Thanks guys for checking out the DIY! So simple to do on the B58 and hope my video helps ya out when you do it on your own 😎👍🏻
Could you feel a difference?
Amazing camera work nice and clear made this DYI look amazing 100/10
When reinstalling leave the o2 sensors off, feed down pipe from the top and “hang it” on the two studs. Snug up v-band then slip mid pipe. You can get to both o2 sensors with down pipe fully installed. Just my 2 cents in making the install easier. Nice car!
Yep i used this method makes it so easy
@@itzahstickup but don't forget, to twist the wires can be bad for the sensor ;)
@@nicohagl yep very important
Yep, another good method 👍🏻
Just have to remove the heat shield or the whole air box too?
Thanks for the video, I installed that AA DP on my 2020. 1.5 hrs start to finish and no check engine light. It made a real big difference in sound.
Did you need a bridge or will some lifteners are okay?
Great quality video for a DIY install. Really clear and well lit. Made the job look easy.
Thanks! 👍
thanks for the awesome video, did my downpipe now and this video helped alot especially taking off the 02 clips on top. now to tune her :)
I watched this video to confirm that I will have to pay someone to do this work for me.
I'll do it for you if you're in socal
haha. legendary. same.
Wtf this hella easy
Don’t be intimidated you can do it
like everything in life you’ve got to try new things
Believe in yourself bud !
Lol, it’s not as bad as you think.
by far easiest downpipe install i have seen so far 😲
Love the video just got my 21 cant wait to buy a downpipe what brand would you recommend. Great video you made me a subscriber wish you were in FL i bring the car over
Do you need a tune for the downpipe to work properly with no check engine light?
U def a bmw mechanic, no way u would knew about the clips above. Man ur a master amazing video
i dont have this car, but im trying to get one after selling my wrx, this install looks so easy from this vid!! awesome footage, very excellent camera angles
Damn! Installing downpipe on 2022 m340i. I have 2021 m340i with B58TU, I bought the same downpipe but Im so reluctant to install it, Im so dumb to buy it. I didnt know Im gonna lose my warranty. Thank you for showing us how to install it DIY. Mad respect to you putting downpipe under full warranty car.
I’ll buy it off of you if you’re not gonna install it
I just took it off if I went in for any warranty work
@@BMWFanatic you could just swap the stock one back over right if you ever gotta take it into the dealership for maintenance. They won’t be able to know right since it doesn’t throw a cel
One of the best install videos I found. Thank you! Should be pretty close to my 240i B58TU right?
Thanks! And yep!
I did it on my own for my first time on a b58 and used on the decat downpipe new gasket but the side that is on the turbo it smoked a little bit and stopped now i did 300 km with tune and there is nothing everything looks good my question is did i forgot something or does it need a gasket to on the turbo it self and one on the downpipe and then mount the downpipe or is it all good
Hello sir, Thank you for the great video! I wonder if you have stock Exhaust on your car?
Great video, thank you for sharing. For a Bmw M440 2023 i need 1 or 2 downpipes? Do you recommend catless or catted? In terms of hp gain and compatibility….
Does this void the warranty? No tune required with this mod?
No tune needed, but a tune will get the max benefit of course. No CEL with this downpipe so it’s a win win. The part has to be at fault to void a warranty which would be the downpipe warranty part not everything else. It’s a simple install, so worst case scenario you could always swap out to the stock one if you’re having any kind of engine or turbo warranty issues.
Do you know what cell the stock cat has compared to that 400 cell
Closer to 800
@@BMWFanatic thx
I have the same car but I am seriously debating to get a catless and just get the check engine light reset, does it smell like gasoline at all?
I know o2 sensors are bank 1 and 2 but are they the same sensor and they’ll fit each other?
will the gen 1 AA downpipe fit on the gen2 b58
What’s the lift that you use?
That is all you did to get that sound ?
Or do you have a tune or some other engine mod ?
do you have to unplug the battery before you started?
Have you some specs to the rims, size and manufacturer, thx

On the O2 sensors, standing from the passenger side and looking at them…just remember, “white is right”….then you won’t forget
Great install video, thank you! Perhaps some more sound clips in the near future? 🤔
Hello, do you know what’s the torque spec for the turbo downpipe v-band? Thank you
upgrading to AA down pipe doesn't need any tuning? just plug n play?
I have a 2019 bmw x4 m40i! I just got a vrsf downpipe, this should be about the same for the most part considering mine is a b58 as well?
