Exhaust sound

Hello, I have a GT since recently and am satisfied with it. But what really bothers me is the “exhaust sound” during normal driving and easy acceleration. I read again and again about a great engine sound that the GT should have. But with mine the car just sounds like a small, old Corsa with a hole in the exhaust! It was like that, according to my wife, I wasn’t there when she made the first test drive with a proven at the dealer. I already had from the sound generator that many have jammed off. But mine is not loud and sporty, but just sounds bad! How does your sound sound like when you ride normally? In sport mode it sounds a bit duller and more voluminous. Not really sporty, but acceptable. Greetings
