Description

The Hushmat Trunk Sound and Thermal Insulation Kit 682804 is a sound deadening and thermal insulation solution designed to treat the floor and rear quarter panels of a vehicle's cargo area. This kit aims to reduce aftermarket engine and exhaust drone, road noise, and vibrations, while also diminishing heat transfer from the engine, headers, exhaust, and catalytic converter. The product is made in the USA and is described as being lightweight and easy to install, requiring no surface preparation. HushMat claims to reduce noise levels by up to 15 decibels and states that their Ultra material is the #1 rated material in performance, as designated by multiple independent studies.
