After much debate & talking with some of the members on here, I went ahead and ordered a full Yosh R77 Carbon exhaust for my 2005 Busa. So far I know it has the O2 hole which I need to plug and I need relocate the hanger bracket to fit the Gen I. Anything else I'm missing? I was going to try and use my Yosh TRS header thats already installed on the bike but didn't want to cut and weld a 2 month old full system. Will be selling my Full Yosh TRS if the R77 works
