How can I achieve this exhaust tone? I am looking for exhaust recommendations but I would like to keep my warranty so no downpipes.

Depends where you live, my friend, as emissions and mod regs will determine the extent of your adaptations. But a starting point would be to get Akra's cat-back full titanium system (asssuming you don't have an OPF to negotiate). But the car in the video may well also have some kind of ECU adjustment (fuel map) to make crackles on the static rev sound that prominent.

It definitely has catless downpipes installed, you can hear from the whistle and an ECU tune

Buy a cat back exhaust since you won’t tune or install down pipes due to warranty. Any valved exhaust will be reasonable in Efficient and loud when revving or getting on it in Sport Plus. Titanium exhausts are thinner walled and lighter and sound a little more exotic than stainless but cost more. There are also unmuffled and valveless exhausts if you are in your 20s, want everyone to look at you and don’t mind your neighbors complaining.

I wanted to keep my OEM downpipes and went with a titanium cat-back exhaust and it's not this loud. At all. The downpipes are the primary restriction.

The crackles sound terrible innl my opinion. I'm going catless and I'm removing pops and bangs. Burble sounds great but pops and bangs are rice.

Yes, cars are like mini mufflers, but if the OP insists on keeping his cats then he is limited in his options to a cat back. A full titanium cat back — meaning downpipes back not axle back — will be the loudest muffled and valved exhaust. If you need louder while keeping the cats, consider an unmuffled exhaust without valves.

I have pops and bangs or burbles or whatever on the default setting in my tune. I could make them louder but the default is more than enough for me. Most of my driving is in Efficient mode where they are minimized. Don’t need Sport Plus driving around town or cruising in normal highway traffic.

Here in the UK we have to contend with the additional muffling effect of the OPF which sits after the cats. But in my case, I'm hoping that the slip on (valved) axel-back that Akra have designed for the F90 will give me a better note, both at idle and under load, even while retaining the OPF. I do think though I'll also have to map some of the burbles and crackles back in (they were mapped out on the stock ECU tune from around late 2019), when the time for fitting the exhaust comes. I don't want gun-shot bangs; but I wouldn't mind a bit more warble-'n-pop on the overrun and when lifting off.

+1 for titanium Akra with Keller down/mid pipes! Here’s mine, bad phone mic though sounds way more throaty/aggressice in person.
