What to put on my 250 ex

Hey, what exhaust would you recomend. I am looking at a pro circuit t-4. Anyone have any coments. I am also looking at a k&n filter. i was looking to jet it but one guy had some problems doing that to his 250ex and i dont want to get into that. Will i notice a huge difference with these mods and is it worth spending the extra money for a complete system than buying a slip on.
thanks
