Exhaust recommendations

I recently picked up my first bike; a 2024 MT-07, and I’m loving it. Though, I’m looking to put an exhaust on, which seems to be the most difficult choice. I’ve been looking at the Mivv Delta Race but I can’t seem to find where to buy it (I’m in the US). Might be a stupid question but, where would I buy it? Also, if you have any other exhaust recommendations let me know, I’m open to changing my mind. (Preferably under $1.5k) thank you all! Ride safely.
