Just purchased an 06 white sti. the owner of the dealer was a nissan enthusiast, so i got the car for 23k and they gave me 18k for my car. the car has 25k on the odo. i could use some help on what some of the mods are. i know it has a cai, but the exhaust sounds too loud to be stock, but the tip looks stock. so maybe i can meet up with some people and they can help me out. thanks guys.
