ive owned both.

i prefer the "look" of the F.I.

i prefer the motorcycle high pitched sound of the stillen.

i like the weight of the F.I, and the customer service is the best of any company i have purchased from.

the stillen is cheaper.

the fitment of F.I is better, and more adjustable. i did not have any rubbing issues like others had with stillen, though.

seat of the pants cant detect any performance gains between the two.

the F.I has more drone, and can be heard while crusing. the stillen was silent. the stillen is louder at WOT, while the F.I is louder at anything under WOT.

(both were installed with HFC)

no clearance issues with either, and my car is lowered about one inch.
