Owners manual says to change plugs every 15,000 so changing them should help, you might do a basic tune up too, check your PCV hoses and valve if there is one, check the inside of your cap and the rotor tip as they sometimes need to be cleaned up a little as time goes on, check your timing, check your valve lash, I know that with stock exhaust the valve lash hardly ever needs adjustment but with over sized exhaust it's hard to say what kind of wear you could see.
