Yeah. I think they are thin enough that they essentially become speakers.

Noise disappeared after installing G-N engine mounts. Sounded like transmission was about to fall apart prior to installing the G-N engine mount. Not sure this would work for everyone, but it surely did on my car...

Huh, I have Group N mounts in my car (all three) and was considering swapping out the trans for the stock mount to see if that helps.

Definitely didn't for me.

What do you guys recommend for a clutch and flywheel setup that will be good for a setup over 300tq and around 275 whp? I'm tearing apart my motor again and want to ditch my Exedy Stg 1 organic clutch and ACT 14 lb flywheel because the noise drives me insane... I want to replace them with noise free parts.

x2 Lots of information here, but not many suitable alternatives. If we are running higher than stock power levels but still want a quiet ride, what are we to do?

High HP and quiet don't go in the same sentence. Stock clutch/pp/flywheel are the way to go if you want quiet. I learned to live with it (stock flywheel, ACT HDSS pp and clutch).

Check your rear diff mounts (the ones near the sides of the car). The plates on the bottom of mine were bent from someone using them to jack the car up. This allowed the diff mount bar to touch metal on metal with the mount, instead of being isolated by the rubber. Once I fixed the mounts, my noise was gone.

You can have.

Yes, it sounds horrible for the past 20k miles I've driven mine LOL.

The alternative is to make sure that every bushing between the rear diff and the shifter is not any upgraded urethane product. That will only reduce noise, not eliminate it. The 10 or so pounds of missing material from the LWFW is part of the issue as it has a dampening affect. The other part is that materials on performance LWFW tend to be harder metals, thus you have a greater transfer of sounds.

The sound is transmitting up through all the connections to the body and there isnt a lot of additional sound deadening material in the floor, tunnel, and spare wheel well. Insulating those might help.

Its hard to believe that the sound isnt due to something about to fall out under your car.

When my MY00 Impreza 2.5 RS needed a new clutch just beyond 100k miles I installed an Exedy Stage 1 clutch, ACT Lightweight flywheel, new master and slave cylinders, and group N tranny mount and it was awesome. I've never heard any noise out of my set-up like i'm hearing in some of these videos you guys have posted. That does not sound healthy at all....

Question: How can I sell my car to someone with this noise happening??? Me: "Don't worry - it just SOUNDS like the transmission is going to explode. It happens to lots of people with these cars, but it's not going to be a problem for you."

I would really sound like I'm selling snake oil.

Yep, that was the only thing driving me to get mine replaced. I can put up with the sound but if I have to replace the clutch to avoid scaring off buyers then I may as well do it sooner than later.

I don't think I would buy a car making this racket without first hand experience with it.

Right - so I'm screwed. I can pay to replace things or I can gamble that someone will take it.

So it seems like the sound started for most everyone after a clutch or flywheel change. I think I am getting the same sound but only I havent changed anything. Still on all orignal OEM stuff. It just started after a kinda hard 3rd gear pull one day and when it was reving down is when I got the sound. It does not do it all the time eather. Any of u guys have the sound just start one day or is this something else.

Glad I found this thread cause I was seriously getting worried. Just got a ACT HD with organic disc and a Streetlite flywheel. Damn, it does sound like a bag of rocks but I can deal with it.

I had a new OEM flywheel and Exedy HD clutch installed, and have some bad deceleration noise at 55mph at any gear. I thought it was something loose, not tightened. Sucks it could be the clutch/pressure plate design.

I have the same set up and noise. Only way it's going to go away is to put everything back to FACTORY OEM (not oem replacement). I just turn up the radio louder and don't notice it anymore. Next time I decide to kill an afternoon working on my car a factory OEM clutch is going back in.

Default vibration during acceleration and random times

I am the owner of a 2005 sti 360whp, I also own a 1998 subaru legacy wagon with 233,000 miles on her and she has a vibration during acceleration. Also just random times the whole car will shake. Not sure if its i need to replace my tranny or front diff? or replace all my bushings? anyone have any ideas. I just drove her to Colorado from Boston with only a half hour break and she was perfect the whole times except for the vibration, always at 80mph+ and during acceleration. I want to keep her cause I know I could get 400+K miles out of the motor and I can do a tranny swap in 3 hours. HELP!!!please
thanks

Im having the same problem just like the rest of the world here... Sounds like a baseball card in bicycle wheel spokes... Just got my 03 sounding like this.. Guy said he had the clutch done by a garage who prob used an exedy kit. Sounds like shes gonna blow up but runs and drives fine? Its gotta be the clutch and springs. Im gonna have to put an oem one in, theres no way Im trusting this ***** sounding like a box of rocks bouncing around... It almost sounds like one of the fingers on the pressure plate is bent in or something and is nipping the clutch maybe? Dont know, gotta tear it open and see..

I'll add a bit to scare you guys..

I had the noise too after Fidanza flywheel install.. Knew it was going to happen.. No biggie - not my first rodeo... Also knew I was on borrowed time with the trans (power - trans only had 30k on it). Weeellll.. Did my drag passes on it.. Survived.. Drove the PISS out of it for the next 10k miles or so.. But for the last couple K I noticed that the noise on decel was getting progressively louder / gnarlier.. And it got progressively louder and louder.. Untill one day.. BAM!! Bye bye third..

Ok thats all.. Now you will all expend way too much brainspace on listening to see if that noise is getting louder...

Cheers!!

On the side note...I have noticed that noise completely disappears if tire pressure drops below 30psi.

Yo this topic is SUCKS; wish I didn't have to forward it to the company that sold me my exedy clutch. I just put in an exedy stage1 clutch. My stock/original clutch on my 02 wrx had 130,000 miles and the throwout bearing was getting loud. Instantly after putting it in--it made the same damn noise. NOT a natural one. EXACTLY like Caterpill's sound, exactly. Yes, I even tried to record it, but it's difficult to hear. I can't live with the noise so I'm swapping it out with a stock clutch ASAP. Just spend a grip of dough on the clutch, flywheel, radiator, timing belt, and tail-end tranny rebuild and don't need this.

Does anyone know if there will still be chatter with an OEM dealership clutch, but using an ACT 14 lb. flywheel?

Chances are pretty good that you WILL get some noise. I've ridden in a few Subies with just the lightened flywheel; they aren't as bad as the non-oem clutch replacements, but they do make noise/chatter.
