I'm really tired of how loud my car is, especially with my exhaust so I'm wondering if anybody has used Dynamat lining in their Civic and how it performed for them. I understand it can add about 100lbs to the car, but I just drive my car daily and am not going to ever take it to the track. Even when I get a swap done, it will be done for my own personal enjoyment, not for racing. Point is, the weight doesn't matter. I just want to know how quiet/driveable I can make my car. Thanks
