These HushMat Ford Mustang sound deadening kits provide you with the correct amount of material to completely cover the floor, firewall, trunk, roof, doors, and tunnel of your vehicle. Our Mustang sound deadening kits feature the HushMat Ultra material which is the only sound deadening on the market that is approved by the SAE for use in new vehicles. The HushMat sound deadening for your Mustang does not require any special chemicals for prep or tools for installation. Simply vacuum the surface and the product will simply peel and stick. HushMat is rated from -30 to 550 degrees Fahrenheit and will maintain its performance and adhesion through that entire temperature range.
