I have seen some options out there,
1. Stock 2. After market a. AA pad b. Rix914parts- modern material, light weight c. dynamat d. 914rubber pad. 3. -others?? Also in the cab, the rubber sound deadener( I assume this was only for sound or vibration, since it is rubber I doubt it did much for heat) - I pull this out it was stock and am trying to decide if I should put it back in again or do dynamat or something like this on the inside firewall before putting the backpad back in |

For the engine bay you will want something made to absorb sound first, block heat second. Add a sound absorber to the bottom of the engine lid.
For the inside, start with the aluminum backed butyl rubber sound mat that will reduce sound transfer thru the sheet metal and block heat. You can put the stock rubber piece back in but it won't be as effective anymore. Add a sound absorber like the foam back pad or carpet. Also adding jute under the carpet will reduce sound reflections. Lastly, significant engine noise bounces off the street to under the seats, so do extra back there. PS. make sure the rear window is well sealed. |
