[@PunchMan00]

Getting that g20 soon can’t wait to have this exhaust 😫

[@valvetronic]

let’s gooooo

[@sleepy2945]

installing mine today, hella excited

[@valvetronic]

Enjoy it!!

[@sunny.blendz]

question what do you do with the oem valves? Do you hide them above the exhaust heatshield and if so do you zip tie them closed?

[@carsandcoldbrew6489]

Sounds very close to the S58.

[@JayPozo]

Do you have a sample of the system on a 2023? I’m trying to find something that doesn’t burble too much. I understand the 2020 tends to burble, even stock.

Does this exhaust fit the m440i g26 gran coupe too?

[@valvetronic]

yes it does! And we’ve had great success with that platform as well. It’s the ultimate exhaust solution for M440i

[@nathankotz8651]

I have a 2021 and I swear mine doesn't burble like that. Is that a 2020 thing or is that caused by the exhaust?

[@Nytro423]

Burbles are made by the engine, not the exhaust

[@DavidDahan05]

Will this sound the same on a 2021 M440i??

[@valvetronic]

yes sir!

[@DavidDahan05]

@@valvetronicthanking for responding so quick !! Because I saw another video you posted and there was no verbles

[@zackalhasan7587]

@@DavidDahan05the 2021 is tuned differently tho so there’s less burbles im pretty sure

[@alexciofu666]

[@valvetronic]

only the exhaust

[@G20T]

I can barley here it I have to here it in person videos don’t do justice

[@DavidDahan05]

Is this stock downpipe?

[@DavidDahan05]

This fits on 2021 model right?

[@valvetronic]

2020 stock

[@zachaeus06]

@@valvetronicthanks for replying! If I were to get a 2023 and install this with dp would it still sound like this? The burbles too? Even with the new locked ECU?

[@TnyBim]

So this is how my g42 M240i would sound. 😂🤌
