Lmao exactly my thoughts 😂

Also needs a tune. Increased airflow n all. Does he know about air filters?

Who doesn't have all that just laying around? Peasants.

Cringe

He didn’t even respond lmao

Super cringe

totally agree!!! spot on!

you see he didn’t eliminate the CAT sort of the point of video

Glad it helped!

My thoughts exactly.

I don’t want it to loud” So I’ll put an LV-10 on it” 😂 Good video but I think you might be trolling us a bit. Ride Safe

How doesnt this have more likes???

I measured the length of replacement pipe right around 145mm

Zero.1 my friend doesn’t run a remap and he is fine, no noticeable power loss! Just an amazing sound

You will hear many opposing views on tune vs no tune. Its not that one is not right and the other is wrong, it just depends on your personal goals. If you are after best performance, than of course you will want an aftermarket tune. You really cant compare a bike with exhaust changes and no tune to a bike with mods and a tune, the difference is huge. If however, you are already satisfied with your current performance or your changes were minimal its not going to hurt the bike to run it with the stock tune. Hope that helps!

Superb you are. Thank you for replying. I was worried about engine issues later so thought of asking... I hope I won't have any engine issues with the current set up

Yes volume increase is noticeable but minimal (maybe 2-3db). It does increase power but not as much as full header would. My top recommendation to anyone wanting power and sound is headers. I really like my clone headers. Cheackout my “Akro Clone” video, I describe how to do the AIS blockoff which will prevent popping.

@@DirtGearTv I watched the clone akro video and after spending over $700 CAD on my slip-on I may try just the de-cat mod as I want to keep the cost down as much as I can. To be honest, after spending that much in the slip-on I was really disappointed with the sound. It is still a really quiet bike. I'm also less interested in power gains (it has good power) but the torque is fantastic. BTW I had to change the chain and sprockets recently so I knocked it down to 14 teeth on the front sprocket and went to a 520 chain.. the torque is nothing less than addictive. I would highly recommend doing this to anyone with a z900.

Yes unfortunately slip on alone doesn’t do much for these bikes in terms of sound or performance. I think you will be please with the sound improvement by deleting the CAT. Certainly for the cost of it it’s well worth doing 👍

Thanks Man! Technically you don't NEED a tune after even a full exhaust, but I like to do it. Taking out just the cat doesn't affect the AFR much at all on this bike. If you do the delete, checkout my video on 2wheel dyno works for your tune, they are great guys!

Ive owned a 2019 Z900 for 3 years now, I recommend it 100%. The accelerator is very smooth not jerky at all, there is engine braking but it is very minimal jerking. I daily drive it. It is a beast, oil change and go. I have 22k on it now. Your comment is 6 months old so if you got it, i hope you are enjoying it! Ride safe!!

Thanks! Its not absolutely necessary to re-tune with exhaust mods, but understand you may run into issues with it heating up a little quicker and decel popping

people says that this bike has bearbox problem..hard changin gears and fallout of gear a lot of times.. i like it more than mt09 but dobt sure about kawasaki reability

I’ve seen this mod and it does increase sound a bit. There are 3 system restrictions, cat, breadbox and muffler.

Thanks for the feedback! This is are a suitable option for some people. To play devils advocate, let me share why I didn't consider this option myself. For $200 you can get full "akro clone" headers which is proven performance. This video is just kind of an easy "free-bee" without going down the road of new exhaust. Notice how your bike now pop's during deceleration even after you've ridden awhile? That's a lean condition. The ECU is not programmed to compensate for changing/replacing up the exhaust, the narrow band o2 is very limited. That's an easy fix though, checkout 2wheeldynoworks!

@@DirtGearTv I don't think the "free bee" showed on your video is easy because it needs welding. I don't agree with you that you must remap the bike after changing the exhaust, because the ECU will compensate for that. However, this compensation is limited and you can get extra horse power by adding an air fuel optimizer like a Power Commander; but it will not hurt the bike if you don't add it. I myself will place an order for a performance air filter and a Power Commander V and will get it tuned at a Dyno Tuning, for added horsepower only. I really love the sound and looks of this Leo Vince Can, I'm just worried about water getting inside it since it is placed almost vertically.

