I only did 1 mile to test it so Ive not made up my mind yet.

Right went for a drive today, and I think it has made it louder - by about 0.00001%
Oh well, only took 30 seconds...
The foam is hollow, like a foam polo if you see what I mean.
Therefore I can't see it stopping anything...
Atleast I think it is.
Got a link dude, I fancy some of these!
