^^
I’ve always love the low bassy rumble of M4 exhaust systems with the sharp pops while shifting nice and crispy sounds come from that M4 system
Akrapovic sound its insane
It's that engine....they all sound like that. My knock off Austin racing one sounds the same
give the audio engineer a raise for that intro
Great video, would love to see this series with a new set of 3 exhausts to test
This is a top notch, premium exhaust comparison video. Please do more of these for other bikes!!
Thanks! We try to do a video like this a couple times a year. It just depends on what other projects we have live.
-BR
Such great content! Thank you! I have a zx4rr that I totaled on the track and am having a graves low mount installed this winter along with full suspension. I’m going to have no excuse on the track this next season for being slow ;)
Maybe someday-I don’t have a go-pro or anything like that unfortunately
Perfect timing. Thanks for sharing
Graves block off plates & Version 2 velocity stacks would be nice addition to the graves exhaust. I have that entire setup on my 23" ZX6R and its sick!
That bike has our own blockoff plates and we are working on our velocity stacks.
I liked the sound of the Akrapovic the best, and I also like the look of it the most too.
They look the same with just a different sticker on em😂
Great video
Thanx alot for the informative video,such a good comparison between exhausts,the weight on the Graves is just ridiculous!! And the pricing too!!,all of them sound really nice tbh, but if I had this bike I wouldn't put the full system maybe just a slip on, the prices with gains aren't justifiable enough!!I'd put the money on the tune or getting other parts
you could say that about pretty much every exhaust. Put any 2 bikes side by side and the exhaust weight & power gain would be negligible outside of racing, especially on these smaller CC bikes where 5-10% more power in reality is a couple horsepower. For weight, most people would gain more by putting down the fork for 2 weeks and riding on an empty stomach.
Have you guys had a leaking issue on the stock oil cap? My wife’s ZX4RR has the oil cap hole shaved in such a way it’s not flat where the o ring sits between the metal and the cap itself.
Peep the GP shift, too! No flash required from what I've seen.
Thnx for the update
you welcome
Fantastic visuals and audio! Now that’s how to make an exhaust video!! Congrats! Please do aprilia RSV4 or Tuono! 🙏🏻
Great bike, I am sold on Graves, the quality is at the very top😎
Madonna santa, what a symphony! 🎵🎶🎼👨🎤
freaking love my zx4rr
Looking to get my first bike, would you recommend it?
i love my taotao beach cruiser
@@ryanwarkentin4706 Not at all. Not because it's too much bike or anything, but it's too expensive for your first bike. Get something you won't mind dropping. I'd actually recommend an older ninja 400 over this for a first bike.
@@ryanwarkentin4706it’s my first bike, yeah it’s more expensive then and regular ninja 400. But it has two more cylinders and sounds incredible. You get the perks of sounding like a true super sport without the actual speed. And when you’re ready you could always tune with a full exhaust and start get even more fun out of it.
The goat himself @tsharabi4
Hi Sir,mqy i know front tyres & rear tyres Size tksQ
qual o nome da musica que colocaram entre as trocas dos escapamentos ?
I love my 23ZX-4RR Look forward to getting the ECU flashed.
That is one of the most fun bikes in our stable at the moment.
i'd go with GRAVES because they actually develop/race the kawasakis and the quality on all GRAVES products is top knotch!
it's also the lightest.. i do realize it's the most expensive though
Not everyone will be willing to spend the extra money, but those who do will be getting a primo product. I do like the Graves best myself.
-BR
Akrapovic has the best low rpm sound but in higher rpm the sound is unbearable , so the fight goes betwin Graves and M4, with Graves winning slightly in gear changes sound !!
So ....... what were the results?? What extra power did you get over the stock 74hp??
Damn feels best daily driver
Great Video! Question... where can one get that same exhaust hanger? Did not see on your site.
That's a Graves hanger. Comes with the Graves exhaust.
@lnromandude just with full exhaust? I ordered slip-on, and did not get one.
@@jamespreacherbeck4306 yeah I think just with the full system.
Please try the Arrow Pro exhaust it we'll be so good ❤
What's the best performance air filter that you would recommend for tuning that inproves air flower and maintains filtration from your testing on the Kawasaki ZX-4RR?
MWR Performance. Great filter that does not have to be cleaned as often as others.
DNA has the best filters!!
N95 air filters
This might sound crazy, but does anyone make a header and link pipe that fits with the original muffler? Essentially a de-catted stock system?
yes its stock officer ?
