They’re not modifying the ECU, they just feed it false info through the sensors, so it doesn’t trigger a CEL. Same as the JB4.

We can change back to default any time and there is no mark of changing anything in ECU. There is no tunning just few clicks to get sound back. So this cant be reason to loose warranty.

Its every owner choice. You can have real M5 with pops and bangs or nothing.

As well as CEL was not triggered because factory parameters inside firmware were switched off manually as well before the car was started.
Can I contact you mighty to discuss this by email.or text thanks

Aftermarket exhaust and flash to kill the 🍿 but you know the risks with this, especially to simply remove the pops. F10 M5's with aftermarket exhaust sounded amazing and no 🍿.

I went iPE cat-back on my current F90 and simply close the valves when I'm over the bangs and pops.

My car in Sport + Valves open sounds insane when in WOT but the pops literally scares the shit out people.
