pipe on 250x ?

[250x]

any advice on the best performing pipe for my 250x? no other motor mods only one tooth smaller sprocket and went from 22" rear tires to stock 20" 400ex rear tires and fab'd a 400ex rear shock on it wich is hard but super nice!:devil

any aftermarket exaust will add power if you rejet the carb. I'll probably take alot of **** (oops, i mean poop) for this but i would stay away from DG and Cobra cause they are very loud and won't give as much power as say, a White bros.(Wich is the best)

Well said^^^^^^^^^^
Stay away from those he listed
Get a white bros
