would a 2000 zx9r have the same mid-pipe and muffler diameter as my f4i???????????????????

 

I'll be the first to say, highly doubt it!

 

well the ninja runs a 2.5 and the cbr runs a 2.25.... so im going to go with one of two options... guy my yoshi pipe for its internals and re wrap it to make it sound better or just get something that can fill a .125" gap.....

suggestions?

i got the pipe for a stell its a muzzy carbon fiber pipe.. going to pick it up for around a hundo..... so ya couldnt turn it down... the cf alone is worth that......
