This sounds pretty close to my X4M40i with the N55. Sounds like what MHD created is not the same.

I also am wondering if they added the hard engine break that goes with the sound. In my X4 it pulls you back when you let off the throttle. I find it to feel much sportier than my 435. I wish I could this over the "Brap" sound.

Yeah and not much either. It's almost indistinguishable from the normal sounds and even more so if you have burbles on. It's hilarious.

But if somebody complains about the sound not being aggressive like on the other videos, keep in mind that it's on stock exhaust system + high flow cat.

I want to hear it with catless + turbo back exhaust system.

Thomas590 · 02-07-2022, 04:12 AM

Anyone yet tried with catless?

YAYYYYYYYY can't wait to flash this when I get home. I'm catless, resonator-delete with OEM muffler. I'll see if I can record some video soon Thomas590

I flashed my car and went for a test drive, but did not hear any braaps...

Yeah, I already had loud burbles, this did nothing noticeable at all.

I've found 5-6th gear pulls causes enough boost to create it

Hard to hear on the video as my phone was in the cup holder but I'm starting to hear it now (short brap setting) I'm catless with the exhaust valve open to bypass the resonator and muffler.

Any chance you can try the long brap setting + record it outside please.

Since you are catless + bypassing resonator and muffler it should sound similar to what we could see in the first video.

Yup, looking forward to see more catless trubo back exhaust clips

That's what I found so far:

Mine sounds really good the nastyness it gives out on gear change sounds savage

Catless into standard box pretty high boost probably add to the sound

Savage eh? 😆

aacabriolet · 06-20-2023, 04:26 PM

Anyone managed to get this on BM3?

aacabriolet · 07-04-2023, 03:22 AM

Here's a good video demonstrating the stock M2 overrun/brap.

So now how do we get this on BM3? Any tuners able to do this? Anyone managed to replicate this properly? The MHD seems alright but not quite the same. I guess I could sell BM3 and go MHD if I really want.
