This is what I did to baffel my end-curved pipes. First, I added exhaust tips, and as I have two and a quarter inch pipes and I cant find a mini baffel to fit them, I bought one and three quarter inch mini-baffels from JC Whitney and cut them just behind the large end of the baffel, which fits inside the end tip, then inserted the tip in the pipe. This provides some back pressure, quiets the pipes a little, but most important, when Leo stuck his stick in my pipe....it ran in to a baffel!

Just thought I would share this idea, as I know there are others out there with this problem.