I’ve got a 23 M340 how has the downpipe worked for you long-term? Would you recommend getting that specific one?
That does sound nice. Not a fan of some of these people with bang pop tunes. But the factory pops are acceptable
Great stuff Lee. And the sound is great too. Dutch regards, Nico.
Looking to get my Downpipe and Cold air Intake along with JB+ to be installed on my X5 45e
Should get near 450 HP at that time and more efficient power distribution
Any highway drone or anything. And how’s the cold starts for your neighbors. I want this for me 22 g42 m240
why does it feel like those jacks are awesome but scary at the same time.
They are sure awesome and I use them weekly for stuff! They have locking points on each side like a jack stand that you lower it down to lock into place. I had my 335i up in that locking position for 3 months last year and always very solid 👍🏻
😂😂😂 foreal
I've been able to get everything done except connect the new AA DP to the midpipe. I cannot for the life of me get it to fit into the pre-existing midpipe. The v-band clamp is completely loose too... Do you have any tips on fitting it in?
Great video and commentary, really helpful!
super video 👌👌 i have a z4 b48 , it's the same montage for the downpipe?
Similar, yes
For m$1500, the company should send someone to install it for free, and buy me lunch. 😜
Does this void the warranty? Are there logs they can point to to prove it? If you remove it and put the stock one on, will they still now from the data logs?
This doesn’t throw a CEL period so no logs that “something has been messed with” since it’s a 400 high flow cat.
The part has to be at fault to void a warranty which would be the downpipe warranty part not everything else. It’s a simple install, so worst case scenario you could always swap out to the stock one if you’re having any kind of engine or turbo warranty issues.
Nice tutorial. It's easier to do than an E46! BMW thought that many people would change their downpipe themselves! Is a remap is mandatory to avoid check engine light?
Hope more vids with accels and flyby.
The ease of changeout is a a factor of added clearance which they needed to cool the engine compartment to improve engine /plastic parts life. That's what I understand. Bonus! Easy to change out the downpipe!
are you running a tune with the dp.
Did you have to tune it after installation? I have a 2021 with locked ecu and looking to go catted but not sure if i need to tune it after installing? Love the car 🔥
No tune required at all
Is this with the muffler off? Or can the car still go back to quiet in comfort mode?
Good video mate did it throw EML on after a few days as sometimes it can
Nope, never did after 2K miles. Guaranteed no check engine light. I do know that some people have experienced it, but they would warrantee that and replace.
great video! I'm assuming this install will be extremely similar a 2022 X3 M40i?!?!?!
Yes it will
Great lighting and editing! I have a 2018 540i that I want to do this on, but I don't want much more noise. Was your car a little rumbly before the install? I wonder if the 5 series is a little quieter before and after.
it will be louder and if you do have burble it will be more strong😁. I think u can compare it to a resonator delete
Very well done video! How does performance compare? What is sound like at highway speeds and under hard acceleration?
Sounds perfect - no drone 👌🏻
What kind of rims are those? Awesome
These right here INSTALLING AGGRESSIVE WHEELS ON MY BMW M340i!
ruclips.net/video/k5QKjBoXtGI/видео.html
woow that quite a bit louder than stock. Sounds perfect! Will buy one for my M140i
Yeah I was shocked honestly when I fired it up haha
All good though!!
@@BMWFanatic can you make a driving by video and an inside video while driving? Curious :)
@@BMWFanatic would you say it’s significant louder? The cold start is what im worried about
Man you are the GOAT for this one! Great camera work, super easy to understand and the install seems pretty easy to do. I have 540i M-Sport and I think I will go ahead and do this myself! Thanks brotha! 👊
What size socket is the v band clamp?
Is it supposed smell like gas when you go with dp with no cats? Did mine on n54 and it smells bad I can smell it thru the vents. And it sounds terrible like if there is a leak. Any way to tell if there is a leak ?
Correct, if you remove the cat then you’ll get all the exhaust gas fumes. High flow catted like this will have a SLIGHT smell but it’s noting like catless
Which jacks are these
Do you have the stock m exhaust? Or is it the regular exhaust with the new down pipe?
Stock regular one
@@BMWFanatic thank you
Do you *have* to tune the car after installing a DP? I know the AA DP won't throw a CEL, I'm just wondering if I can install it without tuning it.
You don’t have to tune it, but when you do tune, it will bring out the benefit with using the downpipe
What rims are those? They’re perfect for the m340i!

