exhaust and jet kit

[luvmykatana]

I have a 2001 gsx750 I have put a yoshi rs3 on it and the can has some dents in it.I would like to replace cover on can to improve the looks and performance of this muffler where can I get the cover for this slip on can. I would also like to put a jet kit in the carbs they have a little miss in them at about 3K rpm so I would like to get carbs cleaned and the kit installed.Will I need carbs synced after having jet kit installed and anything else I need to know or need with these mods.