We havent seen anything like that yet. If someone comes out with that it will require cutting oe parts as the catalyst can is part of the header system
Yes, I can help you with exactly that
Really like these wish they were on an aluminum frame and didn't cost what they do for the money might as well get a zx6
is my zx6r an aluminum frame
@@blizzthebike yes
You definitely don't buy a ZX4 to go as fast as possible for the money. You get this thing to achieve sick revs and noise at more realistic speeds. For maximum speed value, a used ~10yr old literbike will always dominate.
I guarantee you the 4RR will be more fun to ride. You've heard it a million times because it's true; it's more fun to ride a slow bike fast than to ride a fast bike slow.
How does the smaller header on the Akra affect the power comparatively to a proper sized header
Please look at the results in the video.
Same exhaust for zx25 and zx4 says it on the site now
Graves exhasut is insane
M4🔥😍
İts perfect sound
Short slip ons?
I thought the Graves sounded slightly better, but does that warrant the extra money? I’m not too sure!!
How he's shifting gears without using clutch? Please tell me!
This bike comes with a quick shifter stock. -TST
That gp shift comes as standard or mods?
You flip the lever at the end of the linkage and it's in gp mode. At that point your qs/blip sensors are reversed. Our flash tune service is available with a sensor software flip configuration. You can also rewire the sensor to flip its function if you are comfortable with wiring.
-BR
Awesome, it runs as a 2 stroke
Dreem Hounds music again 👍👌
Would be very interesting if some decent weight savings can be found.
Older in-line 4 400cc bikes are at least 10-20kg lighter with a proper aluminium twin spar frame
Yes, I was disappointed that it has a steel frame and not a proper aluminum spar frame structure especially given the price.
Music please?!
El M4 sin duda me gusta mucho más su sonido
me too
All down? Does it come that way stock?
No. That is called GP shift, and it's the reverse pattern. One up and the rest down. You have to flip the linkage lever arm, and reprogram the sensor inputs in the ECU during a flash. We can do that during flashing your ECU if you are using our flashing service, but you still have to flip your linkage.
@@TSTindustries thats awesome!! Thanks for the information!
@@ryananderson1854 no problem. Cheers!
is that rear sprocket oddly big? (not a mechanic)
The bike comes with a 48 from the factory. That was one of our prototypes in size 50, which is useful for one of our local tracks that is a bit twisty and tight. The 50 tooth size is not uncommon on these bikes.
-BR
I'd take acrapa, notes nice but a 4 into 1 with flat can like a kerker will sound clean and mean .cheers Bart
cheers bart
I wish the stock exhaust were on that same graph for comparison.
If you're interested in stock numbers, you can watch our first dyno run video with this bike: ua-cam.com/video/yvgsdDZM46Y/v-deo.html
@@TSTindustries Thank you. I love that bike but I'm afraid I'd kill myself on it. 😁
Everyone would believe that's a ZX10r if he dont do the top speed
Not if they look at the back tire haha
❤
💘💞
Graves 🥰🥰🥰
So is there a 90hp bike somewhere in this bike?
I believe a peak figure around 90 may be possible but that would require building up the motor quite a bit, internal friction reduction treatments, and running on race gas that provides more energy per conbustion (such as MR12)
Do you guys offer a crackle and pop tune on the zx4rr?
We do not. Our tunes focus on performance and practicality. Crackle and pop is outside of the realm of performance and practicality. I will add that this bike has quite a bit of valve overlap, and I wouldnt purposely tune a bike to have small explosions going on in the exhaust tract as the bike is expecting to use exhaust gas pressure fronts for scavenging at the exhaust/intake cycles crossover
What's up everybody this is Chris Moore!
Not even 1% hp diff, I guess it's almost within dyno error
Looks - Akrapovic
Sound - Graves
Too Loud - M4
I wish Graves went back to their shorter cans. Their older ones looked like the Akra does. That long ass old school can is lame. It sounds fantastic though.
How much power did it make stock?
You can see that in the dyno charts provided in the product page of our flash tune service here tstindustries.com/tst-worx-performance-ecu-tune-kawasaki-ninja-zx-4rr-2023.html

What’s. The top speed on that. Mike. With. Flashing and. New. Exsaust
I can tell you that after we race it in Daytona later this month. For now the top speed we have is on the dyno and that does not take into account drag and rider load.
these. aren't. sentences.
My wife is begging for this bike lol....😒 thanks kawasaki...thanks
She could be pressuring you to buy pointless jewelry but instead she wants a bike.... thats a keeper right there
@@TSTindustries into shop we go my man🫡
@@TSTindustries true!
think i like the graves the best
diferença totalmente desprezivel
Such a tiny difference. It makes absolutely no sense to pick an exhaust based on the performance here. I would just go for looks and sound.
motogp the shifter; so cool
This bike is destined to become one of our race bikes so the shifter had to be flipped.
is he downshifting? someone respectfully educate me.
