Performance mods for csc sg250

[Ashotd]

Hi everyone

I bought a CSC SG250 as my first bike two weeks ago and I already have 180miles on it. I was wondering if anyone could give me any advice on how to increase the performance of the bike. I was wondering if anyone could recommend air filters or ways of increasing airflow that would work on the 250 and if anyone knows of a better-than-stock exhaust system that would fit the bike and will increase performance? I would also appreciate any other suggestions that anyone has to increase performance.

Thanks for the help in advance!
