They do and if you can't hear it you're either old or deaf. I'm used to loud cars so I'm not being picky.It doesn't hurt the paint or anything.. I've not had my hood liner or engine cover on my car since I December. As was mentioned the only thing I notice was more engine noise. If you are the type that gets worried bout every sound a car makes I suggest leaving them all in place. These engines make a good deal of valvetrain and DI system noise.
