Interior Thermal Protection Under Carpet

[AB69Z]

I have applied Raptor liner to the interior floor area of the car and have the DynaMat Extreme ready to go on. Do I need thermal protection on top of the DynaMat before the carpet ?
i was thinking of the DEI product
Or spraying on the Lizzard Skin over the Raptor Liner then the DynaMat then the carpet.
I'm worried as my exhaust is tucked up very close to the floor
