Kawasaki Z900 Mid-Pipe Install / "Bread Box" Delete - With DECIBEL TESTS!

Thanks for showing every step of the process with hard data to back up your results, best breadbox delete tutorial on yt by a long mile. The effort you put into your videos is noticeable and appreciated, thank you, subbed.

[@MotoMedic]

I really appreciate that! Thank you!

[@Soul_Survivor2]

Awesome, like how you tested especially before putting on the muffler. Thanks for a very useful video

[@MotoMedic]

Thanks for the comment!

[@rav007]

did you notice the issue on the inside of the pipe, on the flare out section? at least the way they manufactured mine, the smaller pipe was pushed into the flared section creating a lip/pocket for the airflow to catch on. i had to use a special cutoff wheel on the inside to remove the excess and taper it so the transition was smooth.

[@zsolt.fazekas]

Nice job! I just would like to warn everyone that this link pipe won't fit to newer models for sure! The muffler's/slip on's end is different! In case of newer models (2022-2023) the pipe of the slip on goes into the bread box, however, in case of older bikes it's vica versa: the end pipe of the bread box goes into the slip on's end. Be careful at purchasing!

[@Raz_bu]

Bro do you know where u can get for model 2023?

[@zsolt.fazekas]

@@Raz_bu I think, there is no 2023 (EU) model specific. If you buy this one, you definitely need to weld, unfortunately.

Hi, I delete the bread box today. Sounds great with stock exhaust. I noticed the engine takes longer to cool down and maybe it's my connection but I can feel little air coming out of joint where the mid pipe links. Do you have any suggestion?

[@MotoMedic]

Depending on the mid pipe you bought it really doesn't have a gasket so you just have to make sure the clamp is tight and the pipe is a straight in the clamp as possible. I don't think the bike would actually take longer to cool since there's less there to hold onto heat when removing the bread-box. Weird.

[@savi0ursden518]

Thanks for the video sir! What other changes do you suggest when getting a bread box delete in z900 2023? Do I need to get my air filter changed or can i still run with the stock one? kindly suggest

[@MotoMedic]

If you're doing this you won't need a different air filter or specific tune. If you wanted to get the ECU flashed that can get the best performance out of the bike in any case.

[@gabrielleherrera3411]

You don’t need to remove the whole thing, just removed the cover and start cutting after the welded spot per instructions, the blade can go through w/ o hitting the oil pan like the z900rs

[@MotoMedic]

I am one of those crazy people that prefers to do something right rather than half ass. It took an extra 30 minutes to remove it and cut it on my bench.

[@johnzamora582]

New subscriber here! Awesome video! I have a 2024 Z900 will this fit on my bike and if so what are my options for slip on exhaust that will fit on this mid link pipe? Thank you!

[@MotoMedic]

Should fit. Any slip on that would go onto the bike stock should work with this. I'm using a Leo Vince slip on

[@marcjohnson7734]

A cleaner look and a 4kg weight saving at the very least, get a decent slip on and fkn boom

[@MotoMedic]

Probably the plan

[@infojn-um8jm]

Thank you for your reply. I rode the bike, and when I reduced speed and slowed down in the 1st gear, if you were stopping..it made a popping sound. It sounded cool, but does your bike do the same? Also, I noticed some heat from the engine. I got my mi-pipe from ebay for around $80. My other question is that when installing the header back to the engine, the four circular round clams have different grooves from top to bottom. There is no video which indicates which side is up or down. Do you know which side is up?

[@MotoMedic]

@@infojn-um8jm popping is normal when you remove the bread box. You can install block off plates to take the popping away, but you'll need a jumper for the module that controls the PAIR valve (the thing you'll remove). Mine doesn't pop anymore as I've installed the block offs. Those clamps are fine either way. You may want to change the exhaust gaskets though if you've had a decent number of miles before doing the delete. I didn't change mine since it had so few miles. So far no issues. Yours might work out thr same just be aware.

[@infojn-um8jm]

@@MotoMedic I have around 5K miles its 2023. Do you think I should replace the gasket?

[@128900nak]

Hi, thanks for detailed video. I ordered the midpipe and tried to install it on my z900 but when I was fixing the stock exhaust to this midpipe i noticed that the diameter of midpipe and exhaust is same and hence i couldnt install the midpipe. Did you also face the same situation, I see you also have installed stock exhaust on this midpipe.

