Just finished front & rear floor, rear seat, sides of trunk, and pillars on my 05 STi. Took all weekend! Gonna do the doors and deck lid next. Already very noticable difference. Hardly hear my coilovers and the exhaust is much quieter. I can tell the only road noise is coming from the doors.
The loudest car I've ever had just got to a normal, if not above normal level of quietness.
Used Raamaudio's hardware. Very pleased. Thanks Rick!
