So I found a X40F0X! Just kept calling local scracyards until I got lucky! Should be comming in today I am now looking into building a mid-pipe---or having one built that is. I have access to a fabrication shope with all that I need: pipe benders, welders, and the talent to do it. Any help or reccomendation that anyone can offer? Pipe dimentions, bends, etc? I was also wondering...are there any additional gaskets from the flange into the exhaust or mid-pipe into the motor that I should know about? Sorry guys I'm pretty new to this. Finally, I have it Jetted for a 600-750 GSXR exhaust...bought it like that. Will I need to re-jet for the GSXR 1000 can?