[@MotoMedic]

Con esta modificación, deberás cortar la cámara grande, por lo que será difícil volver a colocarla. Puedes quitar el catalizador, pero a menos que agregues un encabezado completo, lo dejaría ahí. Me imagino que la pipa es muy parecida ya que están fabricadas en China.

[@128900nak]

@@MotoMedicoops…can you write this in english? Also, which year the bike is from?

[@MotoMedic]

Oops! Sorry! I'm in Mexico and I think it auto translated your post 😂. My pipe was a direct fit. But when I got it, it also came with a collar that would probably be just for that reason. I didn't use it like I said.. It was a perfect fit with the stock exhaust. My bike is a 2022. I'm not positive about any changes or different diameter pipes but maybe? 🤷🏻‍♂️

[@128900nak]

@@MotoMedic okay. Mine is from 2023 and exhaust diameter and the pipe’s diameter is same 51mm. Looks like there are changes in diameters from 2022 to 2023. Do you have an idea what is the diameter of your motorcycle’s exhaust?

[@eddwiggins4383]

Definitely doing this to my z900rs cafe!

[@RexMuffin]

Don’t. I did it, and the fitting is pretty bad. The exhaust leaks and sounds aweful. The cat where the mid pipe plugs in is not perfectly round and that’s what causes the leak. The angle of the mid pipe also isn’t right. Ended up having a full system installed with a tune at a performance shop. Don’t do the ghetto option, save your stock exhaust and spend money on a good system.

[@barnz008]

So baseline was about 80 dB and without the box or the muffler it was around 90? Seems consistent with other bikes I've done exhausts on. An increase of 10 dB will sound about twice as loud. Or for us old guys, twice as annoying. Mufflers FTW. Thanks for the data.

[@MotoMedic]

Earplugs 👍 I'm an old guy that used to be a touring metal guitarist. I know whatcha mean. Nice to have a clean sound though. My last bikes were fully open race bikes.... This is quiet in comparison. Old ZX6R was easily 120db at speed on the gas at 16k.

[@thatstheguy07]

I always thought you had to cut the cat off, and then I presumed there would be an issue next time I needed safety inspection. So you can just cut the bb off n it sounds better? Well I’ll be.

[@MotoMedic]

@@thatstheguy07 sounds slightly better.... Negligible.

[@danielramirez8695]

One question, Is removing the entire exhaust necessary for the cut? I’ve seen other videos where people make the cut for the mid pipe without taking off the exhaust and wondered if it’s only necessary if there’s limited room to work with or if it’s a required step.

[@MotoMedic]

Can it be done on the bike? Yeah. Is it a pain in the ass? yes. It's easier to remove it and have an easy place to do the work. Takes an extra 15 minutes and assures you that you don't have anything in the way to get around. Never half ass things on motorcycles.

Hi. Great video! Do you need ECU flash for it. Did you notice any changes with power, throttle response etc after ride Cheers

[@MotoMedic]

If you're not removing the catalytic material in the header then you're fine. It'll restrict just enough airflow so that it shouldn't need a flash. That isn't to say that you shouldn't go on ahead and get it done though. :) I'll be having mine done in the Spring when I'm home from my place a bit further south than Idaho.

[@riverburch5297]

Hey man, need a little help I bought my first sport bike (2007 triumph Daytona 675) a few months ago and about 2 weeks ago the bike stopped charging. I replaced the RR and the stator. That worked great for a day till it stopped charging again. From my multi tool I know it’s the stator, since it’s at 12.6 before starting and sits at 11.7 when running and revving. Should I replace the stator again? The connections are good but the old wires were a bit corroded wondering if it’s the wire issues or the whole stator. I would greatly appreciate anyone’s help or diagnosis.

[@MotoMedic]

I have a video on a 675 with this exact symptom. Go to my page and find that video and check out the comments section. I believe there were a few people who had this issue. I wasn't able to have the bike long enough to actually get into the weeds and locate the problem. But a lot of other owners chimed in and maybe something is there that will help. Sorry I'm not more help! Typically... that would be an easy fix. But apparently Triumph (like all Euro bikes) has to do things differently and with more electronics.
