so i saw this post on another website but the guy never got answered so im wondering what kind of input you all have of this. Has it been done or can it be done...putting the exhaust from an f4i under the seat? you know same look as the 600rr exhaust. And yes i know a lot of you smartys out there are gonna say WHY DIDNT YOU JUST BUY THE RR for 500 more and blah blah. its just a question

 

i think if you have the tools, knowledge and time to work on it you should be able to pull it off. with all the things that havebeen done to customize bikes i think its possible.

 

i have seen an undertail exhaust on the f4i from either bikepics.com or some where else. sorry, i don thave the link but they do exist. you can alway go to meineke and have some custom pipes made and get some brackets made or from home depot.

 

I wonder if you could just buy the RR exhaust mid pipe back and bolt it right on, obviously you would have to do some work to your undertail but thats expected anyway. that might just work! lol
