JustErik, that looks awesome. Unfortunately, Performance Spec now only seems to sell a different kind of elbow for the YS (black in color) that only connects to their aftermarket muffler and not the stock muffler that comes with the engine. Their mufflers are elso cigar-shaped (ie, no bend), so the orientation is a litte different. I wonder if that means I'll need the 75 degree adapter rather than the 90 degree one.
