I have yet to buy my WRX (looking for an '03 wagon) but I might as well ask my questions now. Has anyone put dynamat, raamat, fatmat or anyother sound deadener all over your wrx? I would like as little road noise as possible, so I am planing on putting Dynamat extreme under the entire floor, all doors, the wheel wells, and the 5th door (remember, wagon). Has anyone done this? If you have, did you notice a large decrease in road noise? Anyone with wagon specific help would be great too, but I would love to hear from you sedan owners as well. Thanks.
