[panthera]

Hi,

I have a 2021 430i B48 G22 with a wired OBD connecter that can goto my iPhone or MacBook.

I want to add a burble tune or something to add some depth to the exhaust without heavily modifying it.
(I don't want to void the warranty, and I want it something that I can easily revert to stock before I bring it in to the dealer).
I am aware of the risks.
What are my options? I was looking at MHD flasher... can I use this? Or what other apps out there work for what I am trying to do?

Any help is appreciated! Thank you