Yeah it will run lean. The ECU won’t be able to make the adjustment. Bike ECU is not as advanced as car ECU.

@@nrsimhavallabha5128 hey man I know This is old but when you installed the mid pipe was there any backfiring on decel?

Yes, a little bit of backfire until I had the exhaust air injection disabled and plugged. I also had a power commander V installed, so no back fire at all on my bike.

It shouldn't come on, if it does, put some miles on it and will go away

I'm currently using the Harbor Freight 170a/240v wire feed setup for mig. Its a surprising good little welder. I use it with flux core and gmaw

Thanks and Yes, the sound was a pretty substantial improvement!

DirtGearTv ok thanks! Do you think a slip on exhaust would do the job for the sound or a full system will be better?

Honestly, removing the CAT did more for the sound than the slipon as well as power. One of the reasons I made this vid was because of my disappointment with a slipon only. Watch my video on the clone header system if you want the best budget option! Good luck

DirtGearTv ok thank you very much!

Both mufflers do a pretty good job of reducing db. Most of the sound increase comes from replacing the first muffler and the CAT. Very little sound difference just doing the slip on

Legend!

You should be fine without a tune, it’s deff not going to harm your bike but you’ll want to do the AIS block off to prevent decel popping. You should like the sound with a slip on and cat removal, not going to be loud but will have good growl to it

Thanks for quick reply. This is all I need n feel the same as you. Don’t want obnoxious loud I just want a lil more growl. Ya have link for ais?

Ok perfect 👌🏼 I would do a full tune n let them dyno if I had to buy, honestly just like I said I want a lil more growl is all. Not interested in changing the response because I love it ! If there is a link for Ais I’ll order now 👍🏼. Now it purrs nicely and neighborhood friendly but, they will survive! Lol. 30-40percent meaner and I’m good. I definitely don’t wanna lose my bottom half. Thanks in advance. I’m getting both arguments from my group but, the ones I trust are with me lol. Love em but, some friends have no clue. I check n check ✅

@@DirtGearTv 📍

@kaisersozee6541 did you end up removing the bread box?

Nahidul Haq It’s not absolutely necessary, however it’s a good idea to tune after exhaust changes are made

I believe this is the one: www.ebay.com/itm/113533165622 I think you'll be happy with this mod. Also as a followup, I'm currently working on another "mod" video that will accompany this very well. Will be a killer combo, so stay tuned!

I would

Yes, exhaust not being processed through a catalyst anymore

Nope

I do, but the bike has been changed at this point so the sound wouldn't match if I record the current setup, sry

Thank you! Will do

@@louieg5766 it was a compliment buddy, don’t get your panties in a wad. He looks very young in that Tee as compared to the shirt. That’s all I said. Relax.

It will be quite loud. Depending on the slip on. Mine is very loud. I bought it that way though. I would suggest listening to exhaust videos if they are available.

In my state (PA), bikes are not tested for emissions.

@@kirkleidemann5051 Cool. In my country, people sleep in beds.

In the vid I mention I ran the stock muffler for a while as it's unrestricted. In fact, I didn't end up keeping the Leo on this bike as it was a bit loud for my preference. I spent a couple dollars on the piece of pipe ($12 total I believe) but you're correct about using a mid pipe if you prefer to not have welded. Can also bring to local exhaust shop to weld up to save money.

And yet 2 strokes are in abundance in EU which produce 50x the hydrocarbon emissions

@@DirtGearTv abundance? where do u get your info from?

Sound like a woman

Back pressure isn’t a thing for making power or torque. Basically every bike makes more power bottom to top with a flash tune and opened up exhaust. Furthermore, just because you can’t ride your bike doesn’t mean the rest of us have that problem, the extra power is better to have and not need.

Why’s that?

Ramses19912 What story? All you did was simply repeat what I say to people in my videos. Checkout the video on 2WDW and why an aftermarket tune is important.

