I have an issue coming form my 03 WRX there is a weird noise coming from under the car only when the vehicle is going between 45-60 mph. I noticed this after I switched from my regular stock intake to the SPT intake. A shop had told me it was the intake. My friend a Subaru specialist told me it could be the wheel bearings, tranny or driveshafts but everything is ok. Any help would be appreciated. Thanks.
