+1 on Raammat. Can vouch that the BXT+Ensolite combo works as well, if not better, than anything else on the market and the cost can't be beat. Although the price of Raammat has gone up significantly in the last 5-7 years. Back then, I got the 60sq ft combo kit for about $180.
Anyway, I used these in conjunction with MLV (mass loaded vinyl) in my STI and while complete overkill it was as quiet as a coffin.
Yep. Butyl is leaps and bounds ahead of flashing for car audio. Much better at absorbing energy than flashing material due to it's thickness, and won't melt in heat the way flashing almost always does. All it really takes is one day of your interior baking in 100 degree temps and not only will flashing start gassing out, it will deform and start sliding off whatever its adhered to. Not going to be a very pretty install when you pull your door panels at that point.
@flashflooder; Peel n' Stick definitely is not the same as the high end deadening material... for the aspects mentioned above. But if you're looking for a way to kill your new car scent, this stuff can't be beat.
Agreed on all points! After reading, getting some small samples, and seeing a lot of documentation, I've decided to go with
Noico.
Here are my reasons for this, admitting that there are a number of excellent options, including the original Dynamat.
1) pure butyl compound, and not a composite with fillers, like
Siless, which while containing butyl, also contains other stuff (which is unknown - and which makes removal a nightmare as it reportedly disintegrates)
2) reasonable cost per sq ft
3) top rated product on Amazon among all the options (Fatmat, Dynamat, Siless, Kilmat)
4) not too stinky! Avoid those petrochemical-based roofing products unless you REALLY want CA, liver failure and CNS diseases!!
5) will adhere without heat gun (most products have this feature now - Dynamat used to be a bitch to put on for that reason!)
6) 80 mil thick, which appears to be a sweet spot for single application thickness
As downside, it is somewhat heavier than Siless and at 0.7 lbs per sq ft, not totally lightweight if you put in 50-60+ sq.ft
Will start project on our FL car, along with installing lightweight rotors, MPP Sport coilovers, and new drivers from Baddesign (when they come out).
