change all spark plugs to premium plugs, upgrade ignition cables or coils to performance type(accel's), upgrade air intake to high air flow type(K&N). TREAT FUEL SYSTEM with stab-bil ethanol cleaner. your cats do not control exhaust burn but act as a filter. use high grade oil. your engine is not burning efficiently.
