out of curiosity what have people used for trumpets when using gsxr throttle bodies?

GSXr's have an air box which has rubber trumpets inside. I have a spare set of these (think they are 54mm i/d if your interested). They come in pairs (2 x short + 2 x taller).

I was thinking of fitting the rubber bike trumpets for my TB convertion but have heard they are too short?
