For the Vance & Hines Big Radius 2 into 2 on a Harley Davidson the part number for the Original Thunder Monster baffles is 2002 and for the Quiet Series part number QBL 1845. Part numbers 2001 and QBL 1994 will NOT fit. For Metric applications the part number for the Big Radius 2 into 2 is 2000 or QBL 2125.
