No answares?

The exhaust is the same on both models, the gs500e and the gs500f. I think the exhaust hasn`t changed in th years, or at least not changed a lot.

Ummm, he said GSX400E, not GS500F.   :dunno:

i dont know either.....find a gsx400 message board.... :dunno:

Isnt the GSX400 the bandit 400, I always thought it was, perhaps Im mistakin.  If it is then modification will be needed.

The GSX400e seems mostly like the GS400 twin, except that it had 4 valves per cylinder and 10:1 compression.  For example, see http://www.suzukicycles.org/GSX-series/GSX400E.shtml and http://homepage.sunrise.ch/mysunrise/joerg.hau/mot/gsx.htm#gsx400