You can change the orientation of the shift lever to where you up-shift by clicking down and vise versa.
i have a doubt. As the video shows, it can give arround 77hp but why in other videos,, this bike at full stock gives only arround 56hp?
Because this bike is tuned.
THANKS@@TSTindustries
Pushing down on the gear lever to go up threw the gears 🫤 am I seeing that right 🧐
@@BARRIEAM22 that is a reverse shift pattern commonly called gp shift. Its arranged that way to eanable easy upshifts mid corner without the need to upset chassis by shifting rider weight around.
That’s put me clean off getting one now 🫤
Is it decat?
Full racing exhausts do not have a catalyst canister.
it's decaf bro

Si senor
Why does it look like he's downshifting?
Reverse shift pattern for track applications
@@TSTindustries Ah.
it's called countershifting, you know like counter steering? To counter shift south of the equator, motorcycles have to downshift in order to upshift, but only at higher speeds, exactly similar to counter steering.
@@nickn7939 Like brake-throttling! Of course.
🤔
why the face?
Hữu Tào
I blew the motor on mine. 😅 it’s getting replaced under warranty. No tune or mods. Free ❄️ winter storage 😅
Edit: man these exhausts sound amazing 🤩
i fucking wish my 650 with the yoshi sounded that good.... dont get me wrong its awsome but i need to get an 4 cylinder XD
This little 400 is a little dragon isn't it?
Ko exhaust all day $100 😂🎉😂
For me akrapovic is really good
oh yeah?
Too expensive for full exhaust for most people.
no difference in exhaust muffler and sound comparing ninja 1000cc or 400cc, unbelievable!! They sound exactly the same, that 400cc is a big bargain!
not really for 2k more you can get a zx6r which make 130hp to this ones 80ish
Its the kind of bike thats fun for a while but then you realize its slow af. 😅
So what made you click on the video idiot. Lames like you know the content before clicking but still choose to click and say pointless sh!t. Lame a$$
yeah i don't get why everyone in the comments is saying it is amazing. I got my zx6r for 2k more than this and it puts down 120whp when tuned.
@@nickn7939 90% of riders are using less than 50% of a 600's potential 90% of the time. It's simply more fun maxing out these 400cc bikes.
I’m always bias to Akro 🤷♂️
Come on man!!
(Biden voice)
Is there any oil in that bike??🤣
Nah, we like to fill our bikes with peanut butter.
@@TSTindustries don’t see it in the glass tho🤣
you can't even see the glass clearly in any shots, also the bike would have blown up 🤣🤣🤣😄😃😆😅😂
@@nickn7939 1.09😉
This bike seems really overpriced for what it is. Idk who its really for
12 yo who don't even have a clue. I would honestly rather have the zx25r, it is more novelty than this one. Has a higher rev limit, cheaper, and sounds cooler. For power they have zx6r and zx10r, idk why we need a 4 as well when it is priced so high. It has to compete with an R7 and the R7 has more torque, and they even make a turbo kit for an r7 if you want more power.
This is because the normal motorcycle license in Japan is up to 400cc.
ZX4R is a motorcycle for the Japanese market
Track guys
I mean more cylinders means more crap to make
@@DorDor400 exactly, track guys love the 400. I currently have an R3 for track and waiting to find a used Zx4r to upgrade my track toy.
new a play toy.
Yes...toys are important for happiness ;)
you're a new a play toy
It’s funny when people are trying to get more power out of this bike. The whole point is a less powerful inline 4. That’s literally the whole point. A slow bike that turns 16k rpms and sounds great. I like the bike a lot but who cares about power on a bike like this.
Haven't you seen people buyinng a 3500 dollar Grom and then dumping in 6000 dollars into it to make it a high performance mini? It's inevitable. I can tell you for sure that your view is in the minority.
@@TSTindustries lol I knew there would be a snotty comment coming from you guys. Ya Groms are fun too and dumping 6k into a Grom is also dumb
@@19hundoc47 it’s not a snotty comment, it’s reality. Just because you may think it’s pointless or dumb doesn’t mean it doesn’t happen. Ride your own ride and enjoy it.
@@TSTindustries just ignore him, he's the guy who revv Tesla in the tunnel
lmao@@titaniopotenza5163
How to kill a bike without moving an inch..
Race teams and tuning shops must be graveyards for bikes if that’s the case. 🙄 -ML
