    I was considering getting a slip on for my Ninja 400. But i dont like loud obnoxious sounding bikes. My bike isnt even brocken in yet so i havnt been revving it out. But today i went for a ride with my stock pipe. And started going into the higher rpms. And i decided i like the sound of the bike just the way it is. It has some nice tones to it. And i dont make people turn there heads from three blocks away because they hear me coming. I dont need the attension. And I like the ability to come home late at night without bothering all my neighbors. So today i decided to stick with the stock pipe. And when i got home i came across this video which made me feel good about my decision. I also wanted to say that i noticed someone in the comments saying to get a real bike. I also own a Ducati 939. And loved the little 400 Ninja so much that i bought one. Its a great around town bike. Plus sometimes its more fun to rev out a small bike then always holding back on a superfast bike. And on smaller canyon turns i can wip that little 400 around at faster speeds than my way more powerful 939.

    I live in Japan and have a 2020 Ninja 400 as well. My first mission was getting a new exhaust on for looks and sound. Got a Remus sports flow slip-on (illegal here) a few weeks after purchasing the bike and kept it on for a year and a half, taking it off for regular garage check-ups.
    I put on the original muffler back on for my last tune-up this past August and left it on...what a nice difference!! No lack of power, a tad heavier in curvies, but all in all, way better ride than having the little-noisy shitbox making my ears ring every night...Good video man!

    My fuel consumption on the 400 went up between 10-20% with the Leo Vince slip on. I leave it in a lower gear now with the rpms at 5-6k instead of 4-5k so that takes more fuel and I’m sure the lack of back pressure also contributes. Always a pleasure bro!

    I had a cheap Chinese exhaust for a while and it did sound pretty decent but it started to rust so I decided to upgrade to the Akrapovic carbon exhaust but before I did, I put the stock can on and I noticed few things as well. For one, I was getting much less vibrations! This was confirmed by my wife who rides pillion very often and she even suggested keeping it on because it made riding in the back a little bit more comfortable.
    I noticed I would speed more with the stock can because it was so quiet, I didn't notice I was going much faster than I though (80kmh in a 50 zone). With an aftermarket exhaust, you hear the tone change much more clearly and you get a sense of speed without having to look down at how fast I was going.
    Fuel consumption is much better with stock, for sure. I did a 300km (one-way) journey on the bike a year apart, originally with stock pipe and the second with an aftermarket exhaust. Basically travelled the same route in similar conditions (Summer in Japan) and stock was approx 20% more fuel efficient.
    So for me between the looks, the sound and the fuel economy, I would choose the stock can over the Chinese can but.. I would choose the Akrapovic slip-on over the rest. It looks good, sounds good and while fuel economy won't be as good as the stock, I'm sure it's better than the leaky Chinese can lol

      Louder pipe don't save lives, unless you know of a rigorous study I am unaware of. Louder usually just means incomplete combustion (and the resultant uptick in hydrocarbon pollution) , loss of power, angry neighbors, and traffic stops and tickets. Hearing you doesn't seem to get peoples attention.

    that’s not my real last name but it’s pretty damn close..I learned decades ago when I road race d 2 production motorcycles that the factory knows more than I do. I think I may have been the only racer that left the machine totally stock in the engine/air cleaner/exhaust department.
    I won 6 road racing championships, two time national champion with a totally stock running engine. To top it off, my racing weight was 190 pounds. I raced against guys that weighed as little as 140 on the same machine, and I had one or 2 miles an hour on them at top speed. I even left the stock air filter inside the stock airbox with the lid on the stock airbox.
    everyone I mean everyone else was experimenting putting aftermarket parts on their machines, making them slower. Louder but slower.. I was actually protested several times and had to prove that my engine had stock pistons and standard bore and stroke dimensions..
    because my machine was stock, I trusted it, I knew it was not going to seize or hole a piston or throw a rod , so I was able to learn how to actually ride fast by picking perfect lines, late brake, set up each corner so I would have the highest exit speed in the right gear at the right rpm so I could have a couple miles an hour extra speed all the way down each straight to the next corner and the next corner and the next corner. I learned how to maintain momentum, basically I learned how to ride and how to set the bike up by leaving the engine alone..
    The factory knows more than we do..

  • @smoke05s
    @smoke05s Рік тому +1

    The fuel mileage difference is there because you have picked up some midrange. It takes less of a throttle opening to produce the same power so you save gas. They guy below uses a lower gear for the same reason, in order to make the same power as before. Loud pipes alone do not save lives, it is a tool to skew the odds in your favor (you still have to be diligent) . . . but there are downsides and midrange reduction is one of the side effects (without a dyno tune to correct the fueling). 280 to 400km is very significant. To be fair the LV10 on the top end even with the fueling off probably makes more power than stock but who rides around at redline all the time (on the street)? . . . Don't answer that!

  • @sephkateno1037
    @sephkateno1037 3 роки тому +4

    If the ecu is running on stock digits then the best thing is the stock exhaust. Back pressure is always needed but it depends on the air filter too just a straight pipe with no silencer at all just opens up the exit you have to open up the intake too and modify the air to fuel ratio. My mivv gp pro exhaust has three silencers I never run it without at least one.

    I'm wondering if you tuned the bike when you put the after market can on (would have made a difference you'd notice and if you are turbo-charged, untuned could even cause oil leaks) and if you did, did you retune when the stock can went back on?
    A lot of folks forget an exhaust back pressure change can significantly affect the engine, mileage, power...

    • @smoke05s
      @smoke05s Рік тому

      Dyno tuning would make it run correctly but it is still debatable if he would still have lost midrange (fuel mileage) or not. Mileage is the best indicator for midrange because you ride where there is a speed limit. It takes a certain throttle opening to get up to speed. if that opening is less or you get up to speed faster so you are on the gas shorter it is the same. You have increased midrange. . . . Dyno tuning is so expensive for such a small HP gain almost no one does that on these bikes (for the street). If you have please chime in and let us know if your gas mileage on your typical ride went up or down after dyno tuning / a pipe and filter compared to stock.

    I mean your points are valid but did you tune your bike with the aftermarket exhaust? If you don't tune it after you change the exhaust it will not operate to its full capacity. Because it changes the air/fuel mixture.

    I bought cheap slip-ons for my last two bikes, and regretted it both times. Both times I decided to replace the cheaper ones with somewhat pricier products. I'm not talking about no-name brands, just the more economical products lines. Anyway, the second slip-ons were better sound and build quality, but I still regretted it due to the noise level. I left the DB killers in with both bikes, but I couldn't stand the noise on medium to long rides. I'm sure other people love it, but not for me. My next bike will think very carefully about what mods I'm going to do.

  • @joshuaspop8865
    @joshuaspop8865 2 роки тому +5

    A silencer in that slip-on probably would’ve made it perform similar to the stick can. Silencers are needed for back pressure.
    But yeah, stock is mostly fine. I will say an ECU flash is a very positive thing. The FTECU kit opens some restrictions and makes the bike run smoother and the engine runs MUCH cooler.
    Just buy the kit and do it yourself. It doesn’t change the fuel maps, so no time is needed.

My ninja 400 is a stock commuter so I've taken all your points for granted hahaha. Up shifts I rarely use the clutch (engine breaking wrist twist).

I have noticed that it gets a little hot in stop start traffic in summer but that's about all. I average 380kms at slightly faster highway speeds tucked, but sitting up at normal speeds it'll get the same distance (approx 3.8L/100kms). The one thing I changed was the mirrors; I got the ninja 300 mirrors as they're much lower and make it waaaaaay easier to lane split. Vis is ok still.
