Looking for the best sound deadening kit for my 1968 Mustang (Cobra Clone) trunk. I have a two year old daughter and am looking to " quiet it up" on the inside of the car

I need a material to replace the back panel of my 1966 mustang's trunk (the panel behind the back seat). Would this be my best bet for replacing it or is there an actual reproduction panel that I can install?

Asked by: Dingo
This is the original style reproduction panel that you are looking for part #C5ZZ-6545728.

I've just fitted a cold air intake and performance exhaust (axel back) to my 2014 5.0. It's excellent but I need to tone it down a few decibels inside. I'm thinking some acoustic insulation in the trunk, would this be my best option?

Asked by: FluffyP
Absolutely! That is exactly what this kit is designed to do.

Asked by: maddog 101
It won't fix the problem - just make it less easy to hear when you drive.

In trunk I can see the back seats and the springs, is there something to put there to cover it. Also something to stop exhaust smell from coming in the car. 1966 mustang coupe. And very noisy 302 engine.

Asked by: barbie
Dynamat is probably your best bet for both sound isolation and to keep smells out. It will work better for the sound than the smell, but will help with both.
