Hayabusa muffler is cheap till you buy the 220.00 mid pipe,the FMF is actually built for the bike.
FMF just seems like less hassle as long as a person can repack it at some point. Im not too sure about having a GSXR muffler sticking way the heck out the back of the bike,what happens if the bike falls down?

I just run the stock muffler and dont worry about it.
Some bikes around at times
