Best exhaust for Kawasaki Ninja 300

Most Ninja’s stock exhausts are both inefficient and nearly always sound like a higher pitch pur that just doesn’t match the tenacity of a high speed street bike that Kawasaki offers, because of this we’ve compiled the best exhausts for the Ninja 300.

We tested a variety of exhausts on a variety of factors from build quality, sound, longevity, price, brand trustworthiness and much more. We found the best slip on exhaust for the NInja 300 was the LeoVince LV-10, we also found the best full system exhaust for the Ninja 300 to be Akrapoic’s racing exhaust system.

Why you can trust this review, is that at Bikes Future we take immense pride in writing top quality informational articles and buying guides, we consider many different factors including personal experiences with the parts we recommend.

One thing to note when choosing a new exhaust for your Ninja 300, double check fitment and specifications. There’s a variety of variations of the Kawasaki Ninja 300 and it is easy for them to be mixed up, especially when choosing a motorcycle exhaust.

Should you choose a full system or slip on exhaust for your Ninja 300?

Full system or a slip on exhaust? It’s the first question you’re going to ask yourself, what will be better for my Ninja? There are pros and cons to both full systems and slip ons, and it will come down to the rider’s personal preference. 

A full system exhaust is going to maximise performance, cut weight and also improve fuel efficiency. Out of all the parts and accessories you can purchase for your motorcycle, a full system exhaust will provide the most value for money. The part that will provide the second most value for money is a slip on exhaust. There are benefits to both of these but the full system will simply maximise the benefits a high quality exhaust can bring. 

The problem with a full system exhaust is it’s going to be a lot more expensive and it can be difficult for some riders to install. It needs to be installed properly, there’s no if’s or but’s. What you can do is bring a full system to a mechanic and have them install it for you instead. This wouldn’t take a mechanic long and shouldn’t cost you much either. 

On the other hand, a slip on exhaust will drop some weight, bring performance benefits and potentially improved fuel efficiency, but not to the same extent as a full system. Although a slip is going to be significantly cheaper, even a novice rider will be able to install it for their Ninja 300.

What if I want a full system exhaust but I can’t afford it?

Luckily you can actually purchase a slip on exhaust, and then later down the track when you have some cash to spare, purchase the internal piping for your motorcycle, install the pipes and then reattach the slip on exhaust you were previously using. 

You might not have noticed but a lot of the time the difference between a manufacturers full system and slip on exhaust is that the slip on is just directly attached to the piping. Because of this you can always purchase the slip only, and purchase pipes later down the track, although you might need the help of a mechanic depending on the complexity of the installation.

Best slip-on exhausts for the Kawasaki Ninja 300

Yoshimura R77 Slip-On Exhaust

#1 Best slip on exhaust for the Ninja 300 

Yoshimura is one of the most well known exhaust manufacturers, taking the advice and knowledge from their professional racing team, their exhausts are built from practicality and first hand knowledge of what a racing exhaust should be.

If you hadn’t known, Yoshimura actually has a professional racing team, why this matters to you is because they use the opinions and advice from their racers when designing and producing their exhausts. This translated into some of the best exhausts on the market, and especially for those interested in racing and maximising high speeds.  

The R77 is designed more for casual motorcyclists while still maintaining all the benefits and designs of a racing exhaust. It’s built mostly from stainless steel but the end cap is carbon fibre. This creates the perfect middle ground between durability and weight reduction. Most riders avoid carbon fibre because it’s more expensive but even worse if you have a slight crash or just drop your motorcycle there’s going to be a good chance you’ll need to replace that carbon fibre exhaust entirely. 

One thing to note is if an exhaust leans either to torque or high speeds it’s going to come at the cost of one or the other, the R77 is a racing exhaust that improves top speeds, which means it will come at the cost of your motorcycle’s torque, although it will still be far better than stock exhaust at the end of the day. 

The R77 is going to squeeze extra performance at top speeds and allow your bike to reach higher revs, it achieves this because it’s a lot lighter than a stock exhaust, secondly it uses a high flow trapezoidal design, in layman’s terms it means maximising high speeds which is perfect for anyone riding a Ninja 300. 

