How to: Yamaha MT07 2021 Akrapovic Exhaust Install 

Haha, thanks man! I'm hoping I can still find the time for one or two videos this season. It's getting pretty cold already in my Area😅

I drove the stock exhaust for about 3000 km, before I swapped to the Akrapovic. The sound is very different. Not much louder, but a completely different note.

@@htmt07 ok, maybe the sound doesent get that accurate over a video. I drove mine with stock for 13k km. Also i think the Akra will become a bit better with time.

@Tigerblood1940PS3 I think it does get louder over time. It's hard to tell, because I don't have a direct comparison to a brand new exhaust. Mine has now about 10000km on it.

Thank you very much. Just use a small dab of any grease. It's just there so the Gasket doesn't drop down. As soon as you start the engine the first time, all of it evaporates. So don't use too much of it. It might do damage to the Catalytic Converter.

Hi, vielen Dank. Ja, das Fett ist ganz normales Fett. Das soll da auch nichts schmieren, sondern nur bewirken, dass die Dichtungen bei der Montage kleben bleiben. Ich habe nachträglich neue Dichtungen verbaut. Zum Zeitpunkt der Auspuffmontage waren die Dichtungen nicht lieferbar.

Ich habe die hässlichen "Antennen" rausgeschraubt und stattdessen Linsenschrauben eingesetzt 😂.

In camparison to the stock Euro 5 exhaust, it's a big difference. But it's not really loud. I try to explain as detailed as possible: With the stock exhaust, I could only hear the engine up to a speed of roughly 70 kph. With the Akrapovic the wind noise drowns out the exhaust note at about 110 kph. I use to have a Roadsitalia Thunder Exhaust, where I still could hear the engine at 160 kph (but that was obnoxiously loud) My Helmet is a Skorpion Exo 1400 Carbon. If you want a high value exhaust, get Akrapovic or SC Project, if you want more sound, go for the cheaper (but also very nice quality) Options. But remember, depending on the country you live in, you might get in trouble with the authorities 😉.

@@htmt07 thanks for answering :D

No, I didn't flash the ECU. You are absolutely right, this will 100% void the warranty.

No. Never got a check engine light. Did you unplug your O2 sensor before unscrewing it? If not, there is a good chance, you broke it. In pretty much all tutorials, they do it wrong.

That was just some random grease to make the gaskets stick to the cylinder head. You could also use some regular butter for that😂

Correct. I didn't use one in that case. If you're experienced with thightening bolts, you don't really need a torque wrench. But I wouldn't recommend tightening wheel nuts just "by feel".

I need to have look into it again. But as far as I remember it's just one tap that secures the connector to itself. With the other two you disassemble the connector.

@@htmt07 thank you very much! then i'll try to unlock the front one with a flat screwdriver.. thanks again :-)

Yes. But it doesn't need much force. So be careful not to snap the latch

@@htmt07 precious advice, very kind.. thank you again!!

Yeah, mine is for the 2021-20xx Euro 5 Version. I like the Akrapovic for not being Obnoxiously loud. I had a Roadsitalia Thunder mounted first and hated it for the annoying noises it made 😂. But I got to say, I was disappointed by the finish on the Akra Headers. Scuffmarks and dents all over the piping. Defenetly not what I expect for this price.

@@htmt07 aye I don't think they're that well made. Having the cat will probably restrict flow.

@@BenTV73 Might be. But it's a very high flow Cat. Had a similar one in my Turbo Miata. On the Roadsitalia the same density cat was included, but the diameter was the same as the exhaust tubing. This restricted flow defenetly.

I wrote to Akrapovic, because according to the installation manual there should be an arrow indicating the Gas flow direction. Mine didn't have it and the Customer service told me it wouldn't matter. So I put the Cat in the way that I can read the writing. So far no problems

@@htmt07 thx alot mate

😂 No, not gonna Happen 😂

What could happen if you reuse them?

