actually if you just put the exhaust on, it will change the sound. it will de more of a drone. but really isnt that loud that is if you have the stock exhaust piping on. i know cuz i had an axel back and isnt loud except when you accelerate. and thats with out the silencer. but if you get a catback exhaust system it will be loud as hell. am you will most likely get pulled over for that but just the exhausr i doubt it. i run by cops every day and not once have i gotten pulled.

as for the id if it doesnt have the name on the exhaust can it usually is a no name ebay brand.

and its cool that you as a dad would put an exhaust on your daughters car. my dad hate my car. too low!!!
