Default Re: Sound deadening Q ?

I installed a cowl insulation kit from QuietRide Solutions on my ‘31 roadster, and also installed a firewall insulated panel available from most vendors. I also used dynamat on the underside of the floorboard above the muffler, and covered this with 1/16” aluminum metal sheeting. Insulating these areas made an immediate and very noticeable decrease in noise and heat inside the car.
