R231 sl500
I recently discovered that my SL 500 r231 facelift doesnt have valves in the exhaust for sport mode and in fact has a sound generator in the boot for sport mode / sport plus noise, to be honest i wish i never started to investigate making it noisier as now i know its fake noise i can’t unhear it as im driving 😩. I assume that an sl63 exhaust actually has genuine by pass valves or similar for sport mode which would give me what i want which is something very quiet for long cruising and something more fun when required.

So my question is can i retro fit an exhaust from a similar year sl63, has anyone done this?
