Default Sound insulation

I have removed the old sound insulation from the engine bay and trans tunnels. I am asking for any recommendations for an easy to apply after market substitute.

What are you trying to accomplish? Sound deadening, or simply blocking heat?

Removed the stock sound/heat deadening material as it was worn and falling apart. Instead of buying expensive replacement pieces through the dealer Iím looking for other recommendations. This is a more track oriented vehicle and not much street driven.

Maybe some sort of spray would be easy to apply? As nd maybe not weight as much as butyl or other material? IDK

i don't think the aluminum piece between exhaust and drive shaft is for sound deadoning. it's primary purpose is a heat shield.

Default Re: Sound insulation

Ok, I assume you're talking about the sort of "fabric" that's attached under the trans tunnel. Try looking into various forms of Dynomat or similar. They have different formulations for sound, heat, etc.

The problem with dynomat is I donít think itís designed for the amount of heat that it will be exposed to in that area. And the OEM material is likely fireproof (it has fiberglass short strands in it.
