How hard was install and did it make a difference in road noise since it absorbs bumps better? I have a set on order.The rpmtesla noise reduction kit is easier to apply, cheaper and gives immediate results, especially when supplemented with the additional rubber seals on the rear hatch but mostly helps on road noise, wind noise, and eliminating the rear hatch buffeting and hatch movement (assuming the hatch adjustments are also done).
The noise deadening material (butyl and foam) are more for reducing the low-frequency booming on uneven road and the resonance from the car’s body and frame, especially from the rear (fenders, sub trunk, hatch) where there’s a significant portion of the car that uses thin sheetmetal and just resonates badly; and also reducing some external noise from entering the cabin. Doing this requires some disassembly and tiring effort with the roller and figuring out where and how much to apply, but if you’re desperate to reduce the booming and improve cabin comfort, definitely worth doing.
I should also mention I have the Mountainpass Comfort Adjustable Coilovers which have dramatically improved ride comfort, even on the 21” uberturbines, and overall car driving dynamics; while these have soaked up the bumps well, addressing the noise issues was still necessary for me. I don’t think there’s a more comfortable Model Y on 20 or 21” tires on the road than mine
I tried their kit, mainly to keep the channels around the hatch cleaner but ended up taking them off. I prepped well but the seals would still come loose in places and I got tired of re-applying them - YMMV. I didn't notice any noise reduction.
Sorry I should have been more clear, I meant the MPP coilovers.With good surface prep (alchohol wipes) should take about an hour and easy to do; watch the install video on rpm’s product page. I don’t think it absorbs bumps better, instead provides better sealing, and likely limits movement with the doors, hatch and hood. Noticeable road noise improvement- see @MY-Y post Noise reduction kits worthwhiled?

what about the Retractable Cargo Bay Cover from RPMTesla, will it works? since i see so many SUV with this cover on the trunk and no noise issue.Has anyone tried the RPMTesla trunk "bucket" inserts? I'm thinking I might try them, and depending on how snug they are, placing a layer of felt/fabric on the outside of the inserts. It just might cut down on the dreaded low frequency boominess, while creating a bit more function for the trunk.
I made my own to test it. Took a cardboard box, broke it down and shoved it back there. It fit perfectly. I still felt the ear pressure so I figured a real one wouldn't help.what about the Retractable Cargo Bay Cover from RPMTesla, will it works? since i see so many SUV with this cover on the trunk and no noise issue.
Hey Scott,Of course, my case seems to be different from most people in that I feel it with the car sitting still and the door open.
Noticed this today: when standing still, there is a low frequency vibration (probably ≤ 40Hz) lasting about 2 seconds, then cycling through every 5-10 seconds thereafter. It seems to originate at a structurally-sensitive point that vibrates the frame of the car. Reminded me a bit of a sub-woofer in a car parked next to me.
Thanks for the info. I will go on the Model 3 forum to see if I can find that.Hey Scott,
I think the Heat pump's a likely culprit for the sound you're hearing while the car's not moving. There's a thread on this on the Model 3 forum and heat pump seems to be the consensus. I can't remember having heard anything similar in the Model 3 pages before the Heat Pump was introduced. If the Y is particularly resonant at these frequencies, it could easily explain how the Heat Pump and Back hatch are both triggers for the same issue. (ie, they introduce a 30-40Hz signal that is amplified by the body resonance of the car)
Sorry, I can't find it on the Model 3 forum. Could you or somebody else post a link?
I'm desperately looking for any advice anybody has.
I lined the outside of my rear bucket with butyl - it didn't make much difference. The boominess isn't from the bucket area.
Thanks. I don't know if it is the same as mine. They are all hearing something. I just feel a pain in my ears.Noticed this today: when standing still, there is a low frequency vibration (probably ≤ 40Hz) lasting about 2 seconds, then cycling through every 5-10 seconds thereafter.

HI @MY-Y and @gundarx , i like to know is anything like PE Foam will stick and able to tear-off ? i picked up my car on Mar and im afraid this will void the warranty. My wife and i can hear that noise on driver seats and willing to fix it since tesla service center unable to fix it at this moment.I ordered the stuff from Amazon you mentioned and did something similar. A few thoughts.
1. I put the foil butyl on the outside of the trunk bucket. It allowed me to cover the bottom as well.
2. I didn't put butyl where you did on the crash supports (shown in your video) because I think it will significantly impact their sliding in during a crash.
3. I put both sound sheets inside the 1/4 panels. I think this was the main benefit.
Overall, the low frequency is a little better. The road noise is quite a bit better - so much that I notice wind noise now. I just ordered the two RPM Tesla kits.
