Ok as we all know our trunks run very hot. The lack of insulation in that are leaves much to be desired so I'm going to go off on a limb and try something out.
Anyone ever heard of two companies, 1 is Thermal Protection Inc, they make a gold and silver foil that is designed to reflect heat. Another is a company called Koolmat. This product is akin to the foam insulation we have on the driver's side firewall. Yet offer better sound deadening and heat protection.
Now does anyone know the following? Dimensions of the two firewalls, and Dimensions of the area above the mufflers? I would like to give things the benifit of the doubt so we'll see how things go. Least it's something vs nothing on the heat/noise front. Anyone know the best places to put sound deadening material on the interior??
