Ebay Y pipe reviewed and dyno'd

Oh if you mean the other blips on the torque(which actually show as gaps in the power graph), I think the inductive ignition pickup was getting some interference or bad reading, but if you look at the rest of the graph it's pretty clearly where the curve really is.


The pipe is 2.5" to 3".
