BMW 135i or 335i Exhaust with MHD Burble Option
With MHD’s latest release of the “burble” exhaust option, I had to try it out. You only need a few things to make this happen.
Simply download the app, plug the flashing cable into the car and connect the OTG cable to the tablet. Then you can flash a map with your desired burble settings.
I have the burble option set to full aggressive. I have catless downpipes and a full catless exhaust with only one muffler. Take a listen…
