I was thinking about getting the Team Alba Slip-On Pipe [LTZ400-30010] so i emailed alba about it and the guy wrote me back and said you dont need to rejet to run this slip on if u run the stock airbox with the lid and the stock header,i thought i read somewhere that the kfx400 was jetted on the lean side from the factory,if thats true i dont see how u can run this slip on with out rejetting.

anyone running this slip on on a stock kfx400?
