My 172 03 is totally standard.I would really like my car to sound how it shud sound. I dont want an exhaust yet,just an air filter or induction kit thats going to give my car a roar and some extra bhp. At the moment I could be a little 1 litre coz there just aint much of a tone to it, although it sounds ok when pulling away in 1st.I do love my car.
