Hi all

i have a frame-off restored '65 coupe with a 365sb 4.11 rear, and sidepipes.
The car is somewhat loud, especially when cruising down the hwy at 60 or 70mph. I love the pipes and don't want to get rid of them because of how they look on the car.
I used to be involved a number of years ago in the car audio industry so i'm familiar with various sound damping products such as Dynamat. Dynamat is a product that is approx 1/8" thick and you lay it out on as much of the metal surfaces on the car as possible such as the interior floor pan under the carpet and in the doors behind the door panels. This gives two advantages. It reduces resonces on the metal to help reduce or elimanate rattles and vibrations plus it reduces outside noises such as wind, tire, and engine noise.
I was considering adding this to my car but I'm hesitating for one reason. To put it on it adheres to the metal faily well and after it's been on for a while it's VERY difficult to remove. I don't go through NCRS judging so I'm not concerned about getting points for loss of originality, but I AM concerned about the future in case I ever go to sell the car. Do you feel that adding something like this will negatively affect any value on what is otherwise a fully restored and original stock car (except for the sidepipes which were added on by a previous owner)?

Barry,

The floors in your '65 are fiberglass, not metal. There is already lots of sprayed glue on the floor that holds the factory jute material under the carpet.

gee, i feel dumb!! I knew that but while thinking about putting the stuff on the doors my mind automatically went to the floorpan because this is where we always put it on in other cars. I didn't stop to think about how my car was actually contructed compared to other cars i did this with.

Same question remains though even if I only put it on the doors.
will it affect the value of the car in the future do you think?

I'm actually not sure if there is any factory jute material on the floor of my car at this point. I have only had a small section of the carpet up but didn't see any so I'm thinking that the previous owner who did the restoration my not of put jute back down under the carpet. If I look more and see there isn't any at least I know I can add that to help reduce some noise.

BTW, you must be laughing at me complaining about loud noise in my car from only a stock SB motor compared to what i'm sure your car will sound like!
LOL

I doubt it would hurt resale much, if at all. A non-visible item like that would be relatively easy to remove without leaving much evidence.

As for noise, when I used to drive it, I always wore earplugs, for my own sanity. I will again. :crazy

now that's funny!!
I hadn't thought about that advantage before. With the sidepipes, it IS very difficult to carry on a conversation so I don't get blamed for not listening or not paying attention to what she is saying when we are driving in the car as we tend to not talk too much while actually driving.
Hmmmmmm, can I add sidepipes to the heating and A/C in the house............
LOL
 
Barry,

Dropped Lady back off at Tony's this evening to have Tony do a mini-PV. Baby was on the lift and Keith was finalizing everything! In fact, we rolled Lady underneath Baby!

thanks for the update on BABY!! I'm waiting to hear from Keith this week to say she is ready to get picked up finally. It feels like she has been back there forever but i guess you know the feeling.
:)

Hopefully Thrus or Fri I can get BABY back!
