Did it tone down the exhaust droan at all? I have a 61 ragtop Impala with a 383ci sbc and 50 series flowmasters on it that can get to be a little much. I want to use some second skin products to take care of it and was wondering exactly what difference it made for you?

I'm running 2.5 inch Flowmasters with an X pipe. I have one layer of regular Damplifier and and one layer of the thiner Overkill. both have 100% coverage. Even without the bottom part of the back seat in, there is no drone. You know the engine is alive when you step on it, but you can have a normal conversation and even use the phone when just cruising.

Just to add my.02... was in Lowe's the other day, needed some roofing stuff, saw the roof tape, looked it over and decided to punch a small hole in the plastic, took a whiff and put it right back down. The asphalt used STUNK! I can't imagne putting an asphalt based product in the car, what would it stink like in the heat of summer, don't want to breathe all those toxins in, might wind up growing an extra arm or something. They did however have a "butyl hybrid" tape, didn't smell but was very thin, hmmmmm.....
