Well I got rid of my 2018 A10 GT and got a 2019 Bullitt. Why? I like driving manual, its more enjoyable. Is it slower, sure. Will go kaboom at some point but thats when I would upgraded the transmission. The A10 was fun and fast in a straight line but the rest of the time for a V8 Mustang it...
After a few days driving with just H pipe put in the car is plenty loud. I can only imagine what headers and more free flowing exhaust will sound like. The best is the deep rumble sound is still there just much louder.
