I wonder if you can get the factory part and add material to it.

The factory HV insulator cost ~$200 plus shipping plus the fasteners and is easy to install, 2mm butyl hood dampening and " Dynamat Hoodliner sound soaker insulation cost less than $200 and take some time and effort to install, but I expect it will be considerably better at reducing engine noise than the HV liner alone. My iphone8 app dB meter gives me a 51dB reading (phone in my hand while in the driver's seat) with just the 2mm Damplifier pro at idle just after cold start up, I don't have a before reading, but it's much quieter than before the install, so adding the butyl dampening would probably work fine under the HV insulator and make a good difference.

It's not a kit, see post 15.

Not worth doing that for that price! Also, that factor part is thin and fragile so difficult to manipulate without damaging it. You will also mess with the fit which is currently perfect.

My iPhone placed next to the cup holder showed a baseline of 30db without the engine turned on. It went up to 50-55db with the engine turned on but not moving. Driving it around in our street increased it to 60-70db. With the factory hood insulator, it seemed to be around 5-10db lesser. Let me see if I can remove the fasteners and do a more rigorous test. The fasteners are lodged in tight and are not budging (which is a good thing).

You probably need a panel tool to remove the retainers, you should also be able to install butyl sound deadner which is thin (1mm-2mm), being careful to leave the mounting holes exposed, then reinstall the insulator, although you may need longer retainers, you could use christmas tree retainers that are available at hardware stores, sold each instead of a package, they break sometimes when removing, but they're inexpensive.

I did a lot of research on underhood sound deadening, Noico costs less, but it isn't rated for heat that I could find, it's butyl but they use an asphalt based undercoating which would be questionable under the hood, I feared it may detach eventually, their website lacks any specs so I chose not to use it. Second Skin Damplifier Pro is rated to 450 and is made in America, I think Noice is made in China.

I want to make sure its not a fire hazard. Do you think the mats you applied are still less sound deadening than the factory. I know you dont have factory...but I dunno...200 bucks when a little labor on my part would save a ton. I do like the idea of stacking them.
