I have been thinking about using some undercoating on the stang, underneath the stang, to help keep the road noise down. Has anyone done this, or know how well this works?
Seriously, you should just learn to live with it. I used Dynamat on the whole trunk with ONE layer only and that alone was 30 pounds. I couldn't even tell a difference in noise afterward because you're supposed to use like 2-3 layers. so if you do it right, which is 2-3 layers for the whole car, then you're looking at over 100 pounds! that will kill your performance.
yeah thats what I found on the old 5.0 I had, I used a crap load of dynamat on the floor/hatch and I really couldnt tell. I did not do the doors however and I hear that they make a difference. Either way I was thinking about the undercoating because it looks clean (when done right) and if it makes it quieter then thats even better. For the record, riding with a woman in a loud car is even more annoying than the road noise..."Why is it so loud in here? Is it supposed to sound like that?"...shut up woman lol.
