Giday Converse, believe it or not the silicone can handle the heat, weather it works or not I always put a bead around the mufflers when I refit one, same thing with the washer on the F/C's , silicone on both sides of the washer and put the clips on and that is about as good as you can get it, I just say to people, if the noise bothers you just put on a pair of ear muffs.
