...a 600RR pipe would work on the f4i? I think I want un under the tail pipe, any suggestions?

*I have an '01 f4i

 

it would take lots of custom work and you would have a huge midpipe that goes from the header around the side and then to the undertail. then you would have to fab up an undertail that would hide most the muffler and not melt. so basically, if you want to take the time and effort, you COULD make it fit, but it will not be easy.
