intake/exhaust upgrades in s. fla.

hey,

just wondering if there was a place in s. fla. (ideally in miami area) that anyone could recommend? i'm looking for an intake & exhaust upgrade-b/c thats all i can afford i don't want anything too loud and nothing that hangs too low. i don't have any plans to lower the car, either. but, i'm hoping to see what the different options are like in person. thanks in advance for any help!

peace.
