2021 YAMAHA MT09 EXHAUST FLY BY!! POPS / FLAMES.

[@mullenli]

Pretty nice looking , sounds and performance. Can’t go wrong with this full system

[@ridineuzz]

the bike is very cool, but the exhaust for me looks very big. if i could, i would put a small one.

[@MyMotoSpot]

Akra + MT09 = fantastic stuff! Is that a beeline navigator on your handle bar? Subsed, support and stay connected

[@Builtmoto]

Yes it is! And Thank you!

[@Travis-pv9kj]

Can’t wait for mine to show up, the Akra is sitting at home just waiting for the bike to show up lol

[@Builtmoto]

I got lucky and got one of the first ones here in the states and now it seems that are not getting any new ones.

[@SiLENT__]

I am in love with the sound of the Akrapovic but why in the world is it that laaaarge :(

[@Builtmoto]

I agree. I assume it has something to do with the tuning of the bike or for the exhaust pressure control.

[@exothermal.sprocket]

The air injection system is worthless without the CAT. That's where your popping comes from. I don't know if they will, but the pre-2021 MT models had availability with CS Racing, from Brazil. Nice underbelly system with side exit and trim, for affordable prices. They'll probably put out a 2021 version soon. For most bikes, their sound is second to none.

[@Builtmoto]

I am aware of the AIS system causing the pops but at this time there is no check engine lamp for it or any block off plates for the 2021 models. And I will have to take a look at CS to see when they come out with a system that sits lower.

[@exothermal.sprocket]

@@Builtmoto Yeah, there's no fault light for the air injection because it doesn't affect engine function, only downstream exhaust. What would throw a code is the removal of an O2 sensor.

[@MotocasalDaMT09]

Vídeo top.

[@mtblife7335]

Why is the backfire/pop so strong? Could there be a leak?

[@Average_D]

Sounds so good as always from Akra. Just honestly hate the way it looks. I really have no idea what they were thinking by not keeping the same style low key can from the previous Gen mt’s. It fit the bike perfectly! I just can’t like it no matter how hard I try. I’m going for the Yoshimura AT2 which also sounds good but imho, looks much better. Bike is looking sharp bud!

[@Builtmoto]

I agree! I actually just ordered the dominator gp3 exhaust just because it looks better. We will see just how bad it sound though

[@Average_D]

@@Builtmoto I think the gp3 sounds good. Definitely going to be a bit louder but certainly looks better. 👌🏼

[@Sw1tchTube]

How do you like it now you've had it for a year? I'm actually eyeing the HP3 Full Low Exhaust it's not quite as loud and tinny as the GP3@@Builtmoto

[@jacobevans9758]

Do you have any videos off the flames?

[@Builtmoto]

I do not sadly. I have tried to get a friend to film for me but the flames can only really been seen when it is dark and when the bike is coming down from high RPM

[@henrikhh]

NICE :-)

[@Builtmoto]

Thanks!

[@gregmochty1836]

Is this with the db killer in or out??? Can you tame the sound down at all??

[@Builtmoto]

It is with the DB killer out. I took it out before the exhaust was actually installed. The DB killer will leave the idle sound very similar but will make the bike much quieter when riding down the road.

[@racketbrass2686]

Where did you get the blue rims we have the same model but mine are orangish

[@racketbrass2686]

Also, where’d you get the blue front fairings?

[@Builtmoto]

I took the wheels and front fairing off and had them repainted to a Porsche color. (Mexico blue) I have a earlier video talking about that a little bit more in depth.

[@racketbrass2686]

@@Builtmoto yeah I ended up going through all your videos haha 👍🏼 definitely subbed. looking forward to more modification vids.

