Dynamat Xtreme 36Sq.Ft Kit Bulk Pack 10455 46137-VipDynamat makes hot rods cool and quiet! Its sound deadening liners, mats, and materials reduce interior engine and road noise, eliminate vibration, and reflect heat. You get a quiet, cool, and comfortable ride plus maximum acoustical performance from your sound system, too! That's why professional car builders like Chip Foose and Troy Trepanier won't build a project vehicle without Dynamat sound deadener and insulation. Your car will be quieter inside and much more enjoyable to cruise the town in!
