a sparks timing advancement key would help you out as well. IMO a full exhaust wont make a HUGE difference over a high quality silencer. It will obviously add some power but for rec riding I would just go with a nice silencer. 400ex's make a surprising amount of power and you cant beat the downlow grunt while on tight trails!
Happy riding
