Is your bike a. Gen2 early model?No, it has four bolts so... :/
Better luck next time..
i fitted a gen2 system to my gen1 tuono.
had to cut off the 4 stud flanges and tig weld 3 stud flanges on the downpipes, also the front downpipe needs a little 'modification' (small dent with a hammer ) to make it fit round the oil cooler.
