Drilling through firewall??

Was thinking about installing a boost gauge in my 1995 S-350 diesel and would like to know the best way to route the hose. I am kinda leary of drilling a hole through the firewall as good as Mercedes has the interior sealed off. Don't want a lot of air or road noise coming through. Any ideas??
