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.

Would this fit a stock exhaust on a 2007 crf250r?
The question is about the yoshimira spark arrestor insert..

No. This will only fit Yoshimura TRC Mufflers.

Will this insert work with the carbon fiber rs4 muffler.?
2010 YZ 450 f Yoshimura Ti/Carbon full system

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.
