I think the newer Subies are more prone to whine. I have a 02 and installed the Kartboy front and rear with no whine at all. added the group n tranny mount and i got a very faint whine when cruising on the highway.
Has anyone tried installing the shifter bushings and doing some dynamat on the transmission tunnel? I know it's vibrating more or less the whole car (since all the sheet metal is connected) but I wonder if dampening the vibration at the source could help? I get my car next week, and on the test drive I took I noticed a bit of slop in the shifter that might take some getting used to... or fixing
And BTW, plan on installing a short shift lever and front/rear shifter bushings. The stock shifter is pretty terrible. Once the aftermarket parts loosen up, the shifting is butter!
My car is coming with the STI short throw (I didn't really want it, tbh, but since orders are closed it took a while to find a car anyway - I'm hoping that the excess cost of the accessories I didn't want will allow me to negotiate to get the ones I DO want for free)
I thought about doing the front shifter bushings from kartboy and using the STI rear bushing (hard rubber). I remember reading the STI one is a lot quieter?
Also, dang good job on the insulation! How long did it take you to strip all that? Would I have to take time off work?

Nice! I did this same thing with my '88 mustang. Hoping to get it a little quieter and smoother, but not sure if it will actually work. That thing is LOUD. I wanted to test it out there and see if it would be worth doing on the WRX. Please let us know what you think! My stang is still getting a few things done to it before it is back together so I don't have much of a verdict yet.
Now I can tell that most of the noise is coming from the doors, so they'll be done before too long. Its not shown in the picture, but I also hit the pillars and went a little further up the front foot wells.
EDIT: It took 1.5 days in total. I started the project with the intention of installing an amp under the seat. Next thing I knew, both seats were out along with the entire carpet "tub". It wouldn't have take so long if I wasn't running wire as well.

That is an impressive reduction! Did all the carpet and everything line back up when you were finished? Any thoughts on how durable it might be in the long run?
I like that you're doing this and I would definitely consider it on my car, esp if I ever do any stereo work (which I intend to)
There's something about taking the car apart and putting it back together that gives a sense of appreciation for mods you've done.
I used dynamat and it took a great deal of the noise out of my car. I actually put the group N trans mount back in after the dynamat and though it is a touch louder.. its not unpleasant at all. I'm planning some ccf sound deadener over the top of the dynamat but not for a little while yet.
fyi, dynamat does work quite nicely to take the high pitched buzzes out of the car. Especially in the hatch area. As mentioned there isn't jack squat for sound deadening from the middle of the front seats to the very rear of the car. NOTHING. Its a rattle can, so any/all measures you can make will have a positive affect.

SUCH IS MANGO!
Yeah, if you can do it all at the same time, absolutely; do it. You need to remove the console anyway to do the shifter (if your also swapping the shift lever w/ an AM short shifter). However, you don't NEED to remove it to do only the shifter bushings. But, I found it much easier to just remove the shift lever (need to take out the console), which frees up the shift linkage to be removed as well. The bushings are easier to install if you can take out the linkage. Otherwise, its super tight in there.
There's definitely an increase in tranny noise with the aftermarket bushings. Its only annoying when engine braking in traffic. The car sounds like its broken sometimes! But that's mainly because there's no freaking insulation on half the tranny tunnel. Its not as bad since adding the duct wrap.