​@@DirtGearTv 1:10-1:45 yes you have to tune if you want to get the most out of it indeed. However, at 1:25 you state that you are going to lean out your mixture with a full exhaust system and that you have to throw more fuel at it (with a tune I assume you meant). This is not true as your ECU will automatically adjust the air/fuel ratio to whatever it has been set to in the ECU, it will not run leaner nor richer. On the practical side, you do need to account indeed that the bike will startup lean after an exhaust system/air filter upgrade and requires some time for the ECU to recover its air/fuel ratio. So in short, what I understand from what your saying is that you lean out your system by upgrading your exhaust system and that you need a tune to get the air/fuel ratio back on track (or better). What I’m saying is that it’s not necessary to tune your bike after such an upgrade as the air/fuel mixture will be restored by the bike it self over time (say 30mins?).

Ramses19912 It’s a common misconception that because a bike is fitted with a narrow band sensor the factory ecu performs the same functions as an advanced fuel management and wide band O2, in short it does not. Your factory narrowband sensor is not giving you an advanced reading of AFR it’s basically telling you it’s lean or rich and is very limited in its mixture adjustment. An aftermarket tune is a completely different, if it were the same thing dyno tuners wouldn’t be in business. So yes once you make any changes to exhaust you’re already outside the parameters your factory ECU will compensate for, this is why as soon as you change your exhaust the bike will pop on decel and we correct this by plugging the ais

DirtGearTv if the mixture adjustment is very limited then it wouldn’t make sense a tuner could fix that. The only thing a tuner does is adjusting the target AFR to what the wishes of the owner of the bike wants (more power/better fuel economy). It doesn’t make sense a control system is not capable of controlling its own system. A lambda sensor, doesn’t provide data about AFR, it provides data about emission particles as each AFR has its own composition of different emission particles like NOx and CO2, the ECU then translates this to an AFR and indeed concludes it is running lean or rich compared to the target AFR. But as we are speaking about a control system, which it clearly is, otherwise theres no need for that lambda sensor, it adjusts its AFR to converge to its steady state response. I own a z900 from 2018, when i took out the cat i had pops and bangs like you described, then went to a tuner because i wanted a smoother power curve and yet i still have my pops and bangs on decel. So if your theory was right this shouldn’t happen.

😆

I never said it would do more than an aftermarket system, I said it was cheap and easy free power

emissions laws are scams

@@ragimundvonwallat8961 really, weird how the ban of lead in fuels lead to lower lung cancer rates... must be a scam.

@@StarryNightSky587 rigth, it is

No different than putting on an aftermarket exhaust

This is one way to do it, definitely not what I would call "the right" way. Also you can buy a connector pipe for like $60 on ebay for this mod rather than turning the bike into a chopped up turd. So I agree with you in part, however the ECU will not correct this much of a change in exhaust, it was never designed to. If it didn't require a tune than why does it lean pop after the change is made?

I don’t delete comments for people who differ in opinion, I like feedback. De-catting a bike is more common than you may think. What’s the first aftermarket move people make when you buy a bike? Exhaust. So the overwhelming majority are already “decatting” in reality no one cares about it on the bikes except maybe California. It’s a bit of a stretch to call me paranoid though. I’m close with the dozen or so police officers who are also my neighbors, who I also rode bikes with. People don’t buy sport bikes to always stay under the posted speed limit, neither does anyone buying a car for that matter, so let’s get real here. Maybe you’ve never broken the speed limit, but for the %99.9999 rest of us, i’m just trying to be respectful towards my neighbors 😜

@@DirtGearTv well said. Much respect for you. Sorry for being so harsh in my post. I dont speed and the Z900 is plenty fast for me. Cheers.

Lame ass lmao

You did realize in the video I'm advocating for "opening" up the exhaust right?

CAT removal “non proven” good one 😂

I think you ought to understand the purpose of the catalytic converter before making that biased comments. Hint : it is used in industrial chimneys and wind turbines. So umm, research, maybe?

Hi you must be new here, welcome! Myself and the community here love to hear differing opinions, so maybe you'd care to expound on what's "wrong" and how you'd do it "right"? Easy to say others are wrong so please back it up with how specifically you would build it oh great one 🙌

Why's that? If true, i'm sure others would love to hear why you think... Don't be shy 🙈