Panda is technically not wrong. If they leak, due to dynamic Pressure, fresh air could get sucked into the exhaust. Since in this case it happens in front of the O2 Sensor, the ECU will enrich the mix. So you consume more fuel. If your engine runs very, very rich, the excess fuel could wash the Oil from Pistons and Cylinder walls, which can result in a blown engine. I couldn't get new Gaskets in time, since they weren't available. But now they are changed.

@@htmt07 what did you use to make the new gaskets stick?

Finally they came back in stock, so I bought them😅

@@htmt07 did you use grease to stick them on?

55€ von AliExpress. Kostet inzwischen um die 85€. a.aliexpress.com/_vqXanX

I bought it on Jamparts.com. But I don't know it they ship worldwide.

No. Runs perfectly fine like this. I know, all tuners say, it runs quite lean under power, but this is, what Euro 5 is all about. It needs the high exhaust gas temperatures for emissions.

That's a super cheap one from AliExpress. I paid 50€ for the kit.

I bought it from AliExpress. Cost me 50€ including shipping to Europe

Sorry for the inconvenience. You might want to carefully loosen the bolts again. I didn't had to change the bolts, but if exhaust bolts snap, it could be really bad. In the worst case including drilling out the bolts from the cylinder Head😑

And? How did it go out? I hope everything went well.

@@htmt07 i will let it stay as it is, seems like its only one of the flange thats tiny bent and I dont think that torque will be any danger for the bike, its not skyhigh over the standard (also think that i put the torque wrench on around 37nm) and im afraid of leaks if i loosen it :) Seen videos where people go full ham without torque wrench so around 10+nm shouldnt be to bad 😊

But the flange is supposed to be slightly curved, if you mean this. You can see also a curve on mine arround the 9:00 and also at 14:30 marc. This makes the bolt appear slightly bent as well. I don't know if I would leave the bolts overtorqued, though. To much stress plus a lot of heatcyles might weaken the bolt. I'm feel really sorry for the mistake I made in the Video. Imagine me spending hours and hours of (unprofessional) Video Editing and double checking to have all the clips set in the right order just to realise this mistake after the Video was live for about two weeks🤦🏻

@@htmt07 mine might be a little bit extra bent but its not really much after googling on some other people. Hmm, might release it a tiny bit then just to be on the safe side, shouldnt leak anyway, got new gaskets when i installed it as well. Yeah i can underatand ur feeling but the blame is all mine, i watched the video 3 times before installing and some where in my head i knew that the torque was changed, but in all excitement i forgot about it and had for some weird reason disabled the subs 😅

It's the Akrapovic Part Number S-Y7R8-HEGEHT. Do yourself a favour and check a lot of online shops. When I ordered mine, there was a price difference of up to 800€ between shops. I ordered on Jamparts. com, if that helps.

@@htmt07 hey, I am planning to buy this one!! Is it any louder than stock? I hate it when I can't hear my motor due to the wind 😩 unfortunately, other exhausts require a tune which I do not want to bother but sound much different.

It is louder, but not by much. If you just want noise, don't buy this exhaust.

@@htmt07 ​​⁠ I don't want to be sound like a 100cc bike 😅 with that being said, I like the sound (grunt) that you have in your intro (0:04) of your vid (low rpms) but I hate the high pitch sound that you get without db killers at high rpms.

The sound in my intro is with a "Roadsitalia Thunder" Exhaust😂

Hi Iván. I don´t use Spotify, but the first Song is called: Hang Ups (Want You) by Otis McDonald

The Brand Name is "ConStands" It does, what it's supposed to do, but honestly it's quite fiddly to use.

I'm not sure. Probably about 7000 km.

@@htmt07 hmmm is there a required amount of odo before you change your exhaust?

No. You can change the exhaust anytime

@@htmt07 alright thanks 👌

It's supplied with exhaust system to extend the stock O2 Sensor cable.

