I have a lot of good things from the 250ex guys about a Pro Circuit T-4. As for jetting, Pro Circuit should recomend something and just but a couple jets not a full kit to save a little money. Keep your UNI filter. Good luck

I got a complete race system from Big Gun and it adds alot of ponies and tourqe.

t-4 is a great pipe, added a lot of torque and added 3-4 mph(or thats what it feels like) but defently more power
your uni is fine
i went to a 107.5 with a k&n and no airbox lid
