You can start with air filter mods and maybe a low restiction muffler (similar to your stock muffler but pass-thru design internally).

Advance your ignition timing and use higher octane gasoline to avoid detonation.

You can gain some performance that way BUT your fuel economy will suffer.

Thanks for the inputs sir ghost rider...

I had already been using K&N drop in filter and 95 RON gasoline.. but I dont intend to advance ignition timing... hehe..
