My first question is how many square feet should I get to do a 1989 mustang GT hatchback(trunk, floor, doors)? Second is dynamat the best product? I know they have others out there? Also what thickness? I have a mildly loud exhaust and want to cut down on the noise. Thanks

 

you will be fine with dynamat. Measure out the trunk, floor, doors yourself to get the right measurements and give yourself a little extra just in case.

Welcome to the forums. I would possibly call the supplier as they might have exact measurements for you and possibly some templates!

 

A friend of mine used an off brand dynamat when he was restoring his bronco and it's worked well. Saved a lot of money that way.
