so i have an 09 fit sport AT. i was wondering, if i get an exhaust will it sound different than a manual fit sport? since i have a sport i can go into manual mode; would it make a difference? thanks

 

Switching into Sport mode will not make your car sound different. Getting a new exhaust will.

Edit: But I should stress how much $$ you're spending on just making it sound different (not necessarily better) with negligible performance gain.
