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 😎👍🏻

by far easiest downpipe install i have seen so far 😲

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

@@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

[@BMWFanatic]

Thanks! And yep!

[@alessiogiribaldi3881]

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….

[@mikhailSRT4]

That does sound nice. Not a fan of some of these people with bang pop tunes. But the factory pops are acceptable

[@tavulechinois]

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.

[@sms4hou676]

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!

[@RTR_RRoomes73]

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

[@alsaku33]

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!

[@itzahstickup]

Yep i used this method makes it so easy

[@nicohagl]

@@itzahstickup but don't forget, to twist the wires can be bad for the sensor ;)

[@terrancepinkney777]

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! 👊

[@lordofbathurst]

Can you show off an acceleration video with this downpipe installed. Thanks!

[@noofff1768]

super video 👌👌 i have a z4 b48 , it's the same montage for the downpipe?

[@BMWFanatic]

Similar, yes

[@Rw.M240]

Any highway drone or anything. And how’s the cold starts for your neighbors. I want this for me 22 g42 m240

[@clifft7832]

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.

[@nicohagl]

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

[@arturoperez7831]

Hello, do you know what’s the torque spec for the turbo downpipe v-band? Thank you

[@josemeza3813]

Do you need a tune for the downpipe to work properly with no check engine light?

[@ElmeroMachin-ng3bv]

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?

[@lightbender1622]

Very well done video! How does performance compare? What is sound like at highway speeds and under hard acceleration?

[@BMWFanatic]

Sounds perfect - no drone 👌🏻

[@sam.raycars]

Good video mate did it throw EML on after a few days as sometimes it can

[@BMWFanatic]

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.

[@drewy2347]

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?

[@doubletapdieter6570]

great video! I'm assuming this install will be extremely similar a 2022 X3 M40i?!?!?!

[@BMWFanatic]

Yes it will

[@MortgageProGuides]

That is all you did to get that sound ? Or do you have a tune or some other engine mod ?

[@ExTrAhP500fr]

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

[@kanekickz7818]

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?

[@NathanArakel]

Is this with the muffler off? Or can the car still go back to quiet in comfort mode?

[@youngpaul6526]

Hi, can you tell me if this dowpipe can be installed on the stock exhaust?

[@empiretowing951]

I’ve got a 23 M340 how has the downpipe worked for you long-term? Would you recommend getting that specific one?

[@ximmen]

do you have to unplug the battery before you started?

[@evanruder1125]

are you running a tune with the dp.

[@raldyjimenez3319]

upgrading to AA down pipe doesn't need any tuning? just plug n play?

[@kanekickz7818]

What size socket is the v band clamp?

[@nickspondike5014]

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.

[@Jaayyenka]

Any difference in performance??

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

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??

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?

[@BMWFanatic]

This doesn’t throw a CEL period so no logs that “something has been messed with” since it’s a 400 high flow cat.

[@BMWFanatic]

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.

[@cpete0079]

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.

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 ?

[@BMWFanatic]

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
