I think if I were doing it today, I’d use Dynamat. I just put some in another vehicle as sound insulation and it works great for that and is supposed to reduce heat as well. I put the Refletix on the gearbox side of the tunnel as it’s rather thick, but I think I’d put Dynamat on the inside. It’s very thin (but heavy), so I don’t think it would make the carpet look too thick. Not cheap, though.
