Yoshimura ALPHA-T Slip-On vs STOCK Exhaust Sound on 2018 Kawasaki Ninja 400

The Yoshimura ALPHA-T Slip-On Exhaust is a great choice for many Kawasaki owners out there. So we've decided to make a video showing off the overall sound and look of the Yoshimura ALPHA-T Slip-On Exhaust System on the 2018 Kawasaki Ninja 400.

YES! THIS is how you make an exhaust comparison video! NOICE!

[@darwinsinthavong8323]

Agreed !

[@dTheHammerb]

Loved the format you used to make this video. Basically perfect!

[@zh85]

$550 for a slip on is just not worth it for me.........But excellent comparison video.

[@paulhorvath9784]

I paid 1080 for my Yoshi Alpha T for 2019 Gsxs ..Costly but I virtually got it free seeing I got $1000 dollars of my brand new bike due to ordering prior to April 2019. They sounds 100 times better on 750's or Liter bikes and just with slip on and air filter you gain up to 5 Bhp that's before ECU Flash /Dyno..

[@superduperkid3143]

You guys are smart. I can't stand people who do exhaust comparisons in enclosed spaces.

[@JadenZeCreator]

Definitely just me, but does anyone else kind of like the sound of the stock exhaust better? Like it’s obviously not loud enough but I prefer the scream over the growl of the slip on

[@alimohammed4709]

washthebrain yess. Much preferred. Why would you want your sports buke to sound like a dirt bike

[@Mariely1]

Mmh true. I’m not sure if I want to spend 509 now

[@minhdangoz94]

Yep, that's HOW we make exhaust sound comparison ♥

[@turdferguson290]

Just had mine installed today...I sound like a madman!

[@DaBuGzLiFe]

The exhaust looks nice. I dont like the sound of the ninja 400 but damn the video was perfectly formatted. Bravo

[@theseeker4313]

Wow exactly what i was looking for, you did a great job with all in one loved it!!

[@FlesHBoX]

Would be awesome if you had a db meter to compare. I'm going to be getting my Z400 in a few weeks, and a slip on is one of the first things I think I want to do to it after the standard tail tidy/led conversion, but I really don't want a super loud exhaust (90 db or under preferably), I just want to get rid of that ugly stock can, and get some nice lower end to it. I think I prefer the sound of the Graves over the Yoshimura, but the Yoshimura does sound good.

[@justintorrez640]

Perfect comparison video thank you!

[@Skovsnegl]

Sounds alot like my Kawasaki Er-6F.. nice to hear :)

[@a1_digest501]

Got a $1000 now when is the toce exhaust coming for the ninja 400!!!???

[@TSTindustries]

We weren't given a launch date yet

[@a1_digest501]

TSTindustries approximately do you know when I need an exhaust if tonlong i have to go with the yoshi

[@goodtimes2656]

New one sounds like a card in the spokes. Id go back to stock. Also it is through my speakers. So it could sound better in person

[@TSTindustries]

I'm sure you would change your mind hearing it live.

[@JaySilva88]

The db killer totally kills the sound.

[@TSTindustries]

it does

[@dougalmanzar]

so is it true that top end is somewhat restricted and hence in need of an ECU flash to release top end power? And what about after adding a full exhaust to go with ECU flash? this bike would break 50 hp at the rear wheel ?

[@paulhorvath9784]

ECU Flash / Dyno tune is always recommended even on Stock motorcycles due to factory fuel lean factor to meet new Euro Emissions and fix mapping to help Throttle response,Smoothness and Economy..A good slip on and high flow air filter with a proper Tune will roughly result in Approximately %10 bhp gains and some Torque.

[@featzkbai]

such a sick muffler, bit too pricey tho for a bike I'm only keeping short-term

[@Clove_Parma]

very true, good for those that want this as their long-termer bike though (as few as that may be)

Prefect Video

[@pucixd_7114]

Nice video!!!

[@TSTindustries]

Thank you. It is great to have our effort appreciated.

[@cheguaromal]

TSTindustries, Can you please do a video on exhaust comparison with and without db killer of Alpha-T Slip-On for Ninja 400

[@TSTindustries]

We did. This video has footage of those two variations. With dB killer installed starts at 1:09 , no dB killer starts at 1:57.

[@alix6028]

db killer for City riding no db killer for Expressways

[@MrMotorMedia]

Hello! Good looking content you got there ;). Is it okay if I used it in an exhaust compilation? I will give you credit in the video ofc!

[@gavipincus6493]

How is the bass tone of this exhaust without the baffle in? I'm looking at this or one of the Arrow exhausts. Also how's the TOCE exhaust coming along?

