Real Iconic Sound for my X6 M60i

Hey everyone! So, I'm not trying to start a discussion about what people think of the Iconic Sound setting (I personally think it's insanely stupid and somewhat pathetic), but instead HOW can I get the real thing.

Ideally, I'd like to make this through software updates if possible. I don't want anything too crazy, just what would come naturally from an engine like this.

Full transparency, I know nothing about exhausts and making customizing to cars.

I ran my questions through Claude and these were the suggestions:

• Software/ECU Tune (Most Effective for Burbles) A "burble tune" or "crackle map" is the most direct way to get those overrun pops. It works by retarding ignition timing and allowing unburnt fuel to ignite in the exhaust on deceleration. Tuners who work with BMW include Bootmod3, RR, and various local ECU specialists. This can range from mild pops to full-on aggression depending on how it's mapped.
• Active Exhaust Settings The M60i may already have an active exhaust with flap control. Make sure you're in Sport or M Mode — the flaps open up and the character changes noticeably. Check your drive mode settings if you haven't dug into them fully.
• Aftermarket Exhaust A catback or axle-back from brands like Akrapovic, Remus, Eisenmann, or Armytrix will amplify what's already there. Some Armytrix options even have valve control via app. This paired with a tune is the sweet spot.
• OPF/GPF Delete (if applicable) The M60i likely has a particulate filter on the exhaust which muffles a lot of the character. Removing it (where legal) opens the sound up significantly.
• Realistically, a tune + active exhaust optimization will get you the burbles you're after without needing a full exhaust swap.

Are these real possible solutions that would work? Again, I know very little to nothing about making these modifications.

Thanks for any and all help!
