Damplifier Pro sound deadening and Luxury Liner Pro sound blocking materials are important for proper sound reduction in the EVO. Here's a couple more pics that give you an idea of what your project could look like:
* EVO #2: This EVO owner used Damplifier Pro and Luxury Liner Pro on the floor, doors, and trunk. * EVO #3: This EVO owner applied Damplifier Pro to the rear seat, seat wall, and trunk.
From the customer: "The car became painfully loud to drive at high boost and only 5 speed. Used MLV to cover the entire area behind the back seat into the trunk and a single sheet to cover the entire rear deck below rear windshield. I was REALLY impressed with it. A buddy got in and stopped mid convo on the freeway and said 'Wait, this is way more quiet than it used to be'" #SecondSkinForTheWin