[@TSTindustries]

Toce is still a ways out. We need to proof out a few more prototypes to make this new type of exhaust. The Yosh sounds really nice on this bike. With the dB killer in the sound takes on a slightly whistly sound. When the muffler is installed without the dB killer, the bass note is very nice, with a round and smooth character, until you reach 6000+ RPMs, and then it becomes a bit raspy. The rasp will be there with pretty much every exhaust.

[@tejaspadhye]

with the dbkiller it just soundsough, like engine is running without engine oil.

[@tagabukidmedia]

What is next? Clip-ons?

[@arty7542]

That would be the next sensible step! And then by the end of the year if we could get some shorter mirrors. That would give this bike the best look/sound. So stoked for this bike.

[@ThisTimeTheWorld]

Neat bikes but that noise they make would get old fast. It's good to see something that quiets the exhaust.

[@alexbartlett9396]

oh man that sounds fucking insane without the db killer!!!

[@bwolt5211]

I luv this sound ...can I fit it to my husqvarna vitpilen ?

[@TSTindustries]

At the moment we are not seeing any availability of a direct fit Yoshimura exhaust for that model

[@1down5ups]

I know this is the exhaust but i was wondering if you guys are in the process of making frame sliders? The Kawasaki price is ridiculous $310cad . Was looking for an aftermarket one

[@TSTindustries]

One of our engineers is busy with that project now.

[@1down5ups]

TSTindustries perfect. Thank you so much!

[@ForrestFarris]

Sorry TST but Moto911 has them for $90

[@paule5812]

Sounds awesome what tires are you guys using on the bike?

[@TSTindustries]

They are the stock Dunlop Sportmax GPR-300 tires.

[@OGKennyLee]

Do you currently have this in stock for the Ninja 400 2023?

[@TSTindustries]

Our website has live inventory tracking. If it shows available then it is in stock.

[@AyeItsXander]

Any pros and cons with having out? Besides the sound? Lol

[@zxc9884761]

Hi, what is the db level of this exhaust?

[@jj__757]

The Two Bros. slip-on sounds way better.

[@Dynamis_Kalon]

Indeed. and it costs much less as well, but I prefer the look of this over the Two Bros so I'm kind of conflicted.

[@jj__757]

Meretti, Mich & Mi I own the Two Bros. slip on. I love the look. The carbon fiber looks amazing.

[@berkedf9725]

Is the exhaust for the Kawasaki Ninja 400 legal in Germany?

[@TSTindustries]

We cannot confirm that

[@berkedf9725]

Does the exhaust meet the Euro 4 regulation? Or what emissions has the exhaust

[@motomirako]

Würde ich auch gerne wissen ...der akra ist zu leise ...welchen würdest du kaufen ?

[@chaosmakeryt6764]

Its so much louder irl "Yoshimura"

[@TSTindustries]

Yosh sounds real nice on this bike

[@chaosmakeryt6764]

@@TSTindustries we just got a 400 5 days ago

[@RaviKumar-uy8ss]

Which one is better between alpha t full exhaust or slip on?

[@TSTindustries]

You can't compare the two with a word like "better" because there are multiple things to consider. The full removes the entire OEM exhaust system and there are implications to that. You should probably read through the product pages we have for these items at TSTindustries.com

[@RaviKumar-uy8ss]

@@TSTindustries thanks a lot bro

[@TSTindustries]

No worries. Hope you find what you are looking for. Next week we will have the Graves exhaust lineup for this bike as well.

nice video, but!! the stock exhaust sounds much better.

[@KopperWoT]

What diameter slip on for the 400?

[@TSTindustries]

The outlet of the header where the slipon mounts is roughly 1.75"

[@hardpipe8569]

TSTindustries i would like to ask which or what type of slip on exhaust sound are good/best for KAWASAKI 400, is it yushimora, akrapovic, m4, or SC..?

[@TSTindustries]

We can't tell you yet because all we have experience with so far is the Yoshimura slipon, and some Toce prototypes.

[@TSTindustries]

besides, my answer would be subjective and not necessarily what you would consider "best sound"

[@hardpipe8569]

TSTindustries thank you so much

It is a full system¿

The slipon exhaust is legal for street use.

[@htcdesire3153]

@@TSTindustries is it legal without the dB killer too? Or does sound have nothing to do with it or is it just emissions?

[@TSTindustries]

@@htcdesire3153 The dB killer is included with the exhaust. The homologation for street use is achieved with the dB killer in place. In our dyno tests the small bikes actually have a slightly higher output using exhausts with dB killer installed, so you may consider having that piece in there.
