You've got the 50 state legal slipons. I had the HD 50 state legal slipons and hated the sound. Performance was okay, but it sounded like a moped to me. I was able to locate a set of SEII's with BCT baffles on this site and I must say that I love the sound. They are smaller in diameter.

One problem I had with my slipons were that due to their larger diameter, they touched and this rubbed a spot on both mufflers. You might want to check yours.

Check the for sale section of this forum and also ebay for a set of SEII's for your bike. I would not drill the baffle deflector. If you can remove the baffle, then remove the packing and you can then drill additional holes to match the holes that are in the baffle.
