Don't quite know what this pipe is, came with a tri z. Fits fairly good, pretty tight to the cylinder but there's clearance and has the indent for the motor mount bolt on the side of the frame (inner side of pipe). As you can see lined up next to a stock pipe the stinger is a bit longer and I took a pic of where it pops out behind the fender. Don't think its a sectional hand built but up by the top hanger mount there are a few sections. Anybody recognize it??? thanks
