DV or Don or?,

I have side pipes from CR that I got about 1 to 1/2 years ago. The problem I am having is that the are quite loud. I know Cobras are supposed to be loud but it idles at 95 Db and at 3000 rpm it's at 105 Db. Is this normal? Also I saw in a thread somewhere that these are too restrictive. Should I just replace these? And in your opinion, with what?
Thanks for you time I appreciate it.
