2003 accord 3.0L v6 4 door general upgrade help!
 

hi, so basically i have a 2003 accord 3.0L v6 4 door. it has a k&n CAI and thats it as far as aftermarket. (love it btw) now, obviously its kind of a mom car haha but is there anything that would be worth changing/upgrading to make the car any faster, or get better gas mileage? ive seen people put headers and exhaust on 03' accords, but i dont want to act like my 4 door is gonna be on the next fast and furious movie. any help would be nice. i think it is kinda fast for a 4 door and it would be cool if it sounded better or were faster, but i dont know if this is just wishful thinking. thanks!
