Exhaust bypass on f10 M5

Anybody played with the idea of the exhaust bypass valve. I've seen systems on AMG's and various other cars, for off-road use only of course. But it would be a toggle switch that would be a side exhaust exit just aft of the downpipes. Real loud, no emissions.

Just curious what this would do to the car? For $8k on an akrapovic system I think my fabricator could mock this up nicely, with a nice button in the cabin to toggle between the two setups.

I assume this would throw a check engine light but would the car still run ok?

Thanks in advance.
