i have 2 questions:

1. does anybody here get white/grey smoke come out of their exhaust when they initially start it????
this doesn't happen all the time but probly 70% of starts... all i hav is cat back on an 04 wrx??
i initially thought turbo but it doesn't do it on boost, just when starting the car

2. i'm getting a whining noise when im travelling between 60 and 90km/hr???
i thought diff, purely because it only does it at a certain rpm which should mean something mechanical???? correct???
but subaru are telling me it's my tyres and i would hav thought that if its tyres it would do it all the time..

thoughts??
