Ford ZX2 cabin sound dampening (WIP)

My car has a loud exhaust and a lot of road noise. Its pretty annoying and i decided to try and fix it.

*Not actually my car but its the same model color year ect...

Conclusion:

There are a bunch of ways to do it but i guess the best is to cover exposed metal with some sort of sound dampening material. Wheel wells, trunk and door panels are the important parts. Name brand material is dynamat which is pretty expensive. The alternative is a roofing material which is a tar based flashing with aluminum on one side and come in rolls. Its self adhesive and supposedly works as well as the dynamat for a fraction of the cost. I picked up two rolls of this at home depot for $35.

Results so far:

Road noise and exhaust noise are significantly less! Installation was easy with the use of a heat gun to soften the material a bit and it stuck well the the exposed metal. Getting the correct geometry was tricky in places but its cheap so i just figured more was better than less and overlapped some spots. I also put some of it to the rear deck because i had it all apart from replacing my rear speakers which I think improved the sound a bit.

I still have to do the from wheel wells as well as the doors. Probably going to spray rubberized undercoating on the insides of the wheel wells to reduce road noise even more.
