I'm uncertain that heat rejection (Corvette tranny tunnel) was all that great, but the applique's mass altered the natural harmonics of the panels, and the perceived sound level.

I wanted to have the best adhesion possible that I could find. Using a laser temp gun on the foam portions left in place inside and out, I found there was minimal difference between foam and the hushmat style. Whatever you think is best.

There is a big clearance difference between the body and turbo between my picture and yours in your other post on turbo leakage. Must be from year to year design changes I am assuming. PM me if you would like to go over it in detail.

You have made great progress.

Like Bruce suggested, I recently replaced my old hanging blanket with Hushmat. It was a fairly simple installation, the stuff really sticks. I did the install partly from the rear and partly from inside under the step. I also did the inside of the wooden step area, I haven't had a chance to really try it out yet and see if there is a noticeable difference. I'm thinking it has to be better than the old stuff that was just hanging down.

The hardest part for me was reaching in from the rear, it would have been easier if I was a little taller. To help things stick I used a 3" paint roller on an extension stick from the rear. I found I could get quite a bit of upward pressure and that I could actually use the crossover pipe for leverage. All in all it went well and as is my usual practice, I over bought, so I have enough left over to do my brother's engine compartment.
