I decided to finally install my Madvette C5 insulation kit over the long Christmas weekend. Removing the interior was the easiest part of the job, taking less than an hour for the seats, carpet, and all the plastic side panels.




It was pretty easy to set all the pre-cut insulation pieces in position, but then getting it all taped down really slowed progress. I figured out (after finishing the job) that a hand held tape dispenser would have been a lot quicker than cutting the aluminum tape with a box cutter. I also spent some time using the extra pieces of insulation (plus some Frost King I already had) to fill in extra areas.




After driving to work today, I was able to notice the following differences:

• The exhaust tone is a little more muffled at idle
• I had to turn my manual temp control a little higher to get the interior warm (granted it was a cold day).
• I noticed with my SCV (speed controlled volume?) on my Bose set on the 2nd level, the radio was getting noticeable louder at speed.
• I now have zero squeaks from the door panels and side plastic covers.

It is very subjective to say the car is quieter on the inside, but when I had a passenger, we both noticed the radio volume was louder at speed where before the insulation it seemed to stay constant relative to the road noise. I was pleasantly suprised that this insulation was able to cut out the squeaks from the door panel. Part of them were a result of my Corbeau seats being a little wider and touching the plastic panels. But now it is much better over bumps, etc. I can still hear too much of the "sewing machine" valvetrain noise from my aftermarket cam, so I might try to add some more sound deadening material on the firewall.

Overall I would recommend this for anyone who drives their C5. You can learn quite a bit about the interior of your car by disassembling it, and it makes for a more pleasant time behind the wheel.

 

sounds pretty good, i bought his kit as well and along with AL roll tape, sitting my bedroom, some time this week i might do what the heck, i will get that tape dispenser as u suggest.

Thanks for sharing, seems like easy job but time consuming.

 

and now you know why this isn't done at the factory; very time consuming. But the rewards are well worth your time

 

I have the same kit in mine, I was looking to reduce exhaust noise after my engine mods, and it did cut it down a bit, took the edge off, don't sound quite so "angry" inside when I'm on the gas now, but it really reduced the road noise a lot more than I exepcted....

 

Thanks for sharing your experiences.
Makes it feel not so onerous a task!

Guess I should tackle mine any time soon....I just might wait until next year!

 

Did mine and love it - same kit too

Goes in pretty easily and quickly

Thanks,Matt
