Does this make the bike sound better and louder?

This would not make the bike louder, it would actually make the muffler a bit quieter really. It is not really made for sound it is simply a spark arrestor to make Yoshimura RS-2 mufflers legal for off-road use. Please note this will ONLY work on Yoshimura RS-2 mufflers.

Unfortunately they do not offer a spark arrestor for the Ti Carbon model on your 2010 YZ450f. It will only work in the aluminum exhaust.