Why not go with the catless downpipe? Is it because you are a super follow the rules, by the book, straight laced, clean cut type guy? :D
No need to disconnect battery?
Man that sounds so good!
Does this void the warranty?
Did you have MPE? Or just regular exhaust? Cheers!
Looks like it’s just stock not even MPE
Just regular
is it with a catted downpipe?
Very nice video. Love the garage.
Can you show off an acceleration video with this downpipe installed. Thanks!
Does this void my warranty?
Excellent tutorial sir.
I losened the v clamp bolt a lot but the clamp is still so tight
Might be stuck a little bit - could try a thick flat head to try to get it to pop loose
Remove nut and bolt altogether.
Any smell? Even mild?
Power gains?
Any difference in performance??
Are activeautowerke downpipes any better than other brands of downpipes? Is the downpipe free of problems during exhaust inspection?
This is a GESI cat, so pricer and 400 cell, so no CEL
That’s where the price difference comes into play
Why the special tool for removing the 02 censors?
+1
Isn't a proper-sized open wrench good enough?
Does the downpipe cause a check engine light?
This one does not, guaranteed
No need of ecu coding? No check engine light after?
depends on the cat. if 200cells its a 50/50. with a 300cell imo it will not
No cell with this cat as it’s a 400 cell and no coding.
Where the rims from ?
If you’re going to tune it, makes more sense to go go with VRSF 200 cell DP for $500 and code off the CEL. Way better flow and sound for 1/3 of the price.
Bro can we still order m340i 2022 version ?
Did you get a CEL ?
You don’t get a CEL with this downpipe
@@BMWFanatic Thanks for replying. I'm trying to decide between this one and the stone exhaust eddy catted downpipe.
2020 or mild hybrid?
does downpipe increase performance or its just makes it sound better
It will increase some, but need a tune to really make it shine
I have a similar setup, with an AWE catback exhaust. Which tune are you thinking about? I’m on the fence with carbahn, BM3, or Ecutek… I’m in Ohio also, so if you know of a good tuner fill me in!
Just noticed you have a 2022, so your ECU is locked down! Not too many flash options… so I assume you’ll do a piggy back??
Do ecu tek. Its best
How much BHP with downpipe+Intake+Tune? between 440 and 480 ?
Probably close to 480whp on e
this car is easy to work on
So easy indeed
Wheel link please
Hey, would I be able to pass inspection with this downpipe?
no
@@nomanmana4256 explain why he wouldn’t? this is a catted downpipe
@@srsly3602 with a catted downpipe depending on where u are and the type of downpipe (state wise) you won’t pass inspection but you also won’t get a check engine light!!
@@nomanmana4256 I honestly don't think a single person doing a safety or emissions inspection is going to bother looking around and be like "ruh roh, this is an aftermarket downpipe...you fail."
I got a cel on my catted dp ..
Is this RWD?
Hey is it okay to run the dp and no tune for a while?
following
Of course
A tune just brings out the true gains with a dp
Hi, can you tell me if this dowpipe can be installed on the stock exhaust?
ssems to me that this is a fools errand because upgrading the downpipe should serve 2 purposes 1 is flow which is obviously an improvement the 2nd however removes the catslyst so that when your using things like antilag and sending raw fuel into the exhaust you dont make excessive amounts of heat which with a cat your going to do. heat way beyond what the car is designed to handle safely. so this may look like a win win and you wont have problems with the o2 sensor over time its going to cause far bigger problems than a simple o2 sensor trouble code. heat is what ages a car faster than anything. just look at any car with all highway miles versus one that has miles in stop and go traffic.
how much clearance do I need to do this job? Can I do it on a ramp?
Depends how high the ramp is, but I think you could do it. Just will be tight pulling it out and then putting the new one back in
I have to ask as i have been stumped trying to figure out what differentiates a high quality down pipe from an inferior one. The prices range from $450 up to $2300. Can anyone explain the differences? I want to go with a catted version.
Catted is always more expensive
@@aarondostou3888 will it throw a code if it’s not tuned?
@@kolourblind3124 no it shouldn’t
Yeah catted ones are always more because you’re paying for a high quality cat. 400 cell and up won’t throw a CEL
Are you sure it doesn’t turn on the down pipes ??
?
The fact that shops want 800 for this is insane.
I got quoted 950😂
Any CEL yet? Lol
You’ll never get a CEL running this DP :)
Bro changed rims
Upstream, Downstream
Yes
