I was just wondering if there is anything i can do to improve the performance on my 2000 mountain lite 500

put a pipe on it someone made them but I cant remember who!

and the pipe will do what

around 10 more hp

haha omg, you will lose horsepower with a pipe unless u go twin pipes. all they do is make ur sled louder. unless of course you do twin/tripple pipes then you gain 10-20 horse.