The R77 is bike specific, so if you’re riding a NInja 300 you shouldn’t have a problem, although still double check on Revzilla’s ‘fitment’ option, that it will properly fit your motorcycle. If it does fit your bike, installation won’t require any special knowledge, it actually uses a bolt on installation system which is super simple that even a novice rider will understand. 

Yoshimura has been in this business long enough to understand that for their consumer exhaustion, sound is an important selling point. The R77 is no pushover, it’s not excessively loud but at a nice sweet spot where everyone on the road is going to be aware of you, the sound itself has a deep putter which seems natural for the NInja. 

This is our #1 recommendation for the best Kawasaki Ninja 300 exhausts, so it is above the affordable range but it comes with a long list of benefits. We couldn’t not recommend it, but we’ve made it so to provide more affordable options below so keep reading.

LeoVince LV-10 Slip-On Exhaust

Best affordable exhaust for the Ninja 300

We won’t lie, we’ve recommended LeoVince’s LV-10 slip on exhausts in countless articles because they’re one of our favorite choices for an all round the best exhausts in the affordable price range. It’s not cheap but it also won’t break the bank, it’s in that niche range of affordability where you’ll get the most bang for your buck. 

The second motorcycle I owned was a Ninja 300 second hand white 2014 model, it was a beauty. I replaced it’s banged up stock exhaust with a leoVince LV-10and back then I had little complaints  and all this time later not a lot has changed. 

It’s a well built exhaust that sounds great and also cuts a lot of excess weight due it being made from stainless steel. This exhaust is only 4.6 pounds, that’s pretty damn light for an exhaust. If you manage to install aftermarket piping down the track you’ll shed heap of weight off your NInja 300. 

LeoVince has predominantly produced exhausts for racing and sports bikes, we’ve always found that manufacturers that specialise in a certain area of motorcycling tend to learn the subtleties of their area of choice. LeoVince has chosen stainless steel which is perfect for most street riders, why? 

Because stainless steel is lightweight but also very durable. Now it’s not going to be as lightweight as carbon fibre, but it will be a lot stronger. It won’t be as strong as titanium but it is going to be lighter. Stainless steel is the perfect middle grand for street motorcycles such as the Ninja 300. 

Lastly we’ll talk about some of the power benefits the LV-10 provides, you’ll notice it’s a compact exhaust which means it’s shorter than most slip ons and the diameter of the pipe is smaller as well, this is ideal for street bikes and city riders because the sizing of this pipes will have a big impact on torque and how quickly you can get those revs up from standstill.  

Most city riders or those riding street bikes, unless on the track. Aren’t going to reach top speeds and maximise rpm. That’s why we decided to go with an exhaust that leans more heavy on torque then higher speed. 

Now lastly let’s talk about the sound of this puppy, it’s pretty decent. To be frank it won’t compare to a full system exhaust although it still comes along with a nice deep purr.


  • Stainless steel build
  • 4.6 pounds
  • Sandblasted end cap
  • Matte black
  • Laser cut bracket
  • Affordable 
  • Light weight
  • Trusted brand
  • Compact dimensions
  • Very strong levels of torque
  • Specifically designed for sport bikes
  • Simple installation
  • Great aesthetic
  • Deep sounding purr


  • Favours torque but at the cost of higher rpm
  • Some riders dislike the look of the compact design

Motorcycle Slip on Exhaust system With Muffler

Best cheap exhaust for the Ninja 300

When I first got into motorcycles I was young and like most people strapped for cash,  so I understand that many motorcyclists, especially the younger generation, can’t dish out huge bucks on a brand new exhaust. 

Here, our recommendation for a super cheap option which isn’t actually as bad as you might think, now this is a no brand exhaust off Amazon and we haven’t personally used it but I have friends who have it installed and say it’s a good exhaust for how cheap it is. 

We don’t recommend purchasing exhausts off a general store such as Amazon, because what’s for sale is mostly cheaply made that have poor longevity and could break on your mid ride. 

