Heat had not been a problem with my TR4, but at 60 m.p.h with the hood installed and the windows up, the resonant frequency of the stock exhaust system at 3000 r.p.m. generated a loud booming sound in the passenger compartment. (The car lacks overdrive.) Applying Dynamat Extreme > Automotive Soundproofing & Heat Control | Dynamat < to the floor and firewall and covering it with a layer of Dynapad > Heavy Duty Noise and Heat Reduction | Dynapad | Dynamat < in place of the stock jute pad yielded a noticeable reduction in that noise.
