Tough to say,Ive never really looked at the stock pipes and collecter.Ive got Yosh stuff on mine,and I made my high mid-pipe from an 06' ZX-6 midpipe.....never had any stock exhaust parts on my bike.
I could buy the whole thing,then mod/weld that midpipe to fit my Yosh headers/collecter,sell you an entire system,then you could sell your stock headers/collector.Id still split the purchase cost fairly with you in the end,itll bolt up to your bike for sure,and youd be doing me a favor taking my old pipes that Id have to sell anyways.......anyone know if the stock and Yosh pipes have the same collector size/location?
We could do it lots of ways,lemme know what you think.....
