2017 and newer V10 plus reliability & side question about exhaust options

I'm currently shopping for a fun car (finally after 10 years of family cars and trucks!) I believe I have narrowed it down to leaning heavily toward a 2017 or newer V10 Plus. My question is, for those of you who have owned these wonderful machines, how has the reliability been and have you seen any specific things to look out for? I would be putting roughly 4000 to 5000 miles a year on it.

My other question is: What aftermarket exhaust options does everyone have and what do you like/dislike about it? I Youtube videos are one thing, but hearing the car in person is a whole different animal. This would strictly be a fun car for me to drive on nice days, so I'd like it to sound aggressive to increase those smiles per gallon!
