I would like to do a little noise reduction on my 2021 Cayman. On long drives 200+ miles it is a little tiring. Depending on road surface on coarsely paved roads it is load and at 75+ mph intake noise is a little higher than I would like. I do understand what the car is and could live with it but it would be nice to improve it a bit. I was thinking covering engine cover firewall and (car is mid engine)cargo area. Would dynamat or vehicle insulation closed cell foam or bonded accoustic cotton be what I need. I am providing link for vehicle insulation closed cell foam
