Wondering.... Right now, before I get home, I have no exhaust. It goes header to chrome tips. Loud, obnoxious, and beautiful. I bought a PCV for it and I'm THINKING about getting an actual full system for it. For the meantime, does anyone know performance figures on it with no muffler? I read, here on hayabusa.org, that you can run a Busa with no mufflers, and it runs great. But what happens when I put the PCV on it? Which map should I use? I'm an idiot when it comes to fuel mapping. Where should I go to get maps? I sure in the hell don't want to mess up my baby because I retardedly messed with fuel. I work on jet engines, not bike engines, but I know what could happen. Any suggestions?
