of course not . It will just make it louder . I have a 2003 xr 80 r without a baffle , and it is louder and a little faster than the stock xr 80 , and I've been driving it like that for years and still runs as good as stock . So it does bump up your speed a little , but will let it breath better .

a crf 100 go up to 35 mph.
Yes, it does.
there is no crf 100 two stroke. it would be a four stoke and it has about seven hp.
it depends on who is riding . but the bikes are the same hp.
yes it is and it has 5 gears