È obbligatorio il cavo adattatore o può bastare anche solo quello originale per montare l akrapovic? ​@@htmt07

It is required to mount the o² Sensor. It comes with the Exhaust

No, I didn't.

@@htmt07 did you notice any power difference after installing the exhaust and not tuning the ECU? I want to put one on mine and nobody around me does tuning.

@@kevinjacquin5232 No, I don't feel any power difference. But that's not what I am looking for. If I want more power, I'm going to buy a stronger bike. If you add the cost of the Akrapovic plus the cost of a remap to the purchase price of the MT07, you are just a few hundred Bucks short of the price of an MT09

@@htmt07 Then what are you looking for? Just cool sounds from your bike?

@@Pilpellon I wanted to be able to hear my Bike, when i´m going faster than 80 km/h and wanted some more Premium look. And the Akrapovic was on a 500€ Discount, when i bought it. So i´m almost certain, i get my money back, if i sell the Exhaust separate from the Bike.👍👍

Yes. You can see it at 6:55

Je suis désolé, je ne comprends pas. De quelle ligne parlez-vous ?

I don't know about that. I don't even know if this really fits🤷‍♂️. Would be interesting to know

It probably is. Even if it's not too loud, it's not an exhaust build and designed NOT for this bike. So it's illegal no matter what 🤣

@@htmt07 and I thought germany was a cool country lol, my dream was moving there and go to the Nurburgring

As far as I know, the Exhaust Manifold of the Euro 4 Model fits on the Euro 5 rear silencer. But depending where you live, it's highly illegal.

Pelo menos não é tão mau como o Exaustão de Estoque :-D

bra I ain't doin that. Reason is explained in the Comments

Esto se debe a la normativa Euro 5. Es el futuro 🤮. Dentro de 10 años desearías que una moto nueva hiciera tanto ruido🤣.

es el silenciador. Tira-lo e suene como una biesta.

No voy a desmontar mi Akrapovic. Son demasiado caros para eso. Además, la policía alemana confiscará tu moto por eso.

pero que dices... esta moto con el escape cambiado es otro mundo...

Lo siento, no lo entiendo. El español no es mi idioma natural. ¿Qué quiere decir?

But then it's not legal anymore and on the first police checkpoint, they confiscate the bike and I have to take a taxi home. I'm okay with the bike not making a lot of noise

@@htmt07 Fair enough, then again just stupid to spend all them euros and the difference is okay at best.

I disagree. The exhaust is still lighter and better looking than the stock Tin can. And there is a difference in sound.

@@htmt07 There is yeah, just not a difference of a 1000 euros. How do I know this? Because I have that exact system, just EURO3 version, which is more loud.

I agree. There are louder exhaust systems out there, which I owned before. I mentioned that in another comment already, but the other brand was so loud, I felt embarrassed to drive around like this. That's why I went for a quality product, that gives me (a little bit) more noise, less weight and better materials. Is it sensible to buy a 1300€ exhaust for a 7000€ bike? Defenetly not. Do I regret it? Defenetly not. In fact, I would do the same thing again, except for buying a cheap exhaust before buying a good brand.

I'm not going to. I can't be arsed to deal with police every time i ride. Even though it might still meet the legal limit of this bike (what I doubt), it's still an illegal modification that voids the registration. Different Countries work with different laws and punishments

Welcome to the world of twobangers.

@@htmt07 my honest review like tractor

I totally agree. The sound of it is not really what I like. I already wrote that in another comment. I had a different exhausts first (Roadsitalia Thunder) which made it even worse. But seriously, the sound is not, what this bike is about. It's nimble, has a torquie engine and it's quite cheap compared to other brands. That's why it's one of the most sold motorcycles worldwide.

@@htmt07 why didnt u like the roads italia exhousts?

@alwayshigh0291 Because the exhaust is way to loud and the sound is absolutely stupid. It literally sounds like one of those lawn mower tractors with the Roadsitalia.
