Keep The BMW G20 Exhaust Valve Always Open | Free Mod | 2019 BMW 330i | 2020 M340i | 3 Series

I have been wanting to do this mod for the past year, finally I did it and documented the process. It takes a few minutes to figure out how to pull it but it is fairly easy. Make sure you put the car in sport mode and let it heat up, once you hear the valve make the sound that it has opened and the car is idling quietly, it should be ready. You can then pull the wire from the controller to keep the valve open at all times. This increases the startup sound greatly and allows for more backfires at low RPMs. You can do this on any BMW G20 Series from the 2019 330i, 2020 330i, 2020 M340i and most likely the 2021 models too once they drop. Keeping this open is the easiest, cheapest, free mod that you can do on a BMW G Series, 3-Series.

I think you also need to seal the female plug.

Does doing this have any sort of negative side effect? Does it provide any benefits? Sorry I dont rly understand what this does

[thekudkadog]

Can you throw in a small video with you driving in different modes when it is like this? Just to see how it sounds

[WilliamTan]

Dope tip bro, can we get a better exhaust clip?

[vpex]

hey just wondering i just did this on my car and is it safe to do this or will water or whatever damage anything?

[YoussefBahaji]

Oh snap it worked! any side effects or none to worry about ?

[azarath]

Just did it on 19 330i, which has nice stock burbles, and it sounds so much nicer. I don’t know why the valves close when in drive, as I noticed that they open in sport mode when in park, neutral, or reverse, but close as soon as I put the car into drive.

I would assume that it would be better for them to stay open, as the car is able to exhaust easier as it has both the left and right pipes to let the gasses out of now.

If you’re debating on doing it, I’d say why not, you can always reconnect she harness.

If youre in europe, this will throw an engine light. We have PPFs (petrol particulate filters) here and to do a regen the valve needs to be closed. USA is all good as you dont have PPFs.

[joshuaeghbali]

I tried many times to unclip it but I couldn’t. Can you help?

[JesusGonzalez-khdf]

the tape is going to melt and you will not be able to take it off

[jp]

So the check engine light wont turn on if you unplug it?

[fegari]

You can also start on Sport mode and avoid all that. If you leave like that, protect the contacts on the valve as well!

[franktsui]

Is keeping the valve open better for the car or not?

[falck]

just remove the connection rod and put it back upside down with tention so the engine part moves freely and the valve is locked in open position

[antoniosainato]

If I’m going this the engine light come up ?

[peterserhan]

aywa l sayedd. Waiting for your next upload (upload more wla)

[srali]

am new to this can some explain why your doing this whats the purpose behind this and will this affect the car in any way

[richardconter]

Got a 2021 m340i and I can’t seem to remove the clip by any means bruh

[ether]

Well wouldn’t it close if you turn the engine off?

Unplugging that valve barley did anything and it also didn’t sound as loud in the cabin with sport mode on.
