*Note: This AT2 muffler comes with a carbon fiber heat shield (not shown). Also sound insert is installed in this video, but is sold separately.
The new Kawasaki ZX-4RR sport bike is one special machine. Engineers at Kawasaki set out to develop a 400cc inline four cylinder engine built for high performance, and they delivered.
For this special machine we used our AT2 muffler to develop a Street Series slip-on giving power to the 16,000 + RPM's of the new Kawasaki powerplant. The AT2 came through in performance, sound, and weight savings. HP was bumped up by an increase of 3% and torque was bumped up as well, adding 4.3%. Our mission of adding power and torque throughout the entire spectrum was accomplished.
The sound of this inline four at 16,000 rpms with our AT2 is simply something that must be experienced in real life. True music! Finally, the styling of the AT2 can't be beat. It's now iconic matte carbon fiber end cap and heat shield compliment the lines of the ZX-4RR to perfection.
And that’s just a slip on lmao imagine what a full system sounds like 🤯
oh yeah believe that. full systems sing.
@@NudaMan turns out full system doesnt make too big of a difference due to the cat being so small
Rode with a guy on a track day with one of these and the Yosh pipe. Sounded absolutely wonderful even with DB killer installed. As usual Yoshimura is 👌
Is the db killer removable?
These smaller engine 4-cyl's sound fantastic
This inline 4 is VERY fun!
sounds like a freakin F1 car
eargasm, even stock exhaust sounds so good
Holy Shizzz!!!! That 4RR sounds WICKED!!! Well done Yosh!!
I've had it on my zx4rr for a few months now, it sounds soooooo good. great job yoshi and kawi
When Kawasaki can easily make a 400cc inline 4 but Yamaha can't figure out how to make a 900cc inline 4.
Kawasaki understood the assignment.
That’s freaking awesome 😍😍
I recently bought ZX4RR a month back, am afraid Yoshimura AT2 will be too loud here, often might get caught by police challans 😒
Is there any option to lower its sound further ? Or is it wise to consider Arrow Indy Race EVO slip on over this ?
It's only wise to use Yoshimura AT2!
@@YoshimuraUSA Okay, Cheers
yep im buying this exhaust
I am excited, to ride my Kawa ZX-4 RR when I'm back from business trip tomorrow 😍😍😍
sound so sweet
This sound look like F1 🔥
0:45 Crispy 👌
Amazing zound Muffler
Excelente sonidooooo !!
My god this engine is heaven!
I bought this so fast!
00:50 Legendary
If that is the zx4rr, imagine the new zx6r🔥
lol, nothing change
imo zx4rr > zx6r
You guys really need more EU compliant exhausts I would really love to buy some of your stuff but 99% of your slip ons are unavailable
🤯🤯🤯
Is it a 3/4 exhaust which eliminated cat or just an end can
Cat is still intact. This is just a slip-on.
Does it have Euro 5? if yes gonna order right now haha
No euro 5
@@YoshimuraUSA :(
@@MotorbikeLife519 sorry!
Yoshimura Comes with dp killer
If then I would buy
Sold separately.
❤
Do you have any videos of this exhaust with the db killer installed?
@@YoshimuraUSA You replied to a different message saying that the dB killer insert is fitted in this video.
There is a dB killer installed n this video, but it is sold separately.
@@YoshimuraUSA Where can you buy the dB killer from? I can't find it anywhere (UK)
@@amococ2487 Try performance parts they carry our product in the UK. Or you can order from our website.
Is this street legal in Europe?
We don't homologate for Europe. :(
@@YoshimuraUSA but.. you sell it for Europe right?.. for track use purpose off course...
Is the Hepta Force full system coming for zx4rr? Zx25r version is not sufficient due to low tolerance of oil filter etc
A full system is being developed for this bike in Japan. Stay tuned!
does it come with a db killer? if not which one to use? thx
Yes it comes with a sound insert installed. Its used in this video.
@@YoshimuraUSAJesus... That sound is with db killer? Holy Christ!
Is It with db killer installed? Sorry I didn't understand
Yes this video HAS the sound insert installed.
Is it legal for Italian rules for street use?
@@TheGianpy86 we don't homologate for Italy
@@YoshimuraUSA that's pity!
Just outnof curiosity, is there alpha T full exhaust system for 2024 zx-6R?? I’m waiting for my 2024 zx-6r for next season and thinking of getting Yoshimura exhaust if you have it.
As of now we don't have plans to make a full system for the ZX-6, we will have one soon for the ZX-4RR.
I have a 2022 kx250 do you think the rs12 full system would be quiter or louder than stock with the sound insert out?
louder, and you will loose mid to top end.
will there be a 3/4 system for this one?
We will be importing the new Yoshimura Japan system that is 400RR specific. It will be the go to system for this bike!
neat
Eargasm
Is that Euro 5 homologated?
No it is not
@@YoshimuraUSA shame 😪. So, I can't use it in European streets, true?
@@lucianozampa2296 depends on your local laws and regulations.
@@YoshimuraUSA Italy...
Can’t decide between this and a graves slip on. Someone give me some input! Thank you.
Go with us, you wont be disappointed!
do a sound test without the insert :DD
😍😍😍😍😍😍😍😍😍😍
Does this fit the 2024 Zx4rr as well?
We have not confirmed that fitment yet, but it should, its a brands new bike and they usually stay the same for 3-4 year cycle.
Dang! This is with db killer on!?
Yes.
@@YoshimuraUSA Jeez! It sounds amazing!
Aso necesito un full syste y si sale video genial
