Sound dampening engine noise

[Stacey in SC]

the killmat has his own adhesive backing. I just cleaned the surfaces before applying. I did replace all the exhaust gaskets and hatch seal gaskets.

I’m looking everywhere to find the gasket that was used on a lot of threads up until last year (the Duck garage door gasket). Is that what you used? Seems hard to find.

I used regular closed cell foam gasket with the adhesive backing. You can buy it at lowes or order it through amazon.

Riveramx, your videos are very encouraging. Got to get the sound under control in my 2007 SX210.

Yesterday I was cleaning the muffler box preparing for sound insulation and found something interesting. When using a jet of water from the hose if I spray the back of the engine firewall there is little to no vibration transmitted to the deck. If I directed it to the underside of the deck there wasn't much vibration transmitted, same for when directed at the mufflers themselves. However if I directed the spray to the far right and left on the flat panel in the muffler box at each side you could hear and feel the resonance vibrating the deck. Plan was to just use a foil faced foam type insulation as the butyl stuff seems to be more suited for resonating metal panels but after finding this I ordered some butyl mat to cover those before a layer of foam insulation. My guess is that these fiberglass panels for really thin and act like a speaker cone, this would also transmit a lot of sound into the seat storage areas. Will be working in it this week and see if it helps.

This one is just a little bit wider than the 2".

Robot or human?

Seems to be in stock.

Do you have a picture of the top hatch of your engine compartment?

I was curious to see what your gasket install for that closure looked like? Also, did you remove the factory foam, install Kilmat, then put the factory foam back on the Engine compartment lid?
