Oh hi there! Welcome!
You chose the wrong car.
It's ok. I did too
Perfomance wise the car has SFA to give, but for more fun and enjoyment I added on BMW Performance exhaust and a hectic K&N filter. They have considerably improved my enjoyment of the car as well as the sounds. You get a deeper low end, change in engine tone at 4500rpm and a much more aggressive top end compared to stock. Sounds decent for a 4 banger, but still doesn't go anywhere in a hurry. Come to a meet some time and you can have a listen. Even if these mods result in power losses, the car is so slow that any side effects will be negligible and irrelevant in the scheme of things.
