Title. I'm thinking about picking up the akrapovic GP full system and running it with the baffle in (currently running stock exhaust with the can removed as a quasi underbody) and was hoping somebody might know if it'll lean out the AFR at all? I've heard anecdotally that supposedly it will, and as the bike already runs fairly lean stock I'm not too keen on the idea of scorching valves or heaven forbid knocking the motor to death. I wouldn't think that anything exhaust side would change how the bike runs, but in case I'm wrong I figured I'd ask here. A power commander will be coming around the end of the year, and no I'm not interested in a different exhaust (well, except maybe the M4) or the stock exhaust. I heard and Akra R3 at work yesterday and it sounded so bloody nice that I NEEEEEED it. Provided I can run it without a tune that is.
