Usual things panel filter or induction kit,throttle body,striaight through exhaust. To be honest none of these will hive you much if any bhp gains will sound louder/better but thats about it. For some real power increases you are looking at head skimming and re-mapping the ecu etc.tyger1111 said:Hi people
