mivv also makes a gp pipe like the one im trying to find above...but im more interested in this one because it has a more aggressive "high exit"...im positive its not arrow because an arrow badge sticks out like a sore thumb and arrow never made the gp pipe for F4is...the only person that i know of that has this on his F4i retrofitted it from a 600RR...

OMG, ill paypal some money to the first one that can identify this freakin' pipe!!! [:@]

 

So .... How much money are we talking about ???? j/k
it kinda looks like a hindle ..megaphone/sidewinder .... or a kerker megaphone ..

 

may be its custom made !