This exhaust is produced from Ransoto, it’s the best exhaust for the Ninja 300 at this price point although I’m not so familiar with the manufacture. Since it’s a cheaper option it’s a mixture of aluminium and stainless steel which is expected at this price point. 

Something that stuck out to us about this exhaust is people we know purchased it say it’s decent but more importantly it’s managed to accumulate a heap of customer reviews which are all overwhelmingly positive. 

In terms of the sound of this exhaust, we had a listen based on a few different video’s and we would say it’s alright, at this price point it’s impossible to find an exhaust with a deep roar or purr that will match more expensive options, so you’ll have to make do unless you’re willing to spend more if sound of an exhaust is important to you. 

In terms of performance benefits it’s hard to say, I mean this exhaust isn’t coming from a prominent racing company and there’s been no rock solid testing so it’s arguable, it is significantly lighter than the stock exhausts most Ninja’s come with, which will obviously translate into performance benefits, but by how much? We really don’t know.  

Overall, Ransoto offers a respectable budget exhaust and they deserve some credit for creating something of quality at such a cheap price point, now how long it will last is unknown but customer reviews are very positive so we would assume it comes with some decent longevity.


  • Made from aluminum and stainless steel
  • 6 monthly warranty
  • Removable baffle
  • Compatible with all variations of the NInja 300
  • Cheap option
  • Decent aesthetic
  • Overwhelmingly positive customer reviews
  • Lighter than stock exhaust
  • Easy installation
  • Adjustable sound
  • Comes with curved pipe
  • Great aesthetic 


  • Questionable quality
  • Unknown brand
  • Lacks instructions

LeoVince GP Corsa Exhaust System

#1 best full system exhaust for the Ninja 300

As we explained before a full system exhaust for your Ninja 300 is going to maximise a variety of performance factors and is without a doubt the most value you can get from a single motorcycle part. Remember that full system exhausts are quite pricey and when it comes to the internal systems of your motorcycle it’s not something you’ll be wanting to skimp out on. 

We felt LeoVince’s GP Corsa hit the sweet spot for the best full system exhaust for a Ninja 300, and the best thing is that it’s actually an affordable full system exhaust. We generally don’t recommend full system exhausts because they’re crazy expensive. LeoVince has done a great job at providing a full system that brings with it a bucket load of improvements and still staying relatively affordable. 

We’ll start of with sound, this exhaust is really loud and while we loved the sound if you’re riding for long hours it can get on your nerves, luckily you can adjust the sound, and we found without the baffle it was a little too loud, but with the baffle installed it was completely fine. It’s got a very deep roar and the level of decibels is quite high. There’s no doubt in my mind everyone on the road is going to know you’re coming with the GP Corsa installed, it’s definitely ideal for city riding when zipping through tight lanes and busy traffic. 

Where this exhaust excels is performance, what we love about full system exhausts is that they ditch tons of excess weight when switching from stock. This in itself will improve your Ninja 300’s top speeds as well as torque, The GP Corsa is a mixture of stainless steel and carbon fibre, it’s going to be durable but also light weight. A friend came off his bike with the Corsa installed, it was a mild crash but the exhaust held up and didn’t need to be replaced. 

Unless you’re looking for an exhaust specifically for racing, the GP Corsa is perfect for all types of riders combining durability and a nice level of weight reduction. 

For performance benefits, we’ll be assuming you’re replacing a stock exhaust system, in this case you’ll see power improvements across the board, we were not particularly sure if the Corsa leans more on torque or top speeds. But the ride felt smoother and we noticed significantly higher RPM and it being faster off the mark, although you can argue these benefits are from the reduced weight.

  • Heat resistant fiberglass
  • Produced using stainless steel
  • Round design
  • Bolt on install

  • High quality stainless steel
  • Guaranteed longevity
  • Exhaust gas flow

  • Works with stock fuel settings
  • Improves all levels of engine performance
  • Nice aesthetic
  • Awesome sounding
