Go old school. Buy an older used vehicle and have it converted to electric. Something like a VW Bug? I see conversion cost $7k to $20K plus vehicle cost. https://electrek.co/guides/ev-conversion/
My son used to drive a Mini (I think it was a 2008) and bought a Fiat 500 Abarth a few years ago. The Abarth is a blast to drive but it is pretty loud. Seems that Fiat got away with having no mufflers on it at all. It only has a catalyst right off the turbo. His is a 2014 and one of the first automatic versions built. He tried a manual but he thought it didn't shift very well. The automatic can be run in manual mode and honestly, it's impressive. Even autoblips on downshift. If you run it up close to redline and shift it, it backfires pretty loud. He did wear the first set of tires out on it in about 10K. So he was having too much fun. Other than that, it has not had a single problem.
The turbo softens and directs the sound waves/gas flow in one direction so there is less noise. Backfiring when red line shifting indicated the mixture is too rich. The cat is igniting the rich mixture in the exhaust system at that time.. I assume he also has a BOV valve on the turbo?
If you want something unusual and quirky buy a Mitsubishi i-Miev. The one I linked to is only $5400, and located in IL. It might take you 2 weeks to drive it home...but you have to admit it's different!
I asked him and it has a BOV. Fiat calls it a purge valve. We looked at it and it's made by Pierburg. The PN shows it's on all of them and including the non Abarth turbo version. I found out my VW Alltrack has a Pierburg Blow Off valve. My wifes CRV had a blow off valve but it's called an air bypass valve. In the end, they all do the same thing. According to him, they all do this from the factory. So it was designed to do that. As for the sound, I am still amazed it has no muffler at all. I understand about the turbo but my two other turbo cars have mufflers and resonators. One is a 1.5l 4 cyl, the other is a 1.8. The Abarth is a 1.4l.
On my 1998 Jetta TDI (turbo diesel), I put an exhaust bypass valve that bypassed the muffler, and it was absolutely NO louder at all w/o muffler. Was a waste of money by VW to have one.
Mufflers and resonators and cats are for emissions and regulated by the govt. Now days they even have "Cat Fluid" for the diesels.
I had a 2000 Jetta TDI and when the exhaust rusted out I replaced the whole thing with one that had just a single small muffler on it and no CAT. It was too loud and I put on another bigger muffler to quiet it down. Even at that it sounded like a truck with the whistle from the turbo.
