Thanks for this man appreciate you posting and doing the leg work

Great vid. It does make a difference, specially after a hard drive

[@BuffDrive]

It’s a lot louder than stock and yes it’s a little louder after a hard drive.

Hi dear, i like ur videos. Can u pls post a video on MPE on how is it like in eco pro mode. Does it drone or is it annoying to drive coz sometime you want your car in silent mode like eco pro that comes with stock exhaust. Would love to see the video on mpe noise and drive in eco pro mode.

[@BuffDrive]

Eco pro still not completely quiet there will be little amount of exhaust noise even if you press gas pedal just a little bit. You can see in my review video minute 23.30 it was in eco pro mode

[@Chris-bs8ro]

Beautiful M340i! What's the spoiler you have on your car? It looks so sick, and its exactly the one I'm looking for mine

[@BuffDrive]

It’s M3 style carbon spoiler

[@Chris-bs8ro]

@@BuffDrive thanks! G80 M3 or M3 CS spoiler?

[@antekrockys]

What you have done to mild hybrid system? Cuted it off? Decoded?

[@BuffDrive]

M340i LCI here in Thailand does not come with mild hybrid system.

[@dnlmch]

@@BuffDriveSame as Japan. No OPF and 48v mild hybrid.

[@gazhonzo618]

Sounds great, any chance you know what the part number is for the m performance exhaust?

[@Bran432]

za4

[@jaketay9373]

did you do any tuning to make it pop?

[@BuffDrive]

No, this is completely stock except the Mper exhaust. It’s only pop some times in Sport plus mode

[@matthewretrosi7111]

downpipes or no?

[@BuffDrive]

No downpipe

[@m3forty780]

2023 or 2024?

[@BuffDrive]

2023

[@m3forty780]

@@BuffDrive Thx. How was the stock exhaust sound? Very muted? Just picked up a 2024 and had my 2021 MPE transferred over (getting it today). I found the stock exhaust on the 2021 noticeably louder vs the 2024 LCI.

[@BuffDrive]

I won’t say it’s muted. It’s actually quite loud but that’s might be because mine doesn’t have OPF. The M performance is perfect for me. Your LCI after fitted the M performance. Is it as loud as 2021?
