Found a two brothers s/o on craigslist for a decent price that is off a zxr10... In his listing he mentions that it will fit on the f4i, and after comparing pictures it looks fairly close.... Does anyone know if it will mount up exact, or will it require some fab?

Thanks

 

Ask for the dimension center to center to center....make sure bolt hole align...

 

Also check your stock exhaust headers. Some have a slight bend at the end where mid pipe connects, some are straight. but 90% of two bros have the same exhaust diameter, but some such as the 250 have the same as a 600 but on the end has a converter.
