What is the best way to sound-proof my mk4 hatch. I am not looking to sound-proof the car to enhance audio quality, I would just like to block out a bit of engine noise and exhaust drone which can be heard when inside the car. I do not have any sound proof matt on the underside of my bonnet like so models, i suppose this would help but the noise that annoys me is the exhaust drone. (although i would like to keep my remus cat-back & stainless backbox)
I know alot of people will recommend the likes of dynamat etc, but i am not soundproofing for the same reason in which dynamat is designed for....so i am looking for something more specific to blocking noise rather than reducing panel vibration.
