You could always call up Randy and ask. He makes them by hand from your stock muffler, so it wouldn't surprise me if he did it to a blast muffler. He is a really nice guy, so don't be afraid to call and ask. Though a fiberglass-type muffler would probably sound much better on the blast. I have a Kerker on my Blast and it sounds pretty mean. The Hawk on my Lightning definitely sounds better, but that is probably more due to it having twice the cylinders and over twice the displacement.
