Exclamation Burbles on Locked '21

Just wondering how I would get some burbles with a 2021 locked m340i. I heard that a muffler delete would grant me some? Just want some more input before I actually pull the trigger. What would yall recommend?

Thanks

Garage List
Downpipe will give you the most Burbles without a tune.
Muffler delete or aftermarket exhaust can help but the most will happen with a new downpipe.

Hey there! I have a muffler delete and an AA dp right now. It doesn't burble at all, just gets a few pops here and there but nothing crazy. Only way to get burbles is through a tune, which requires a femto unlock.

I had just a muffle delete for a few months and I'll say it's very obnoxious and full of drone with no popping. 100% would not recommend it (bought the car with it). I ended up buying the alibaba valved exhaust and am just waiting to install it.
