Well, it's possible to put a toomey silencer on a different headpipe..... the toomey headpipe has a big "B1" stamped on the front (pointed toward the shock)
x2 on the "B1" it looks like it has the greenish rubber "pipe clamp" that came with my toomey. Just a recommendation, you may want to put some clamps on that rubber pipe clamp (seen it 3rd picture).
