My wife came home with a 2004 WRX today that we decided to purchase. It has 10,000 miles on it. Anyway the car is slightly modified. I noticed it has an aftermarket mufler which sounds good. The SUBARU letters were removed from the trunk which is nice too. HOWEVER, it has a GReddy blow off valve installed. The old parts that were removed to put this on are in the trunk in a box. I hear theese BOVs are bad for the car. It makes a loud hiss when you shift gears. My question is, do i remove the BOV?
We both love the car. Its BRIGHT blue with a 5 speed and a sunroof. It also has the "cold weather package?" which means it has heated seats.
Anyone got any idea what I should do to the car? It will be a daily driver and all around fun car.