[@Builtmoto]

awesome thanks man and I have some big things coming pretty sure

[@jackie977]

Bro,I got the same exhaust but not so many pops like yours,what should I do

[@Builtmoto]

when i had the bike i had make it pop sometimes by opening the throttle a little bit on deceleration. also i do not remember if i had it tuned at this point so that could also be one of the things making it pop, i used a vcyclenut tune on mine and it was a very safe but powerful tune

[@1985safraz]

Ordered mine still waiting apparently shipping container yet to go through customs due due to brexshit so I've been told I reside in england enjoy the bike bro

[@Builtmoto]

that really sucks, I got one of the bikes that came on the first delivery at the dealer, and the dealer still has not got another delivery yet. so I got lucky to get mine when I did.

[@Dtp2296]

Nothing to do with brexit, it's been semiconductor issues. yamaha are not getting any more into the uk till march, any dealer tells you otherwise they're just wanting to get your deposit money. I am also waiting (deposit paid end of july) just been offered they're ex demo for very little discount due to demand

[@1985safraz]

@@Dtp2296 oh my They trying to entice you with the offer

[@Dtp2296]

@@1985safraz i'm very tempted, took it out today, awesome bike!. 1000 miles of people testing it out though is a little off putting

[@HusseinMarey]

Any drone on the highway?

[@Builtmoto]

not too bad when cruising but at 8000 RPM and higher it does.

[@hardstylegaming100]

Have you done anything for it to pop and flames or just changed to akra exhaust?

[@Builtmoto]

The bike has popped on deceleration ever since I installed the exhaust.

[@hardstylegaming100]

@@Builtmoto nice, you think its the same on the 2021 SP version?

[@Builtmoto]

yes I believe so since the engine and engine tuning was no different between the standard bike and the SP version

[@hardstylegaming100]

Okay, have you done any tuning on the engine or is it stock?

[@Builtmoto]

there is no tuning available at this time for the bike. I know that power commander is working on a tune but they have no eta at this time.

[@SJ_999]

So do you not need a ecu flash for an aftermarket exhaust? Because I was looking at the Mivv X-m5 Black Racing Full Exhaust

[@Builtmoto]

no you do not need a tune according to Akrapovic. The AIS (Air Injection System) does cause a little bit more popping that usual when the exhaust is installed but the bike has been riding fine and I have 2000 miles on the bike with the exhaust.

[@DW-hx1xm]

I put mine exhaust on before 1 st service.. yamaha adjusted air fuel mix for me on 600 mile service 👌. I said I was worried about voiding warranty. They couldn't give a .... 🙃

[@BoostedBoyd]

dont need a tune but the bike will run much much better with one. I had the akra carbon full exhaust on my 2019 MT and it ran like shit. Along with alot of decel pop. Just tuned the bike and now its a total beast and smooth as silk. Night and day difference. Virtually no decel pop anymore. Anyone who says you dont need a tune never ran the bike with a tune because there is no comparison. I thought the same and boy was I wrong. Do yourself a favor and get a tune with your exhaust.

[@bert8892]

Great video but you need a 360° camera

[@Builtmoto]

I actually ordered one last night! thank you though

[@DW-hx1xm]

Please don't use it there horrible to watch

[@ADDONRACER]

Not really

[@TheGuud44]

Yo I bought those levers in your description for my 2021 my-09 and they didn’t fit. Can you help me

[@Builtmoto]

hey man I am sorry that those did not work, I had talked about it in my 4 must do mods where the brake side did not fit. I have found some other that I believe will fit but I want to get them installed and ensure that they function well before uploading a video on them.

[@TheGuud44]

@@Builtmoto okay thank you. I’ll be looking forward to seeing if they work, hopefully they do

[@MashMann77]

2015+ R1/R1M Levers will fit the 2021 mt09 (not the SP model due to cruise control). This link in the description takes you to

[@audiolover]

Looks like AliExpress exhaust for 2021 mt-09...also disable AIS system ECU to get rid of this stupid pops

[@povilaslondon]

so where are the flames?? :D

[@Builtmoto]

I could never get a camera to stay fixed under the tail of the bike so I never got a good video of the flames lol
